Re: where is perp_api?

The acl_rights value is the sum of the desired permissions, found in  
phpgwapi/inc/class.egw.inc.php, line 318-329
You could continue to manually edit the ACLs in this way, but there is  
a user interface.   In the Admin section, each projectERP application  
should have a "Configure Access Permissions" section.  Your time would  
be better spent trying to figure out what went wrong and why you  
cannot use this.  If you need to manually add permission, the location  
is 'acl'.

I don't use the Config access permissions because despite I am Admins, my access is not allowed.
Ok, thanks and regards.
