Quick answer: An SAP native journal entry workflow runs inside SAP ECC or S/4HANA as an add-on. Journals are validated against live SAP rules, approved through SAP roles and recorded with the SAP posting history in one system. Workflows beside SAP run on SAP BTP or a vendor platform and exchange data with SAP through APIs. That adds data copies, separate permissions and split audit evidence to govern.
Finance leaders are routinely asked to demonstrate who prepared, validated, reviewed, and approved each manual journal. When these activities occur across spreadsheets, workflow applications and SAP, the supporting records may be held in different systems. This can complicate control oversight and audit evidence retrieval.
An SAP native journal entry workflow can keep validation, approval and posting connected to the organisation’s SAP data, authorisations and audit records. Workflows operating beside SAP may provide similar capabilities, but finance teams need to understand how data, controls and evidence move between the application and the ERP.
The assessment begins with four stages: preparation, validation, approval and audit evidence. The location of each determines the controls and dependencies an organisation must manage.
Where Do Journal Preparation, Validation and Approval Happen in an SAP Landscape?
Under its on-stack vs side-by-side extensibility model, SAP describes two broad ways to extend S/4HANA: on-stack, where the extension sits on the S/4HANA system itself, and side-by-side, where it runs on SAP Business Technology Platform (BTP) and connects through APIs.
Journal workflow solutions generally follow three architectural approaches:
- Native SAP (on-stack) : the workflow is installed in the SAP system as an add-on and works with SAP's own data, rules, and authorisations
- Side-by-side on SAP BTP : an SAP BTP journal entry workflow runs on SAP's platform, outside the S/4HANA core, and exchanges data with it through APIs.
- External third-party platform : the workflow runs on the vendor's own servers or cloud, using APIs, connectors or middleware to exchange information with SAP.
For example, SAP offers a Journal Entry Posting Approval content package that runs on SAP Build Process Automation or SAP Workflow Management and posts approved journals to S/4HANA.
SAP supports side-by-side extensibility as part of its clean core approach. It can be appropriate where organisations need extensions that operate independently of the ERP core. The relevant architectural consideration for journal processing is how each solution handles validation, approval authority and control evidence.
Where each journal stage operates
In short, preparation looks similar in all three models. The differences appear at validation, approval and evidence.
Preparation in Excel is common across all three approaches. The architectural differences become more significant when a journal needs to be checked against SAP rules, authorised for posting and supported with retrievable evidence.
Journal Entry Data Replication: What Moves When the Workflow Sits Beside SAP
A workflow operating outside SAP needs access to relevant financial and reference data. Depending on its design, this may include G/L accounts, cost centres, profit centres, company codes, posting-period status and user or approver information.
The application may retrieve this information through live APIs, maintain locally cached reference data or replicate selected SAP records into its own environment. These approaches create different data-management requirements.
Where information is copied or maintained separately, finance and IT teams should assess three risks:
- Synchronisation risk : Replicated master data or posting-period information may become outdated between refreshes. A journal could pass an external check but fail when SAP applies its current configuration.
- Data security risk : Copies of sensitive financial information introduce additional storage locations and access permissions that must be secured and monitored.
- Governance risk : Additional data stores require clear responsibilities for classification, retention, deletion, and access management.
IBM’s 2026 Cost of a Data Breach Report reports that breaches involving data stored across multiple locations took an average of 256 days to identify and contain, compared with 247 days across all breaches studied. Although these figures do not specifically measure SAP journal platforms, they provide wider context for the security considerations associated with distributed data.

Do journal automation tools replicate SAP data?
Many external journal automation tools may store copies of SAP data, while others retrieve information through live interfaces without maintaining the same level of persistent replication.
Buyers should establish what data leaves SAP, whether it is stored or only transmitted, how frequently it is refreshed, and which controls protect it. These details are necessary to assess external journal entry platform risk.
Should Journals Be Validated Against Live SAP Rules or a Replicated Copy?
Every journal must satisfy the relevant SAP posting requirements before it enters the ledger. These may include account and cost-object validity, posting-period status, document balancing, and configured validation and substitution rules.
