Hi....
If you transfer billing document from SD to co-pa
without costing key, co-pa don’t get cost component data of Standard COGS.
Using t-code KE21N, You can create direct co-pa document,which
have cost component data of Standard COGS, releated to billing document.
But SAP don’t occur FI document as soon as MM document
is created because Material which have price control “S” don’t have Standard cost.
Through monthly actual costing job, you can create FI document which have actual COGS.
