Combination rules are validated for the accounts that are entered in the “Budget year amount” window.

Generally, the Budget year amount window facilitates to add the values for each account in which the future transactions are planned. When an account is defined as illegal per user group in combination rules window, it says the accounts that are defined as illegal should not be allowed in postings in the system. Therefore, validating combination rules in the “Budget year amount” window is such that the accounts are planned not be used in any postings. That is the current functionality in the system. It assists not to add the postings for the said accounts (accounts that are defined as illegal in combination rules window) from the planning stage.
