By lciking a button in the list applet, the status field(static picklist ) should be changed to another value in the puicklist.

i think this sicenario will be possible by using scripting
WebApplet_PreInvokeMethod(MethodName)
{
if(MethodName==Test)
{
var applet=this;
var bc= aplet.BusComp();
with(bc)
{
SetViewMode(AllView);
ClearToQuery();
SetSearhSpec("AccountStatus","Active");
ExecuteQuery();
var count=CountRecord();
var record=bc.FirstRecord();
}
while(record)
{
bc.SetfieldValue("AccountStatus","Inactive");
bc.WriteRecord();
record=bc.NextRecord();
}
return(CancelOperation);
}
return(ContinueOperation);
}

hi,

by using BC userprop we can achive this
BC usier prop: Named Method n
Value: "Method", "SET", "Status", "LookupValue(""TYPE VALUE"", ""XYZ"")"

Firstly you have must be idea about user property then u able to archive this.because user properties use for runtime changes in application. you write code there then must be given type and value pair must be given.
