Hello,
In a record producer I have:
1. a "Location" variable, Reference type, to table cmn_location, for the user to select the location
2. a variable "Security officer", Reference type, to a custom table "u_location_so", to display the Security officer for the location selected in 1.
I thought I could do it with the Auto-Populate variable tab, in the following way: as the table u_location_so, has the columns:
- u_location, type Reference to table cmn_location
- u_type, type String (to identify the type of SE I need to display)
- u_so, type Reference to table sys_user
I created a variable "so_location" of type Reference with:
- reference to u_location_so
- reference qual condition: [Type][=][Security] /* to select the right type of security officer
- attributes: ref_ac_columns=u_location;u_so /* to display the location and the name of the security officer
- auto-populate: Dependent question: "Location", Dot walk path:Name /* to use the value Name of the cmn_location table to index the u_location_so table.
Unfortunately only the u_location column is displayed by the so_location variable.
Is there an explanation?
Is there a way to solve the problem and show the Name of the sys_user record referenced by the u_so column of the u_location_so table referenced by the variable?
I tried to add also a variable type Reference to sys_user and auto-populate from the so_location variable, but I couldn't make it work.
I have the impression (but don't know how to check) that for table u_location_so the "key column" is Created, insteal of Location or other, and this makes the auto-populate to not work as expected.
Thank you in advance
Flavio
