Re: where is perp_api?

>Permissions?

I observed that in table egw_acl there was no entries in aplication perp_api for locations curency, payment_method, shippers ...
On a test base I copied  the entry below from another base that works well:
aplication: perp_api
location:currency
account: -2
acl_rights: 15
and then the perp_api>>currency appeared and is working.
However, can you explain me what means exactly the acl right values: (1, 5, 15,...) because I don't understood so?
Can I repeat this for the other?
