Although I have never run this process, my poreqdet, poreqhist, poalloc and purorddet combine to 12+GB. A number of the purchasing queries and process manager planning after a receipt or after updating purchase orders are a bit on the slow side. I ran profiler and found that the following stored procs are slow: AutoPO_Plan_FixedPOSOOpen and ADG_Plan_FixedPOSOOpen.
I suspect that the delete purchase orders process would improve performance. Prior to running this process, I would like to know if it moves the data to an "old/archive" table or if it actually deletes the records.
Thanks
Steve
