Provision entries to be excluded from budge contorl

Hi,

We are on ECC6, EHp4, and already live 4 years back with SAP. Now, we want to exclude the provison entries from budget control. I understand,I can do the same by creating the new docment type. But in derivation rule the document type I see are the FM document type which are created for budget uplaod, am I correct?

How do I do this? Can anyone advise please.
