All,
We have created an I/C sales document type ZIRS. When I looked at the material document that we used on this order We have a problem with the material not assigned to the sales document. However, when I looked at the billing document that is associated with the sales document has material group4 assignment. Because of the sales document has no material group assignment, the table VBAP is not picking up the value. Why it's happening and how we can resolve this.
