The role of SAP Business One and the role of Chainlink
SAP remains the system of record for the business. Chainlink directs the work on the warehouse floor and posts the result to SAP. See WMS and ERP.
Data exchanged
Each document includes its lots and serial numbers. You select the flows, the frequency and the warehouse mapping.
- Items, with barcode, unit and lot or serial number management
- Suppliers, customers and warehouses
- Purchase orders to receive
- Sales orders to pick
- Inventory transfer requests
- Receipts, as goods receipt POs
- Shipments, as deliveries
- Transfers, as inventory transfers
- Count differences, as goods receipts or goods issues
- Items and business partners created in Chainlink
How orders close in SAP
Each document is posted as a copy of the order, line by line, so SAP closes the lines as if the document had been entered in SAP.
- A partial receipt leaves the pending quantity open
How duplicate documents are prevented
Each submission carries a Chainlink reference, in Remarks or in a field such as U_CL_Ref. A retry never creates a second document.
- The Submissions tab shows each status and the document number SAP assigned
Confirming that SAP and the warehouse match
Every night, and on demand, Chainlink compares stock by item and warehouse.
- A difference with pending submissions usually closes when they are posted
- A difference that persists indicates a movement made outside Chainlink
Connection requirements
- SAP Business One 9.3 or 10.0 with the Service Layer, on SQL Server or SAP HANA
- The Service Layer reachable over HTTPS
- The company database and a user dedicated to Chainlink
- Optional: a user-defined field for the reference
The password is stored encrypted. When the connection is saved, Chainlink performs a test read.

Frequently asked questions
For any other question, contact sales.
Does it replace the inventory module of SAP Business One? +
No. SAP Business One continues to manage purchasing, sales, accounting and inventory valuation. Chainlink executes in the warehouse what those documents require, by location, lot and serial number, and sends each receipt, delivery, transfer and adjustment back to SAP.
Does it work with SAP Business One on SQL Server and on SAP HANA? +
Yes. The connector uses the Service Layer of SAP Business One 9.3 or 10.0, which is available on both databases.
What happens if SAP does not respond? +
The submission changes to «Retrying», and Chainlink retries it automatically after 1, 5 and 15 minutes, and after 1, 3 and 6 hours. If SAP rejects a document because of a data or permission error, the submission changes to «Requires attention» with the SAP message.
Is an add-on required in SAP Business One? +
Not for the direct connector, which connects to the Service Layer with an SAP user. Optionally, a user-defined field on the documents, such as U_CL_Ref, stores the Chainlink reference; without it, the reference is stored in Remarks.
