Currenty end user has below requirement , but I have no idea. So i need some advices.

• Item A (manufacturing item), Fixed lot qty = 10,
• In such a case, MRP creates a planned order as multipes of 10.
• User want this planned order to be created 5pc and 5pc automaticaly.

The material item (buy item) lot is smaller than Item A and supplier can not deliver a lot of materials at once which means can not follow manufactuing lot.

But manufatuing department want to keep manufacutring lot(In -house operataion).
