Contract request fails to send to SAP S/4HANA via CIG with Error 500

[Shella]

We have created a contract workspace in Ariba CLM, and the CLID document has been published. We are now attempting to integrate the contract request into SAP S/4HANA using the standard add-on integration via CIG. All required configurations have been completed, including the setup of endpoints from the SAP Business Network. However, the error occurs immediately upon sending and does not even reach CIG or the Ariba Business Network.

When we click "Send to External System", we receive the following error:

"Contract Request document could not be sent to the external system. Error Message: Status code: 500, status text: Internal Server Error, status message: Integration Error."

This is the only entry recorded in the document's History tab.

From the Contract Workspace Overview, under External System Configuration, we have the following values:

• Company Code: XXXX

• Purchasing Organization: XXXX

• Purchasing Group: XXXX

• Document Type: Contract

• Document Category: WK Value Contract

Could someone please confirm if the Document Type and Document Category values are correct? We're unsure if these are contributing to the error. Any assistance would be greatly appreciated.

Hi Shella,

It seems required Integration tasks are not disabled. Could you please refer the below documentation.

Hi Basavant, thank you for your response. We have disabled the Purchase Contract to S4 HANA via CIG but still encountered the error. We are using the regular add on integration not the 4AZ since it was mentioned by SAP CIG support team that 4AZ is not compatible and will not work with the regular add on integration. We have already Ariba SLP live in production that's why we can't change the CIG connection type.
