I need to remove the code changes of an activity from the child stream, which is shared among two projects. Wanted to remove code changes from Project A but I need to secure not to lose the changes in Project B

Can someone suggest me the possible solution and the next steps to be taken care to get rid of this issue.

    Do a negative merge as in https://stackoverflow.com/a/1637405/6309: I'll put an answer in a few hours. You can apply that to an activity change set: https://stackoverflow.com/a/8049738/6309 – VonC Aug 17 '17 at 06:44
  • But activity is already delivered in project A....So we can not perform merge operation on delivered activities .... – Rajendra Aug 17 '17 at 12:04
  • It does not matter: you create a *new* activity which will contain a negative merge of the existnig activity change set. – VonC Aug 17 '17 at 12:04

See "Reverse Change set of an activity in Clearcase": you can use ccperl cset.pl -undo, or do for each file in an activity a negative or subtractive merge.

In both case, the goal is to create a new activity whose change set will represent the negative image of the existing activity.
You can then do what you want/need with it, like deliver it to another stream where the first activity was already delivered.
