Creating revisions using the Extend option - example

The old routing or BOM has operations 10 and 20. Operation 10 has sequences 10/1, 10/2, and 10/3. Operation 20 has sequences 20/1, 20/2, and 20/3.

This diagram displays the old operation sequences and the revisions and operations created from them using the Extended option in the Generate Job Shop Routings (tirou4200m100) session or the Generate Production and Job Shop Bills of Material (tibom3200m400) session.

In the diagram, the upper two bars represent the operation sequences. The subsequent bars represent the resulting revisions and operations.

The date specified in the Create From field is the effective date of the first revision, 001.

In the diagram, the expiry date of an operation sequence is the same as the effective date of the next operation sequence. Thus, the expiry date of 10/1 is identical to the effective date of 10/2.

Consequently, one revision is created for the expiry date of 10/1 and the effective date of 10/2, another revision for the expiry date of 20/2 and the effective date of 20/3, and so on.

The first revision is 001. The effective date of the first revision equals the date specified in the Create From field. Revision 001 ends where the next revision, 002 starts. The effective date of revision 003 marks the expiry of 002.

Revision 004 partly parallels 003. This is because revision 004 is not yet approved. When 004 receives the Approved status, the effective date of 004 will mark the expiry of revision 003.

Typically, the expiry date of the last BOM or operation sequence is set to the maximum date of 12/31/9999.

Because each routing has two operations, 10 and 20, the new revisions have two operations.
