@Hally In my experience, it is typical that the ERP system must allow inventory to go negative in order to backflush. The concept of “Negative Inventory” is an imaginary construct. If the part was built using all of the correct components, they had to come from somewhere. Often the root cause is a missed receipt, duplicate part numbers for the same physical part used in MoMs but only one is inventoried causing the others to go negative, or an inventory job that was physically completed, but not processed in the ERP system. The list goes on. What I had in my last system that I don’t find here is a Backflush Location. It allowed us to backflush the same part from different locations based on the MoM which often defined where the assembly was being built. It meant that one had to diligently manage Inventory Transfers to the various Warehouse Bins (Backflush Locations) to avoid negative on hand.
If E10 has that functionality OoB, please let me know.
There’s a help doc that explains the hierarchy of where things will get backflushed from. I believe it’s accurate, but I would definitely test it, as I’ve seen issues with it in the past (Might be interpretation or bugs, I don’t remember)
One of the things you can set is a in/out bin based on resource group. So this would relate to your operations that you have set up. So it sort of follows the MOM.
Regarding the hierarchy, in 10.2.400, #2 and #3 indicate it will not backflush from those locations if inadequate quantity exists. This is not true, it will take you negative.
backflush location can be defined based on the OPERATION’s chosen resource or resource group.
so…
Material is tied to an OPERATION
Operation is tied to a RESOURCE GROUP/RESOURCE/CAPABILITY (AKA RESOURCE)
Resource is tied to a backflush location.
The idea is that when you start the operation, you can choose which resource you are running from, which then specifies where you will backflush the material from.
Tim, I’m trying to prove a point to my boss, the owner of the company, that we should/do need operations. BUT we do not track time in Epicor. That is done through another software that our IT dept built/created.
In that case, just use the operation @mhunt ! There are more benefits than not. You don’t have to track time with them, but they do help in other ways to just report them.
