Why is material on job tree showing as "Material needs attention," when there is quantity on hand?

Is the material onhand reserved/allocated for something else?

Gonna need more information. What does Time Phase show?

Are the materials on hand in the site / warehouse on the JobMtl?

We had the same issue and ended up customising it (in classic) based on the on hand quantity site-wide.

Thanks,

Nathan

Yes, materials on hand are in the site/warehouse on the JobMtl.
