Question

MRP creates an additional planned purchase order even though an actual purchase order already exists

Hi everyone,

We were having issue with the MRP,

We have two separate projects, and each project has one Production order. Both production orders use the same BOM and the same material item. Both Projects are configured with inventory tracking = Track by Project quantity and cost.

Scenario details:

Projects ID

Production Order Nbr

Start Date

BOM ID

Purchase Order

PROJ-VK-45

ORDER41326

5/11/26

BOM1

008815

JB-007

ORDER2

4/27/26

BOM1

 

 

Test steps:

  1. Created both production orders under two different projects.
  2. Since ORDER2 had the earlier start date, I placed ORDER2 on hold for testing purposes.
  3. Ran Regenerate Inventory Planning.
  4. Based on the demand from ORDER41326, the system created the supply suggestion, and we created a Purchase Order 008815
  5. Then I removed ORDER2 from hold
  6. Ran MRP again
  7. Reviewed Inventory Planning Results by Item.

Issue observed:

After the second MRP run, the system shows:

 

My concern is that an actual purchase order already exists for ORDER41326, but the system still generates an additional Planned supply instead of recognizing the existing purchase order as the correct supply.

Attached all relevant screenshots.

Any solution, guidance, clarification, or recommended workaround to prevent MRP from creating an extra planned purchase order when an actual purchase order already exists would be greatly appreciated.
