Nullify the quantity values in cost center Report

Dear Experts,

We are booking the cost in the cost center for production related expenses.

Activity quantities updating in the cost center report based on the PO Confirmations.

Our objective is to track the operation quantity related to that particular cost center for the distribution of cost from General cost centers to the relevant cost centers, to get this we have created the SKF and linked the SKF to LIS Tables.

Then Linked the SKF to the cost center in KVA2 and when we run the KVA5 quantities were updated perfectly from LIS table.

Query:

Quantities updated for one period and cost apportioned based on that quantity.

We found that the quantity used as a base for distribution appears to be wrong. so we need to replace or empty the SKF quantity in cost center report.

How to nullify the skf quantity in cost center report.

Thanks.
