Group and Record Processing (Magic xpa 4.x)

Group Processing

1. The first record is fetched into memory.

2. If the Evaluate condition task property is set to Before entering record, the End Task condition is checked.

3. The Exit action is checked, whether or not the user has pressed ESC.

4. The Group Prefix logic unit operations are executed for the first task cycle and whenever the Group logic unit's variable value is different from the previous record value.

Record Processing

1. The Record Prefix logic unit operations are executed.

2. The Record Suffix logic unit operations are executed.

3. The record is saved with the new values. If the Task mode is set to Delete, the record is deleted.

End Group Processing

• When a new record is fetched and the Group logic unit's variable value has changed, the Group Suffix logic unit operations are executed for the previous record and the Group Prefix logic unit operations are executed for the current record.
