Hi all,


I am not familiar in PI Web Services and AF and would like to seek help here.


We have a vendor developed system which get AF attributes value by PI Web Services.

Below AF Path (sample) can be successfully retrieve value:


af:\\<AF Server>\<Database>\<Element1>\<Element2>\<Element3>|<Attribute1>


Below AF Path (sample) fail to retrieve value:

af:\\<AF Server>\<Database>\<Element1>\<Element2>\<Element3>|<Attribute1>|<Attribute2>


The version we are using is PI Web Services 2012 SP1.


Thanks all and looking forward to any hints.
