I am struggling to understand how to proceed with an issue I am trying to resolve. I have a page that is based around creating and maintaining an issue log. There is a repeating group if issue logs and the ability to create a new one. When I create a new issue log I populate a field with a value that comes from another table by using DoSearch to get the last sequence number for this location which I then increment by one.
The issue I have when I create the issue log I also want to be able to write the new sequence number back to the Locations table but this is not available to me when I use Make Changes to Thing.
What do I need to do to make this thing available for update?
