To eliminate an already selected Item from the Table, one needs to disable the Field Attribute Common Table. Also, the Collection Attribute Unique must contain the UDF being stored in the target Field.
For example :
[Field: Unique Item Fld]
Use: Short Name Field
Table: CollOfStockGrp
Storage: Unique Item UDF
Common Table: No
[Table: CollOfStockGrp]
Type: Stock Group
Fetch: Name
Format: $Name, 20
Unique: $Name, $UniqueItemUDF
In the above Field Unique Item Fld, once any Item from the Table is selected in the previous Lines, the same will not appear in the list subsequently.
Note: Field Attribute Storage is mandatory to get unique Items in the List. In the absence of Field Attribute Storage, the above will not work.
