Need ERS invoice number in Accounting Document
The client wants the ERS invoice number populated in the Assignment (ZUONR) field of the Accounting document. He wants this done at the time of invoice creation via MRRL.
The exit MRMH0001- EXIT_SAPMRMH_001 is not helping, for the invoice is not yet created when the exit is processed. Means, the invoice number is not yet there.
Kindly suggest a solution how to take care of this challenge.
Thanks in advance
