Conditions type of category "Delivery Costs"(B) donu00B4t allow negative values
I would like to know if it is possible to munipulate a condition type with category "B" Delivery costs in such a way that it allows a negative entry in the Purchase Order.
Estandard SAP does not allow it. Message: 06259 "Negative Delivery costs are not allowed".
If the above is not possible, can anyone tell me how a can manipulate a Discount (fixed amount) in such a way that it not only points at a particlar account (accruels indicator does this job) upon MIGO, but also apears as a line-item upon receiving the invoice (MIRO). As far as I know, only Planned delivery costs can do this job. But they do not allow negative values!
If anyone has encountered a similar task, please tell me how they solved it.
