Physical is a special thing, and shouldn’t necessarily be done twice a month, let alone more than once per year… Maybe, we’re confusing things here and they are doing “Cycle Counts” more than once per month - which would be perfectly normal.
My hypothesis still stands though - a part can only be on one cycle at a time. I would go through the cycles and see if you can find the open/incomplete one and cancel or delete it.
You should be able to find your open cycle counts using CC Maintenance and searching. I would used a variation of these two checkboxes just to be sure (unchecked, both checked, each checked)…
