When you select a record it would be great to see the linkages in a graphical format rather than line entries with some form of hierarchy understanding between master agreement and sub-agreements where relevant with capability to click select each record. When creating links there may be a requirement to build some logic rules. I will do some analysis and add examples in a file when I have time to better illustrate current and potential .

Logic
1.Link contract records for master and sub-agreements with logic such as when you create a sub-agreement from a master agreement or link a sub-agreement to a master agreement, the master agreement cannot be expired.
2. You must specify the expiration date for a sub-agreement to be before or on the same day as the expiration date for the master agreement.
