Stock levels and finances during Repair and Maintenance

We need to create a standard workflow for repairs and maintenance and need some help with the process. Our issue comes in when only certain parts are replaced and its impact on stock levels finances.

Example: A widget (heater) gets returned for repairs. We book it into our “Repair Warehouse”. Only certain parts (an element) will get replaced.

How do we manage our stock levels for only the replacement parts? Do we use a Stock Adjustment? Our primary concern in this matter is this: how do we get the replacement element to be deducted from our system?

Currently, we are struggling to figure out the necessary steps for this process during our workflow, using the Repair Warehouse for the repaired items and parts, and completing the process so that everything balances out.

Any suggestions?

Anyone with any suggestions? We have been battling with this for quite a while…
