Interchange the debit credit G/L entry for MIRO
In my company, we have set the planned delivery cost as condition types for normal PO's (eg: freight in %). So during MIRO INV, the G/L entry will be debit for the accrual acc.
However, we would like to create Return PO for return materials, so we will have to credit back the planned delivery cost we have payed for the vendor (eg: freight in %). During the creation of Return PO, we cannot set the condition type as -ve (error msg: Negative delivery costs not allowed). This causes, during creation of MIRO credit memo, the acc entry wrong (still debit the accrual acc, it should be credit). We don't want the delivery cost to be put in manually. We want it to be automatic from Returned PO condition type (for security reason).
