Neither DS or PS should be accessed by anyone other than the PM. Inventory increases or decreases should only occur through receipting, invoicing, repair orders or MSR(manufacturer returns).
The frequency with which it is necessary should be minimal. I use DS to adjust for things that would not warrant receipts, such as OP, a generic number for the cost difference on warranty repair orders for parts obtained where GM will reimburse added cost. Also for EXCHANGE, another generic part number for radio, cluster exchange allowance. The OH is usually zero, so it goes to a negative OH. Zero cost as a generic number.
Other than examples like that, when all parts personnel have access to those functions, you will DEFINITELY end up with never ending discrepancies in your inventory. Employees with less concerns for inventory accuracy will indiscriminately make adjustments without ever inquiring as to why there is a discrepancy.
Figured this out 20 years ago and told the office manager to TURN OFF both DS and PS for anyone not responsible enough to care. Had a lot of push back from counter personnel originally, but I realized they didn’t understand ALL of the ramifications of using these functions.
RPM (Report Plus/Minus) can be run monthly to review any manual adjustments made through these functions. The monthly value of these adjustments also TOTALS in the MGR Report if anyone is monitoring. Ideally the value should be as near to zero as possible. If it’s excessive, you have a problem.
