I have a created a service based transaction in CRM and wish to use CRM Billiing to create a billing document and transfer it to FICA in our ERP system. We do not need any controlling functionality so I followed KBA 994326 and created an implementation for BADI BILL_ACC_IF and in the ENRICH_ACC_DOCUMENT method I cleared the EXT_OBJECT_ID and BUS_SCENARIO fields in the CT_ACC_ACGL09 structure.
The billing is working fine but when the billing document replicates to ECC I get this error:
Field Base Unit of Measure must be blank (Account XXXXXXXXXX XXX) Message No. >0083
Any help much appreciated !
