resource—the “Cut Neck Post” operation. Move it to the right and note the change in the
window. A plus “+” sign appears in front of the Warning entry. Expand this and you will
see the message shown next.
If you perform a check, Adjust > Check Sequence, it will tell you that Validation is
required for one operation, and it suggests that you check the log messages for more
details. If you check the log, it will tell you that the operation “Machine Neck Post”
operation, Operation 20, is out of sequence (as shown below).
You can avoid the need to perform the check by selecting the Adjust > Validate Op On
Drop menu option. This causes FactoryTalk Scheduler to check automatically for
sequence constraints whenever you drag-and-drop an operation, and any problems will be
written to the log. You can clear this log file at any time by selecting the Edit > Clear Log
menu option. If you violate a sequence constraint and want FactoryTalk Scheduler to
accept the position of the moved operation, you can select the Adjust > Forward menu
option. This moves all affected operations to a position where the sequence constraints are
valid. Note that none of these actions consider other constraints; e.g., materials, additional
resources, or special constraints.
