Thanks Vijay for sharing the information. Could you please provide me more elaborate details. I was told that I have to be careful otherwise I could end up deleting all the groups or the users which need not to be removed from other groups. I am doing this for the first time so I don't want myself in an embarrassing situation by doing it incorrectly.
If you have any documentation for the same it would be really helpful.
Suppose I have 5 groups (Category Manager, Sales Contract Manager, Sourcing Approver, Internal Contract Manager, Sourcing Manager).
Now I want to remove 5 users 2 each from - Category Manager, Sales Contract Manager and 1 from Sourcing Manager. I don't want to delete this groups completely as I have other users which are aligned to these groups. So how should I do it.
I can see 3 options while I run User Group Map batch import that are 1) Update Only 2) Update Details & 3) Remove Details.
