Lower Tolerance Checking for PM Key

Question

Hi,
For our business process we accept every incoming quantity change made by the vendor in the purchase order response. We accept quantity increments as well as quantity descents. In order to prevent the POR from having to be approved/accepted by the responsible purchaser, we also need a lower limit to customize the same.
Therefore the question is, why is the lower limit input field missing in the PM key? When going through the help file of this customizing transaction we can read the following:
PM: Quantity variance (converted to currency amount)
If a confirmation is expected for a purchase order item, the system calculates the purchase order confirmation net price multiplied by the purchase order confirmation quantity. The system compares this sum with the defined upper and lower limits. You can also define percentage limits for the quantity variance check. Then the percentage variance from the expected quantity calculated - independent of the purchase order price - and this is compared with the defined percentage limits.
As you see above, it is clearly stated that u201CThe system compares this sum with the defined upper and lower limitsu201D. So according to SAP help, lower limit comparison should be possible.
In order for this to work we need the lower limit input fields.
---> Is there any other way to establish the above ?
Thanks and regards,
Aline

Hi,
Priority of tolerances is  PO tolerance limit,  TOG tolerance grp. for User, TOG tolerance grp. for Vendor (if user not logged on). Even absolute tolerance limit always has priority over percentage limit.
In your case, you need to check PO tolerance first then TOG for user.
