MD04 Error - Conversion of unit of measure NOS to unit of measure ROL not possible

Hi all,

We are getting the mentioned error when executing md04 for a particular material. Material master is updated properly with UOM - ROL (roll).

Its a consumable material with manual ROP enabled. Stock fell below ROP but PR not generated. While checking in MD04 we are getting thi error.

Pl suggest how to solve this issue.
