Execution Sequence

After you have entered the appropriate parameters for System Copy GT, the job should be started as a background job with a variant. The execution sequence is as follows:

1. Creation of “intervals” that represent the work to be processed
2. Processing of “special objects” of type A (prior to conversion of core tables)
3. Main parallel processing of updates to logical system fields
4. Processing of “special objects” of types TXZ (after conversion of core tables)
5. Collation of results for viewing of what has been done
6. Display of output (ad-hoc)

Steps 1 and 3 are able to be completed using Diffuser to utilize multiple processors. The remainder of the steps in the above sequence are done in a sequential manner with a single work process.
