Query - How can we eliminate an already selected Item from the table displayed in a repeated Line? Solution - 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. 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.
