In addition to Blog by Mr Rajen http://scn.sap.com/community/erp/manufacturing-pp/blog/2013/08/15/alternative-bom-selection-a-workaround,

The Alternate BOM  selection method based on the MRP 4 which determines the selection of alternative BOM in MRP run.

Selection methods which are available are as follows:

which are explained as follows from( F1 help):
  • With Selection by order quantity, the system chooses the alternative BOM into whose lot size range the order quantity falls. The lot size range and area of validity of the BOM apply.
  • With Selection by explosion date, the system chooses the alternative BOM into whose area of validity the date falls according to the setting BOM via dates.
  • With Selection by Production version, the system chooses the alternative BOM defined in the valid production version. The lot size range and area of validity of the production version apply.
  • With Selection only by production version, the system chooses the alternative BOM defined in the valid production version. The lot size range and area of validity of the production version apply. If no production version is found, no production orders or process orders can be created.
Then Followed  production version assignment in Planned independent requirement  MD61 in schedules lines we can directly generated procurement proposals with required Production version, But in case in order to assign more than one production version on the same date system will not allow to do the same, which can be done my changing the Version in Schedule line Tab in MD61

Then system will allow to assign different PV and will show in MD04 as follows:

Two different planned orders can only be created on the same day if requirement belongs to different segments like project sales etc. SAP will cumulate the requirement for single date in General MRP ,even as Lot size is EX .
This can also be taken care through Quota arrangement in MEQ1 also for inhouse produced material and provided that the lot size procedure assigned to material is having splitting check box in customising of Lot size procedures OMI4.

which means the lot is split up in planning run.

    Hi Anupam,

    I would like to add one point, we have seen threads that ‘the production version column is grayed out in MD61/ MD62’, can you kindly add that part? (MD61 -> Schedule Lines tab -> Settings -> Production Version).

    Another request would be to change the name to ‘Rajen’ from ‘Rajesh’ for the mentioned blog post. 😀

    Best Regards,

    Rajen
