Hi Bilab,
You can use Quoto arrangement functionality of SAP. In the material master MRP view maintain this materail as relevant for Quota, and using MEQ1 maintain the percentage of split for different production version in your case it will be 50-50%, once this is maintainted during MRP run the requirements would get split into different producion version. Please try the same and come back.
Also note please use the lot size which is activited for Spliting Quota in OMI4.
