When you create a material master record specifying a reference material and reference plant, the system proposes the production version(s) from the reference material. However, the production versions are adopted only after you have checked them by choosing ProdVersions .
The production versions are proposed only if the Propose field cont. indicator is set for the field MARC_MKAL. It is not set in the standard system. You can check whether this is the case in Customizing for the Material Master in Assign Fields to Field Selection Groups .
On the MRP , Work Scheduling , or Costing screen, choose ProdVersions .
The Production Version Overview dialog box appears.
Change the data as required and save your changes.
