stochastic block

[Former Member]

Hi experts

i am not clear with the documentation and example given with stochastic block.

Request please give me clear and detailed example, how it works? (how it differs to other blocks?)

The Stochastic Block is used at the time of financial crunch. It means not actually blocked but blocking the invoices only for checking.

The stochastic block is activated at the Co code level And we have to set the threshold value ( Cut off value ) & Degree of probability ( Percentage of total invoice thro' probability ).

Calculation is like this,

Threshold value is 1000 & degree of probability % is 20%, then

if the invice value is 100 then DOP is 20*100/1000 = 2%

1000 then DOP is 20*1000/1000 = 20%

1200 then DOP is 20* 1200/1000 = 24% but it treated as 20%

as per sap standard system.

so,if inv value is smaller than threshold value, the DOP decreases & if inv value is greater or same as the threshold value, then DOP is as same as the percentage entered.

If you want to select all the invoices with same DOP, then set the threshold value to zero.

This stochastic blocking process is applicable to whole invoice document not for the line item level.

Thank you friends

With 50% or 20% probability, how system chooses invoices for blocking?

What would be the influencing factor, to choose few invoices from the posted, say 20 invoices. (Here, howmany are blcoked and which are they?)

Hi,

In stochastic block ,you can block invoices at random to check them again. If the stochastic block is active and you post an invoice that is not subject to any other blocking reason, it can be randomly selected for blocking.

A stochastic block is not set at item level, but for the whole invoice. If a stochastic block is set when you post the invoice, the system automatically sets an R in the field Payment block in the document header data; there is no blocking indicator in the individual items.

Prerequisites

In Customizing for Invoice Verification, you can define:

If stochastic blocking is active

The degree of probability of a block. You set a threshold value and a percentage for this.

- If the value of the invoice is larger than or the same as the threshold value, the degree of probability that the invoice will be blocked is that of the percentage.

- If the value of the invoice is smaller than the threshold value, the degree of probability that the invoice will be blocked is calculated proportionally to the percentage.

If, for example, the threshold value is $100 and the percentage 50%, every invoice over $100 would have a 50% chance of being blocked; an invoice for $500 would have a 25% change of being blocked. If you want the degree of probability to be the same for all invoices, you set the threshold value to zero.

If you enter a threshold value of zero and a percentage of 99.9%, all invoices would then be blocked.
