Dear Experts,

We are creating service order with multiple line items and each line time is having different Bill to party while creating Debit Memo Request with reference to service order system is picking Bill to party from header and not from item level  Bill to.

Our requirement is system should pick ‘Bill to party” from item level NOT from header level always whenever we create debit memo request with reference to service order if Bill to party is different from header level.
