Custom fields from the CRM contract to the ECC Debit memo Request

Hi Everyone,

I need to send custom fields from the CRM contract to the ECC Debit memo Request. CRM contract to the ECC Debit memo is not a replication, it is done as a creation event via the CRM Middleware and the custom fields are not included in the standard container.

I see function module on the CRM side to send data from CRM contract is “CRM_R3_SERVICE_BILLING_UPLOAD” and function module on the ECC side to process the data and to create the Debit memo request is “CRS_SERVICE_BILLING_PROCESS”. I need to enhance to send custom fields. Can anyone please help me how to send custom fields.

Thanks,

Praveen
