Changing partners on SD billing document
Trying to find a way to change an item level partner on an SD billing document. Not trying to change SOLD-TO or SHIP-TO partners. Trying to change a custom partner function that was defined for SALES REPRESENTATIVE.
The IMG has configuration to "Set Up Partner Determination for Billing Item", The partner functions are listed and there is a checkbox labeled "Not Modifiable". The checkbox is unchecked for this custom partner function.
When using transaction VF02 to change the billing document, all of the fields on the partner screen are set for output only. Traced through the code and it looks like the partner screen is always set for display only.
Can you change partners on an existing billing document without cancelling the document, updating the original document (sales order), and recreating?
