Error message: Security Manager is currently in use. Try again later.

Error:
Security Manager is currently in use. Try again later.

Cause:
Normally, only one user at a time can be in the Security Manager window, so when one user opens it, the window becomes locked to other users until the window closes properly.

You are getting this message because the Security Manager window did not close properly when previously opened.  Therefore, it is still left in a locked state.

Resolution:
For Versions 10.0 and later, follow these steps:
1.  Go to Microsoft Dynamics GP | Tools | Setup | Dynamics GP Toolbox | Dynamics GP Toolbox Setup.
2.  In the Setup tab, double-click Unlock Security Manager.

For Version 9.0, follow these steps:

1.  Go to Tools | Setup | Security Auditor | Security Auditor Setup.
2.  Choose System Settings and click Process. 
3.  Click Unlock.
