Dave said -- Educate the PM is the answer! That's right.... Earlier i used to do lot of helps in an un authorized way(i have the DB scripts for updating / inserting collab mgr,participants) so i used to help(wrongly guide them) PM's.
the resaon is when we migrated from another tool to niku all the projects are created by admin (upload),so admin become the default CBM,even we changed the pm to the user
he still not got the rights,then we learnt that we need to do it manually, so we created the script and used it. Now strictly no for scripts,whenever the pm is leaving he needs to complete his activities in clarity.(Need to change the PM ,collab mgr to new pm or if the new pm is notidentified then need to add PMO as CBM). cheers,sundar