An external workflow may use its own validation rules, replicated reference data, or live SAP interfaces. Where the checks do not cover the full SAP posting logic, certain errors may only become visible when the approved journal is sent to SAP.
For finance teams, this can mean additional corrections, renewed review, or resubmission during the close.
In an SAP native journal entry workflow, a journal can be tested against the same live configuration that will govern its posting.
Promenta applies this by building a fully validated virtual journal document when the request is raised and running a simulated posting before the journal enters approval. The requester can correct errors identified by SAP before the document reaches the approver.
Journal posting simulation in SAP does not remove the need for final controls if relevant SAP configuration or posting conditions change before the document is posted. It does, however, allow many avoidable errors to be addressed earlier in the process.
How Does Journal Approval Inside SAP Use Your Existing Identity Model?
Journal approval inside SAP uses the users, roles and authorisations the organisation already maintains and audits. Approval responsibilities can therefore be managed alongside the SAP access controls governing financial transactions.
When approval operates on another platform, the organisation must also govern that application’s permissions and their relationship to SAP posting rights. This does not necessarily require a completely separate user directory: SAP BTP and third-party applications can integrate with existing identity providers.
Two control considerations remain :
- Access management : Changes to an employee's responsibilities or employment status must be reflected in every application through which that person can access or approve journals.
- Segregation of duties (SoD) : Approval permissions and SAP posting authorisations need to be assessed together so that users cannot bypass the intended separation of responsibilities.
Where should journal entries be approved?
For an SAP-focused finance function, managing approval within SAP can simplify the relationship between approval authority, posting permissions and audit evidence. Where an external approval platform is used, equivalent controls need to be demonstrated across the connected systems.
Promenta supports requester-versus-approver controls within SAP, including configurable restrictions on self-approval. Organisations can also restrict direct posting authorisations and use a controlled posting process so that users cannot bypass the configured workflow.
Where Is the Journal Audit Trail Stored, and What Does Your Auditor Have to Test?
When approvals run outside the ERP, approval history may be retained on the workflow platform while the resulting financial document and posting history are stored in SAP.
The organisation must be able to establish two things:
- Every posted journal followed the approval process required by the organisation's policy.
- The journal posted in SAP corresponds to the version that received approval, including any subsequent amendments or exceptions.
Some platforms provide integrated reporting or automated reconciliation across these records. Where they do not, finance teams may need additional procedures to establish a complete audit history.
Location also affects audit scope. Under PCAOB AS 2601, an auditor considers controls at a service organisation where that organisation’s services form part of the entity’s relevant financial information system.
An externally hosted journal platform may therefore bring service-provider controls into consideration, depending on the nature and significance of the processing performed. A relevant service auditor’s report, such as a SOC 1 report, may be one source of audit evidence.
With a native SAP journal workflow, the requester, approvers, supporting attachments and posting record sit in one system and can be reported together. This can reduce the effort required to assemble and reconcile journal evidence across applications.
Auditors must still assess the relevant controls, including user access, changes to workflow configuration and the effectiveness of approval procedures. An SAP-native deployment does not remove those requirements.

Journal Entry Integration Architecture: Middleware, Infrastructure and Upgrade Exposure
Journal workflow architecture also affects the systems IT must maintain, secure, and test.
An application operating outside the ERP introduces an additional runtime or service and interfaces connecting it to SAP. The extent of infrastructure management depends on whether the solution is deployed on SAP BTP, operated by a third-party vendor, or maintained internally.
SAP add-on vs. BTP vs. external cloud platform: operational considerations
A native SAP add-on can reduce dependence on external workflow infrastructure and middleware for the core journal process. It must still be tested for compatibility with relevant SAP upgrades, support packs and configuration changes.
Deployment support should also be checked against the organisation’s target SAP environment. SAP ECC, S/4HANA on-premises and S/4HANA Cloud Private Edition may support different installation and extension approaches.
Questions to Ask Before Choosing an SAP Native Journal Entry Workflow
Finance and SAP teams can use the following five questions to establish where processing and control responsibilities sit in a proposed solution.
Promenta operates natively within SAP, allowing journal preparation, workflow, validation and audit information to be managed through the existing SAP environment.
