This function can be used only for the material master for industry, not for the material master for retail. You use it to define which fields in the material master are lock-relevant. If a material is locked in material master maintenance, the fields flagged in this activity as lock-relevant can no longer be changed.
In test systems, you can set fields flagged as lock-relevant to non-lock-relevant at any time. You do this by cancelling the Lock-relevant indicator. In production systems, you can do this only if there are no locked materials in the system. If locked materials already exist, you can only flag further fields as lock-relevant.
If you flag a field as lock-relevant, and changes have already been scheduled for this field in a locked material master record, the scheduled changes are lost.
For a quick overview, you can restrict the fields displayed in this activity to those you have already flagged as lock-relevant. Alternatively, you can display only fields that are not flagged as lock-relevant, or you can display both.
No fields are flagged as lock-relevant in the standard system.
