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 R/3 System. You can check whether this is the case in Customizing for the Material Master in Assign Fields to Field Selection Groups.
