Hi Kevin,

I assume you are talking about the "work order" status showing as Waiting for components?

We use 2-step too and there are all sorts of interesting things that can happen.

If you have any validated manufacturing orders, where the picking operation was not completed, the quantity of components in pre-production will have gone into a negative. If you have a manufacturing order again for the same product, using the same components, and you complete the picking, all this will do is bring the quantity on hand in pre-production back to zero. 

For example, I have an MO to make 1 x plug assembly, the BOM has 1 x Plug & 1 x Cable. I can validate the MO without transferring stock (not correct, but possible). This puts pre-production to -1 Plug & -1 Cable.

Next MO i have for 1 x plug assembly, I complete the pick components transfer for 1 x Plug and 1 x Cable. This puts pre-production back to 0 x Plug and 0 x Cable. 

In this scenario, your MO would still show as Waiting for Components as there is no quantity of them in pre-production.

Another thing to check is on the miscellaneous tab of your BOM is the "manufacturing readiness" set to "When all components are available" or "When components for 1st operation are available"? 

If it is the former then all components on the MO must be picked and reserved before first operation shows as ready. 

If it is the latter then when the components are transferred that are to be consumed in the 1st op, it will show as "ready". If you do not state any components that are consumed in an operation then as soon as 1 component is picked, the WO will show as ready.

As the other poster stated, it would be worth checking the pick component transfer is being picked to (destination) Pre-Production, and also check the MO miscellaneous tab that the "component location" is also Pre-Production.
