I am getting below error during creation of Product Group MC84,
how to solve this
The field is defined as a required field; it does not contain an entry
Message no. MG144
Transfer a suitable value.
If the field is the material group or unit of weight, and the field is not ready for input, check whether the material is locked. If it is locked, you cannot extend the Purchasing view or the Sales view. If either of these views needs to be extended, the material must first be unlocked. This can be done only by a user with special authorization. Contact your system administrator.
For information on locking and unlocking material master records, see the SAP library documentation Material Master (LO-MD-MM) ->Locking Material Master Records.
