While I was working at the customer site for BPC NW 7.5 for implementing BPC secutiry, I found 'BPC Mass User Management Tool' doesn't support deleting functions!
So I asked a question to customer and she said she had to delete user, profiles and teams one by one using BPC admin console......
In addition, at the same time, one of my colleague asked same question to me so I decided to enhance it.
I am not an expert ABAP developer but thanks to my development experience with other programming language, I could enhance it.
After I made it, I tried to make it as a transport file but I gave up because it may trigger maintenance issue.
If a lot of BPC administrators / consultants need this tool, I will post it later including document so please leave a comment.