- Does the solution keep journal data, master data references and supporting attachments within SAP, without requiring copies in another application?
- Is the journal validated against live SAP configuration before approval?
- Are approval permissions governed through the organisation's SAP access and identity controls, with segregation of duties maintained?
- Can approval records, supporting documents and SAP posting history be retrieved together without manual reconciliation?
- Can the journal workflow be maintained and tested through SAP upgrades without dependencies on additional application environments?
Any answer that is unclear or does not meet the organisation’s requirements warrants further examination of the relevant interfaces, data stores, controls and support responsibilities.
The checklist also provides a practical basis for evaluating a journal entry solution for SAP without assuming that every implementation follows the same architecture.
How Promenta Keeps Every Journal Stage Inside SAP ECC and S/4HANA
Promenta’s SAP Journal Entry Workflow is built natively on SAP, so the core journal process, including validation, approval, supporting documentation, and audit reporting, operates within SAP ECC or S/4HANA. Finance teams can continue preparing journals in Excel through the Promenta Add-In or use the web-based interface.
The solution validates journals against live SAP finance rules, performs a posting simulation before approval, and uses configurable routing to manage review and authorisation. Approval decisions, attachments and posting records remain available within SAP for reporting and audit purposes.
As an SAP embedded journal entry tool, Promenta does not require separate external servers or middleware for its core workflow. It is an SAP-certified solution supporting ECC and S/4HANA, including applicable on-premises and private-cloud deployments.
The architecture allows organisations to build on existing SAP security, configuration and governance processes while reducing additional integration dependencies.
Conclusion: When Does an SAP Native Journal Entry Workflow Make Sense?
The location of journal processing determines which systems must be maintained, which controls need to be coordinated and how finance teams retrieve evidence of each transaction. An SAP native journal entry workflow can bring these responsibilities closer to the system that ultimately records the financial document.
A controlled journal process can follow this sequence entirely within the SAP workflow, while still allowing Excel-based preparation :
- Prepare : the journal is prepared in Excel or an SAP-based interface.
- Validate : the journal is checked against live SAP configuration, including a posting simulation.
- Submit : the validated journal is submitted for approval.
- Route : configurable rules send the request to the right approvers.
- Review : approvers review the journal and its supporting documents.
- Approve : the approval decision is recorded against SAP users and roles.
- Post : the approved journal is posted to the SAP ledger.
- Audit : the request, approvals and posting record are reported together in SAP.
For finance leaders reviewing their current approach, two questions deserve consideration:
- If an auditor requested the approval history for last quarter's posted manual journals, how much work would be required to produce a complete, reconciled record?
- When a journal fails a final SAP posting check after approval, which team owns the exception and how is the corrected journal reauthorised?
The answers help reveal whether journal controls operate as one governed process or depend on additional coordination between systems and teams.
Frequently Asked Questions
1. Where does journal preparation, validation and approval actually happen in an SAP landscape?
Preparation often takes place in Excel or an application interface. Validation and approval may run inside SAP, on SAP BTP or through an external workflow platform. The location and integration design determine which SAP controls can be applied before posting.
2. What are the risks of approving journals in a platform outside SAP?
Potential risks include differences between SAP and application-level validation, inconsistent approval permissions, additional data storage and fragmented evidence. These risks depend on how the platform integrates with SAP and how its controls are configured.
3. Where is the audit trail stored when journal workflow sits outside the ERP?
Approval activity may be stored on the external platform while SAP retains the posting record. Organisations should confirm whether the solution links the approved request to the final SAP document and supports reporting without manual reconciliation.
4. Does an SAP native journal entry workflow require external servers or middleware?
A native SAP add-on does not necessarily require either for its core processing. Promenta’s SAP Journal Entry Workflow operates within the existing SAP environment without an external workflow server or separate middleware.
5. How does an SAP-native architecture change what an auditor can see?
It can allow auditors to retrieve the journal request, approval decisions, supporting documents, and posting history through SAP-based reporting. This simplifies evidence retrieval, although the underlying controls and their operating effectiveness must still be tested.
