# Invoice block due to tolerance limit

Hello,

I have created a PO for 600 DKK.

I have created an invoice for 610 DKK and want to do the invoice verification in MIRO.

The invoice gets blocked.

Which tolerance limit is causing this?

I have specified tolerance limits in transaction OMR6:

1) PP (price variance): + 5% - 5% +15 DKK - 15 DKK

2) KW (Var. from condition): +2% -2/ - -

My 10 DKK difference between the PO & invoice lies between these tolerances.

Are there any other tolerances to be fixed?

Thank you for sharing your experience.

Kind regards,

Linda

Hi,

Stochastically blocked meaning that the invoice was blocked due to a payment block set at random in the document header. For each company code, we can define the degree of probability that an invoice will be stochastically blocked. In IMG setting, We mention Threshold value and the Percentage probability for our Company code.

The degree of probability depends on the invoice value. If our Invoice value is the same or larger than the threshold value, the degree of probability is the same as the percentage probability maitained. If the invoice value is smaller, the degree of probability is calculated in proportion to the threshold value.

Example

Threshold value: 3000 percentage: 60

Invoice value Degree of probability of a block

3000 60 %

5000 60 %

1500 30 % (= 60 * 1500/3000)

100 2 % (= 60 * 100/3000)
