MRP tries to split components of project order

(0) ShareShare

Posted on by 5

Dear community,

we have the following setup:

Product A: Replenishment (Production Order), Manufacturing Policy (Make-To-Order), Reordering Policy (Order), Order Tracking Policy (Tracking Only)

Product B: Replenishment (Production Order), Manufacturing Policy (Make-To-Order), Reordering Policy (Order), Order Tracking Policy (Tracking Only)

Product C: Replenishment (Production Order), Manufacturing Policy (Make-To-Order), Reordering Policy (Lot-for-Lot), Order Tracking Policy (Tracking Only)

Product A and Product B both have a BOM and also a routing. Both products use product C as a component with the quantity of 2.

Then, we create a sales order. This sales order sells product A with a quantity of 1 and product b with a quantity of 1 (sales order with two sales lines). Then, from this sales order we create the necessary firm planned production order  (project order). The production order is created and has three lines. Product A with a quantity of 1, product B with a quantity of 1 and product c (visually intended because of make-to-order) with a quantity of 4. So good so far. This seems all good.

However, if we are running the MRP, Business Central tries to change the quantity of product C of the existing production order. It wants to reduce the quantity by one. What is more, it wants to create an additional production order with a quantity of one of product c. 

We did not expect this behaviour. In our old Navision system, we did not observe this behaviour.

Can somebody explain this behaviour?

Thank you very much!

Best regards

    You will likely need to reach out to your partner for support.  Data plays such a critical role in the MRP calculation, and without seeing everything it would be really hard to identify why you are getting the suggestions you are receiving.
