How do you use the emcli create_cedential_set command? I'm having trouble understanding the documen

Hi,

I am trying to create a new metric extension to check data currency in a particular table.  When I test it I receive an insufficent privileges error.  I understand that I will need to create a new credential for the query to be run by a specific user.  On the metric extensions page it is noted that the emcli create_credention_set command needs to be run.

What do I need to set the parameters to if I want the sql to be run by the market_read user?

emcli create_named_credential
-cred_name=”name”
-auth_target_type=”auth type”
