Please enable the custom configuration for iRep Account Plan List.
It's confirmed from Ticket #441061. On the iRep Account Plan List view only display below:
1. Account Name
3. % Complete
Reason: It's compliance issue, we are not allowed to put free text on Account Plan. We modified the Name as auto number, and use a Pick list field as the Name. Now the iRep list is showing meaningless information which only showing auto number.
So please enable the custom configuration on iRep Account Plan List or at least showing a description (text field or a formula that we can control) after the Name field.
