Forecast not creating MRP demand for components

Hi Larry,

Check to see that your parent item has a default bill bill of materials for the warehouse the forecast is in. On the stock items check the manufacturing tab. Is there a BOM in the default BOM field?

You may also open the BOM for one of the parent parts to tests. On the ellipse menu select “set as Default BOM”. Be sure to select both Item and warehouse as defaults. Run MRP again.

Cwise,

Thanks so much for taking the time to reply!  The default Bill was set.  I set it again just to be sure.  I even set the BOM as the planning BOM even though I have never had to do that before.

Same results.

Forecast successfully creates demand for the finished part, but none of the component parts.

Everything is in the same warehouse.

I have spent hours trying to figure this out.  I would be thrilled to hear any more suggestions!

I’ve seen this before Larry. Try switching the checkbox on the forecast for dependent demand.

Chuck,

Thank you.  I tried but it did not resolve the issue.

Does anyone have any other suggestions?

Thanks!

Larry

Everyone,

Thank you for the suggestions.  I opened a support case on this and they suspect data corruption.

I do appreciate the suggestions!

Hi @ltussing03  were you able to find a solution? Thank you!

I stumbled upon a post by Lhouldsworth who found that if you define the replenishment source on the Item-Warehouse Details record, MRP will drill down and recommend the planned production orders and subsequent purchase orders. 

I tested this with a forecast, ran MRP and it worked well (for my specific client).
