RFDKLI20 - item quantity confirmation

Dear all,

we are using credit management in SAP. Customer credit data are maintained in transaction FD32. In case that risk category is changed, report RFDKLI20 (transaction F.28 is adviced to run). Because of change of risk category I need system to change open documents (using option "Recreate FI and SD data"). In help is written that internal VA02 is used for this and should happen the same when VA02 was run. And here comes the problem. If I have a sales order with unconfirmed quantity (on purpose) of material (on stock is sufficient quantity), in standard VA02 transaction nothing happens. I run it, save the sales order. If I do not run "Item availability" check manually in VA02, material remains unconfirmed. But when run RFDKLI20, system CONFIRMS material quantity. I do not want this function. Is there any customizing for this? Or is it a "feature"?

Please, help me with this, because for us this is not a requested behaviour.

Thank you

David
