Good afternoon, everyone.

I need your support regarding the issue below.

My client has SAP ICS integration and requests advances through the Request.

To have complete mapping and identification of the advance request during expense settlement, it is necessary to have a unique identifier code between the expense and the request. The client requests that it be the RequestID. However, we already known that the Request ID is not identified within the JSON.

Do you know if there is any other way to create a common identifier between the expense and the request that can be sent to SAP FI via JSON without using an API?

Thank you
