Since the Knierim system cannot process different groups of components having the same main part as pos. no. 12.1 or 12A, these groups require special handling. In such cases, use the option 25=Max+1 at positioning.

Thus you obtain different position numbers for such cases. The Knierim system will accept these numbers without any problem since they are handled as Z-parts. If you want all component groups to be handled as Z-parts, turn off the option ‘Transfer Mainpart Group’ and enter a start value for group positioning.
