Partial Operations

When named elements are specified in an ISSUE, DROP or FLUSH command, it is known as a partial issue, drop or flush. There are some restrictions on what the user can do, as follows:

• Where a non-primary element has changed owner, then the old primary owner and the new primary owner must both be issued back at the same time. Otherwise there is potential for inconsistencies to occur.

• If an element has been unnamed, and the name reused, then both elements must be flushed back together.

• If an element and its owner have been created, then:

  • If the element is included in a partial flush, then its owner must also be included.

  • If the owner is included in a partial drop, then the element itself must be included.

• If an element and its owner have been deleted then :

  • If the element is included in a partial drop, then its owner must also be included.

  • If the owner is included in a partial flush, then the element itself must be included.

The HIERARCHY option will scan elements in both the extract and owned extract. Thus deleted/moved elements will be included as part of the issue/drop/flush.

The user can use selection criteria to specify partial issues and flushes.

Deleted elements will be issued/dropped/flushed when the owning element is issued/dropped/flushed. Alternatively the reference number of the deleted element may be given in the ISSUE/DROP/FLUSH command.
