In the catalog variable there is variable name - user (*sys_user) and on the selection Cost Center

[jaiho_rai]

In catalog variable I have two variable 1: User 2- Cost Center

If I select the user auto populate the cost center.

I have used in the dictionary the variable "Auto Populate", it working in native on admin

if there if same thing I am checking in the portal it's not populating 

I tried to change the variable type from string to reference to (cmn_cost_Center) but that was not working .

I tried script, getReference via call back it was not working .

If there is a problem selecting a user, the cost center in the catalog variable is not automatically populated. Attempts to use the variable dictionary and change the variable type did not produce results. The getReference script via callback also didn't work. There are solutions: a more detailed study of the documentation or contacting a specialist, checking access rights and settings of the variable dictionary, as well as updating the system to possibly correct the problem.
