Steps

  1. Open Accounting → Setup and Posting rules.

  2. Create a new rule or choose Edit on the intended rule. Select the module and source type, then specify item type and cost centre when the mapping needs those restrictions.

  3. Select the debit and credit accounts, set priority and active state, and enter a description or finance note.

  4. Save the rule and check it in the rule list. Use the active-state control to disable an obsolete rule; review the resulting mappings before relying on later postings.
