Summary:

We have a B application hierarchy which is getting updated from the MASTER application via Subscription marked as BLUE line. but within the same B application there is another set of members has to be created with PR_CCL_ * which has the same NT, and is currently manually maintained. So we wanted to automate this process marked as red. Is there any way we could trigger an alternate subscription to update the same ?
