Hi, we have a component on the work order that is source from PO, but it doesn’t use the cost from the PO, it uses whatever is set on the Item Record. THe Item is set up as a Service Item. How come it isn’t using the cost from the PO which was created from the Work Order, is there any way to make this work as desired to grab cost from PO versus the Item Record.

This is native functionality. The same happens with a special work order linked to a sales order. Either make a unique item for each special PO or investigate the custom gl lines plugin
