Connecting Cimmra to SAP: an integration walkthrough

The first question in every enterprise evaluation is some version of: "We run SAP. What does the integration actually look like?" Fair question, because a procurement platform that does not stay in sync with the ERP just creates a second version of the truth. Here is what moves, in which direction, and when.

What flows from SAP to Cimmra

• Master data: company codes, plants, cost centers, GL accounts, material masters, and the supplier master. Synced on schedule or on change, so a cost center created in SAP is available for a purchase request in Cimmra the same day.
• Budgets: where budget checks live in the ERP, Cimmra validates requests against them at the point of request, before commitment, not after.

What flows from Cimmra to SAP

• Purchase orders: approved POs post to SAP as the financial commitment, with cost assignments intact.
• Receipts: GRNs recorded against POs flow back so inventory and accruals stay correct.
• Invoices: matched, approved invoices post to accounts payable ready for the payment run. Cimmra handles the matching and approval workflow; SAP remains the ledger of record.

How the connection is built

Integrations run over REST or SOAP APIs, IDocs, or file-based exchange where that is the standing pattern, with field mapping agreed during implementation. Errors are queued with reasons and retried, not silently dropped, and every synced document keeps a cross-reference to its counterpart, so tracing a PO from Cimmra into SAP takes one click, not a support ticket.

The same architecture applies to Oracle, Microsoft Dynamics, Tally, and NetSuite. Typical integration effort runs alongside implementation rather than after it, so go-live means the whole loop works, not just the front half.
