Question for everyone. Is there a way to make an item commit from a sub-location to a sales order entered on the parent location? For example. I enter a sales order in WHS-6 location. There are no available quantity for an item there, but there are available quantity in WHS-6 : Repair Center (a sub-location of WHS-6). Is it possible to make the items in Repair Center automatically commit to the Sales order that was entered in WHS-6?

Not easily natively, I could envision it happening with Supply Allocation and a Transfer Order but that might be over complicating your process. Locations are all treated individually for quantities and counts, despite the financial piece rolling up.
