This error happens when you are working on a bran new installation of SAP. Although this is a MM Consultant’s job, students of SAP SD Training will also need to know this in case of system resets. This happens during all material movements ( specifically PGIs, stock inputs etc as relevant for SD Consultant ) and should be corrected ASAP. The solution lies in adding new number ranges for specific transaction types in OMBT. This could also be useful for other SAP Training students as well who are stuck with issues related to material movements. Another related post on closing material posting periods ( MMPV ) can be seen here.
Step 1 : Go to tcode [ OMBT ] and click on “Groups”
