User Access Settings Manual

Anybody have user security manual for AX 2012…

Technet: Set up user security in Microsoft Dynamics AX [AX 2012]

If you have a more specific question, you’ll have to write it down.

Thank you Mr.Martin…But do you have the step by step manual for this?

Step-by-step guides can be created only for specific tasks, not for completely generic concepts. You can have infinite number of tasks related to security, each of them with different steps. Therefore your question makes sense unless you come with a specific scenario.

just give me an idea, how to give permission to a user group …

Please read the documentation I already gave you. You’ll learn, among other things, that it’s based on user roles and not user groups.
