Hi,
Basic excise duty is wrongly picked in to debit memo as explained below
1) Depot sales order: creted for qty 1
   Basic excise duty 80
2) delivery created:
3)depot excise invoice creted: Adjusted depot stock aganist plant excise invoice 123 and basic excise duty is 100
4) created depot invoice; CAPTURED BASIC EXCISE DUTY IS 100 which is correct (356 movement type assigned to basic ex duty in pricing procedure)
Depot returns:
1)returns sales order created with referance to depot invoice
   copied basic excise duty as 1000 (which is correct)
2) cretaed credit memo request: Here basic excise duty is 80 wronly copied from depot sales order instead of 100
Please provide the solution
