Record types

SAP S/4HANA records to discuss.

These SAP S/4HANA record examples help scope a technical review. They are not a list of verified Stacksync operations.

Business Partners
Determine whether each customer represents an individual, a company, or a business-unit relationship before matching it to a contact or organization. Retain the source customer ID and destination ID; names and email alone are insufficient.
Sales Orders
Preserve both the order ID and stable line IDs. Allow one order to relate to several shipments or invoices.
Purchase Orders
Retain purchase-order and line IDs together with the supplier and legal-entity context.
See 3 more record examples
Products / Materials
Distinguish the product ID, variant ID, SKU, and price-list entry; they are not interchangeable keys.
Billing Documents (Invoices)
Retain the invoice ID, issuer/legal entity, and original order reference; invoice numbers alone may overlap.
Deliveries
Identify this record type and the operation you need to review with Stacksync.
Connection setup

SAP S/4HANA connection requirements.

Review SAP S/4HANA access and the operations your workflow needs with Stacksync. The vendor API reference below can help your administrator prepare for that discussion.

Prepare access and scope for the engineering review
  • Identify the SAP S/4HANA account, edition, environment, and business objects the integration must access.
  • Confirm a Stacksync connector or implementation path for SAP S/4HANA, including read/write support, authentication, and initial-load limits.

Integration design

Match records and fields for your SAP S/4HANA integration.

Choose whether the integration moves master data, reports transactions, or creates an approved financial document. Preserve entity, currency, accounting period, and header/line references.

Use these design questions to prepare a representative record and the business rules your integration must preserve.

Source product ID · SKU or variant reference · Description · Unit of measure · Price-list reference
Related records to resolve first
Resolve units, variants, categories, and applicable price lists before order lines.
Test before going live
Test two variants of one product, a changed SKU, and a price that applies to only one market or currency.

Sales Orders

Confirm object support with Stacksync

Identity
Preserve both the order ID and stable line IDs. Allow one order to relate to several shipments or invoices.
Fields to consider
Source order ID · Customer reference · Line references and quantities · Order status · Currency
Related records to resolve first
Create or locate the customer and products first; resolve taxes, currency, and fulfillment references.
Test before going live
Test a multi-line order, a partial cancellation, and two partial shipments. Compare line totals as well as the header.

Purchase Orders

Confirm object support with Stacksync

Identity
Retain purchase-order and line IDs together with the supplier and legal-entity context.
Fields to consider
Source purchase-order ID · Supplier reference · Line references · Quantity · Approval status
Related records to resolve first
Resolve supplier, product, business unit, and delivery-location references before lines.
Test before going live
Test a partially received purchase order and an amendment after approval.

Setup and validation

Validate the SAP S/4HANA integration in four steps.

Reconcile totals within the same entity and currency. A repeated delivery does not post the same financial transaction twice.

View the four setup tests and expected results

  1. Confirm the intended SAP S/4HANA account and grant

    After confirming an implementation path, validate the selected access method with the intended account and environment. Check that the authorizing user can grant access to the selected objects; test reauthorization without changing the mapped record identity.

    Expected result: The connection reaches the intended account, and the integration owner can renew or revoke the grant through the agreed procedure.

  2. Test record matching for Business Partners

    Using the implementation established in the compatibility review, preserve the selected source ID and resolve the required references. Test an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact.

    Expected result: Reconcile totals within the same entity and currency. A repeated delivery does not post the same financial transaction twice.

  3. Test the operation your workflow needs

    Review one SAP S/4HANA record with a Stacksync engineer. Confirm how it should reach the other system, how often it must update, and whether your workflow needs reads, creates, or updates. Test those operations before expanding the integration.

    Expected result: The selected operation is confirmed, addresses the intended record, and exposes rejected values for repair.

  4. Test recovery and name the support owner

    For the confirmed implementation, interrupt a non-production transfer and restore access. Establish whether recovery uses the current source state or a stored historical event, and verify that repeated delivery preserves record identity.

    Expected result: The records have the expected current values, repeated delivery creates no duplicate business record, and your team knows who handles unresolved errors.

Use the production-readiness checklist to record test results, assign support owners, and agree on when to go live.

Troubleshooting

Troubleshoot your SAP S/4HANA integration.

Diagnose record matching, delayed changes, and rejected operations
A SAP S/4HANA record appears under the wrong destination record
Determine whether each customer represents an individual, a company, or a business-unit relationship before matching it to a contact or organization. Retain the source customer ID and destination ID; names and email alone are insufficient. Resolve person or company type, legal entity, business role, and any billing account before transactions. Repair the ID relationship before repeating the operation.
The first load looks correct but later results differ
Confirm the selected SAP S/4HANA implementation’s change-detection method for Business Partners, Billing Documents (Invoices) and Journal Entries. Compare later changes with the original source rather than using a successful initial copy as evidence of ongoing capture.
One operation succeeds while another is rejected
Check the specific SAP S/4HANA object, field permissions, required references, and allowed operation. A successful read does not establish that a create, update, deletion, or business action is available.

Review retry, replay, and recovery behavior before repeating an operation that may already have succeeded.

FAQ

SAP S/4HANA connector FAQ

How should I plan an integration with SAP S/4HANA?

Choose whether the integration moves master data, reports transactions, or creates an approved financial document. Preserve entity, currency, accounting period, and header/line references. Confirm the connection and read/write operations with Stacksync. Start with one workflow, agree on which fields each system owns, then test initial data, later changes, and recovery before expanding.

Can the SAP S/4HANA connector write changes back?

Write-back support is not established for this connection. Review the SAP S/4HANA records and fields you need with a Stacksync engineer, then test the required operation with a representative record.

Which identifiers should I preserve for SAP S/4HANA data?

Determine whether each customer represents an individual, a company, or a business-unit relationship before matching it to a contact or organization. Retain the source customer ID and destination ID; names and email alone are insufficient.

Which related records should I load first for SAP S/4HANA?

Resolve person or company type, legal entity, business role, and any billing account before transactions.

How do I validate SAP S/4HANA changes after the initial load?

Test an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact. Reconcile totals within the same entity and currency. A repeated delivery does not post the same financial transaction twice.

What will we cover in a SAP S/4HANA integration demo?

Start with one workflow and a sample record from Business Partners, Billing Documents (Invoices) and Journal Entries. We can review how to identify the record, connect related data, set the update direction, and test recovery. Include the person who owns the source system and anyone who will maintain the integration; you do not need a finished requirements document.
