# Tolerance Limit

Dear All,

I have used t-code OMR6 & assign tolerance key PP with Lower value 10- & upper value 10+. when i run t-code MIRO that time system will accept only for Credit not for Debit value.

Second thing After MIRO when i run Sub DR or Cr it is not working.

please guide me.

Regards

Please Maintain Tolerance Limits PP & PS in OMR6

and Please Go thru the Below Explanation of Tolerance Key PP :

**PP: Price variance**

The system determines by how much each invoice item varies from the product of quantity invoiced * order price. It then compares the variance with the upper and lower limits defined (absolute limits and percentage limits).

When posting a subsequent debit/credit, the system first checks if a price check has been defined for subsequent debits/credits. If so, the system calculates the difference between (value of subsequent debit/credit + value invoiced so far) / quantity invoiced so far * quantity to be debited/credited and the product of the quantity to be debited/credited * order price and compares this with the upper and lower tolerance limits (absolute limits and percentage limits).

**PS: Price variance: estimated price**

If the price in an order item is marked as an estimated price, for this item, the system calculates the difference between the invoice value and the product of quantity invoiced * order price and compares the variance with the upper and lower tolerance limits defined (absolute limits and percentage limits).

When posting a subsequent debit/credit, the system first checks whether a price check has been defined for subsequent debits/credits, If so, the system calculates the difference between (value of subsequent debit/credit + value invoiced so far) / quantity invoiced so far * quantity to be debited/credited and the product quantity to be debited/credited * order price. It then compares the variance with the upper and lower tolerance limits defined (absolute limits and percentage limits).
