Siebel escript: How to exclude a field in GetSearchExpr method.

Hi All,

I want to exclude a field value from GetSearchExpr method.

I have fields A, B and C exposed in a form applet. In BC pre-query, I need to modify the searchexpression before executing the query. In BC Pre-Query I am dong the modification of search expression using SetSearchExpr = GetSearchExpr + logic.

Here I want to exclude value of field C returned in the GetSearchExpr. Could you please help how to achieve this? I cannot combine GetSearchspec [A] + GetSearchspec [B] because in future fields might get extended and need to edit the code then.

Thanks!
