I have a window tab based on a table that has a foreign key reference to AD_User via ad_user_id. In Tables and Columns this column is given a 'Search' Reference with AD_User as the Reference Key.
When I open the tab with the ad_user_id field the search icon (green arrow) is displayed in the field for the user id but when the lookup is performed only the GardenAdmin logged on user, the one creating the record, is available to select. There are six users defined for GardenWorld, all of which are active.
What else needs to be done to get all the availible users on the selection list?
You can try setting -1 as the default for that new AD_User_ID field.
In iDempiere fields take defaults from different sources:
Note the order to get the defaults can be differently managed via the System Configurator key ZK_SEQ_DEFAULT_VALUE_PANEL
