Thanks Leo, but unfortunately I don't think that's the issue for a couple reasons.
1) We have hundreds of other items that have cs(case) as the designated BOM unit with no issue.
2) in many instances the units/case is different. So, I would need to set up several, if not dozens, of case to units conversions leading the system to much confusion on which one to reference.
Thanks for your suggestion, but I'm still thinking there is a parameter that was auto set when the BOM unit Each was selected that is in the background that I am unaware of.
