Error fields appear in a batch-loaded record that you have selected for input or update.
Error messages are online responses to trouble with commands or searches.
Error codes For fixed fields, the error code is a solid block that appears to the left of the field that contains the error. For variable fields, error codes are two characters appearing to the left of the field that contains the error. When there is more than one error in a field, only one error code is shown at a time. When you update or derive from a record that has an error that RLIN has detected, you must correct the error before you can complete the transaction.
