See the graphic depicting this baseline logic below.
After approval of the baseline schedule and the start of updating the project schedules, the project’s logic can always change depending on what is being installed in the field.
How to update the existing records with sequecely or random unique data? How you do this depends on what is involved in populating the values.
After whichever method you use, add an unique constraint on the column to ensure data integrity.
To check for out-of-sequence progress in an updated schedule you can do the following.
In the first example, activity 110ERI2131 is an activity in the report above that has out of sequence progress that needs to be addressed. To see why the issue is occurring, the original logic must be understood.
In the baseline schedule the original logic was set up as Install Lighting Conduit Columns 7-15 and was to be installed before the Lighting Conduit Columns 15-21 as a Finish-to-Start relationship.

There is a Log to File function that creates a summary level report from the current project.
