Hello,
This is not possible in standard SAP if you used Individual/coll. = 1 Individual requirement.
System will generate the planned orders for every individual sales order line item.
If you used Individual/coll. = 2 collective requirement with lot size as EX system will generate the planned orders for all the requirement on the day. Please test with Individual/coll. = 2 collective requirement with lot size as EX
Best Regards,
