In Post General Journal Entries, this is a required field for some accounts but I want it optional
Whether this field is required or optional is determined by the account group.
It's not possible to edit SAP-delivered account groups so please create your own using 'Copy as' in SSCUI 103508 'Define Account Groups'. Select your newly created account group and choose 'Field Status'. Under 'Bank/Financial Details', this field can be found and changed from Required to Optional.
All accounts that this account group is assigned to will now have this field as optional
