For each dimension that you plan to use in the Financial Report Writer, you must have a complete COA cross-reference of type Separate. This step ensures the accounts are correctly translated when you generate reporting cubes.

The Financial Report Writer shares the COA Cross Reference records with the consolidation functionality. When the same charts are used in source and target, then you do not need to create COA cross references.

You can create a COA cross-reference of type Combined if you need a special mapping for combinations of GL accounts and sub-accounts or combinations of GL accounts and cost centers.

You only need to create COA cross-references of type Combined for exceptions. Financial Report Writer first checks if there is a COA cross-reference of type Combined for a particular accounting key. If a Combined map is found, Financial Report Writer uses that map. Otherwise, the Separate type mappings are used.
