Messages in Background Processing

In background processing, all messages are handled in accordance with the type specified in the statement MESSAGE, with the following exception. Only during list processing is a message of type "W" converted into a message of type "E" before it is actually handled.

A message is not displayed, but instead is written as follows to the background processing log (job log) in accordance with the message type:

  • Messages of type "S" are written to the log and the program continues.
  • Messages of type "I" and "W" are written to the log and the program continues. The user input Enter, which is required to continue the program, is created automatically.
  • Messages of type "E" and "A" are written to the log. A check is then performed to see whether the message is handled using error_message. If this is not the case, the message is also written to the log with message number 564 of the message class 00 and current background processing is interrupted; here, a message of type "A" executes a database rollback and a message of type "E" does not. Background processing is resumed when the message is handled.

Other versions: 7.31 | 7.40 | 7.54


  • Since background jobs are always started internally using the statement SUBMIT, list processing is usually also active at the same time.

  • For messages of type "A", remember that handling using error_message causes the statement ROLLBACK WORK to be executed implicitly, hence producing a database rollback and other side-effects.
