Subcontracting requirements are not considered in long-term planning

In SAP standard the subcontracting requirements are not considered in the long-term planning.

In transaction MS04 the subcontracting dependent requirements are not displayed.
You can find further information in the SAP note 311336.

With an implementation of BAdI MD_CHANGE_MRP_DATA using method CONSIDER_RESB, it is possible to make the subcontracting requirements relevant for long-term planning.

Sample code:

*–> set flag to consider SC dep. requirements in LTP

       ch_no_exit_flags-ltp_subcon = ‘X’.

*–> set changed flag

       ch_changed = ‘X’.
