Cost Allocation Account Type (CAAT) is the first window that you should update. It is an alternate window to Account Type (ACCT) which defines the various accounting values that are used during processing. This table allows you to define which of the account codes listed on Account Type (ACCT) are used in the cost allocation process, and how they are used. By defining which account types to use individually or combined, the appropriate General Ledger records are selected during the Build Cost Allocation General Ledger (CAGL) and Pool/Base Table Expansion (CAEX) processes.
