How to fix this error?

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 <LS>Purchasing</> view or the <LS>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.
