I am having an issue when job is completed and the backflush checkbox is checked.
Looking at the on line help, it states that the materials will be backflushed from the input warehouse bin of the resource group if any on and quantity exists.
We don’t have stock in the input bin, so according to the help it should use the primary bin of the material.
Unfortunately, the system sees to use the input bin of the resource group, regardless of the on hand quantity, resulting in a lot of the input bins having a negative quantity.
Yes we had this issue. We used the same bin for input, output, and backflush. We were seeing everything pull from the bin defined in the backflush warehouse. When we removed the backflush warehouse (left it blank), it started pulling from the Part’s Primary Bin for that warehouse. We did this in both the resource group and the resource.
KB KB0112460 on EpicCare has the flow and rules for backflushing that I follow. the RG locations it will drive negative so we have a weekly true up of those locations.
