SAP Message O3 503 - Table MARD contains stock, changing the unit of measure group is not allowed

168 Views

Hi,

We have SAP IS OIL implemented in our systems. We had created a hydrocarbon material in Plant A and maintained Oil Specific Data tab in material master with relevant UOM group and Conversion Group. We had made stock posting on this plant and everything was working fine.

We extended this material to another plant B, but failed to maintain Oil Specific data in material master. Now when we try to maintain the same it gives following error:

Table MARD contains stock, changing the unit of measure group is not allowed

We tried to reverse the stock posting in Plant A, but no resolution. Does anyone face similar issue with IS Oil?
