Issue in MRP run and creation of planned orders

Hi

We have a requirement , need guidance to map the scenario.

Scenario:   Production batch sizes (Lot size) are fixed Max. 200 and Min. 50.

In materials MRP1 view we had maintained Lot size as EX and Max. and Min. lot sizes as 200 and 50.

Planning is done using MRP for the product for 950 units.

Issue: After MRP run 4 planned orders are generated for max. lot size 200 units which equals 800 units, remaining qty. is 150 and min. lot size is 50 units. For remaining 150 units one planned order is getting generated for 150 units.

The requirement is to generate the 3 separate planned orders for 50 units each.  

Regards
