System admin cannot add or edit roles privileges duties Ax 2012

Problem:

Issue is user sys admin not able add or edit and roles privileges duties etc its allowing from AOT but not from AX client.

Solution:

If you have Sys Admin and Sys User you should be able to make changes via System administration > Setup > Security but if you are still not able to do that then there may be something setting issue.

After checking all setting at Ax found that Version control was enabled in the system so its not allowing to change roles privileges and duties  when Version control disabled then its working fine.

Due to Version control enabled its being locked for change and its for security reason.
