How to pass values to a list collector from another list collector and remove when it removed.

[PHANI7]

Hello, 

I have two List collectors on different tables.

List collector 1 - Change Table - Referenced to Incident

List collector 2 - Incident Table - Referenced to Change

When List Collector 2 on Incident Table is updated with any Change Request, The Incident number should be added to the List collector 1 on Change Table. similarly When Change request is Removed from List Collector 2 on Incident Table, The Incident number should be removed from List collector 1 on Change Table. List Collector 2 can have multiple changes linked. So when any change request is mapped to multiple Incidents and unmapped from any one of the Incident, the current Incident should be unmapped from the that change request and the remaining incidents should remains added.

Can anyone help me out this thing. Thanks in advance.

What is the relation between VA and this question?

Why do you have the ability to link one Incident to multiple Changes? That doesn't really make sense from a process point of view. And what's wrong with the OOB related lists that just show which Incidents are related to that Change?
