VCAT Difference in Phase

Hi All,

On a VCAT-enabled database, I recently updated the phase. When I simply saved the modifications in RUN_LOGIC and compared the results, something strange happened. which are listed below:

FAIL_MONITOR is likewise showing red, indicating that something has changed, but when opened, it revealed only a definition change difference, with no further changes visible in the difference.
The same is true for HOLD_LOGIC and ABORT_LOGIC, except for the definition.

Does anyone have any clue what caused this change? I've done modifications before and moved them from development to qualified environment, but I've never seen anything like this.

Thank you in advance.

  Embedded composites in a module are named internal to DeltaV with a name that is automatically generated based on the time stamp.
  They will generally change names when you make and change and save the module. This allows for phases, module classes, etc to be downloaded and only affect the particular instances that were downloaded and leave the modules that were not downloaded unchanged until ready to be downloaded. I suspect that what you are seeing is the reflection of a new composite name.

  In reply to Matt Forbis:

  It's not necessarily about the name of an embedded composite. You can only edit those embedded composites by editing the phase, so you'd get to see the differences right away. Things get tricky when you have linked composites in a phase. The linked composite you can edit independently of the phase, it won't force you to check out the phase itself. However, the way the phase VCAT compare works is it will show you all differences in all composites. So when the phase goes to the next version for an unrelated change, you will also see the linked composite changes in this new version when you do the compare.
