The SAP error message FI692 ("Commitment item must not be changed in FM area") typically occurs in the context of Funds Management (FM) when there is an attempt to change a commitment item in a financial document that is not allowed due to the configuration or the status of the document.
Cause:
Configuration Restrictions: The commitment item is linked to specific settings in the Funds Management module. If the configuration does not allow changes to certain commitment items after they have been posted, this error will occur.
