I created a new sort key (040) under OB16 - as excise invoice number (XREF3) - and inserted this new sort key in the customer master.
now all the txns that take place, the line items should be sorted based on the excise invoice number.i.e. the excise invoice no. should reflect in the assignment column of FBL5N.
But it is not happening.
what have i not done in order to have the excise invoice no. reflect in the assignment column of FBL5N?
Thanks for your responses
