Hi
When trying to create the article master i am geeting this error. I have checked in customizing there is no field lock and it can not be set as optional because for this site MRP required.
Details of error
The field RP Type is defined as a required field; it does not contain an entry
entry
Message no. MG144
Procedure
Tansfer 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.
Note
For information on locking and unlocking material master records, see
the SAP library documentation Material Master (LO-MD-MM) -> Locking
Material Master Records.
