I like to know why delivery charges cannot be settled via ERS?
Please help me understand.
I like to know why delivery charges cannot be settled via ERS? Planned or unplanned.
Unfortunately that was just the way SAP had designed the ERS functionality around planned delivery charges upto version ECC 5.0. However, this functionality is available from version ECC 6.0 onwards.
I had done an 6.0 upgrade assessment a while back and I noted that there is a new check box on the MRRL selection screen for settling planned delivery costs in addition to goods and service items; there is a new transaction MRDC for settling only planned delivery costs with freight vendors; and there is new config node for ERS planned delivery cost settlement activation (SPRO->MM->LIV->ERS->Specify automatic settlement of planned delivery costs).
So if you are on a version below 6.0, then you will just have to live with this limitation or design your own custom program for ERS planned delivery costs settlement.
Hope this helps.
