Multibox object to select first value in alphabetic order(A-Z) of TEXT strings

[aj0031724]

DEAR TEAM,

We have one multibox object which is subset  of FEILD (KPI).Here multibox object will show values excluding selection of MAIN KPI.

Example:

KPI Values->A,B,C,D,E,F,G

Current Selection of KPI -> A,B

THEN MULTIBOX OBJECT WILL CONATINS-> C,D,E,F,G for user selection exclude (A,B).

What clients require is that in Multibox obect drop down it should be autoselected with  first value in alphabetic order(A-Z) list.

i:e here Multibox object selection will be "C"" of KPI as it is the first that appears in aplhabtic order.

Is it possible that I can do as required by any MACRO or existing QLIKVIEW TRIGGERS? CAN YOU PLEASE ADVISE.
