LSMW

I was Uploading materials in the check process of LSMW in the last step on error was coming can somebody tell me. Thanks

The field MARC-MTVFP is defined as a required field; it does not contain an entry

Message no. MG144

Procedure

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.
