Alternate UOM For indirect purchasing
It is possible to maintain alternative Unit of Measurement for indirect purchasing ie without material master?
Our issue is we need to receive Purchase Orders from SRM, where the Int UoM is different from R/3. Commercial unit and ISO Code are same. (R/3 - ZDI (Com SU, ISO: DI) and (SRM - SU(Com: SU, ISO: DI). While processing in SRM this throws an error what Internal UoM SU not maintained. As per our analysis, Int UoM must also be same in both SRM and R/3.
It is difficult to change UoM in R/3 as we have lot of PO's which are open and our landscape is huge.
One option we think might work if we can maintain alternative unit of measurement somewhere? Any ideas?
