column expression, not contains

Dear all,

I have a column expressxion with an complex if statement:

if

(

(left(column(“SerialNo”),3 ) == “111”) &&

(contains(upperCase(column(“ObjectSubEquipmentDescription”)), “1K/2C”)) &&

(contains(upperCase(column(“ObjectDescription”)), “2XCOMP”))

)

{

replace(column(“ObjectDescription”),“1xCOMP” ,“2xCOMP” )

}

else

{

column(“ObjectSubEquipmentDescription”)

}

How do I have to write does not contains instead of contain in the last expression of if statement?

(contains(upperCase(column(“ObjectDescription”)), “2XCOMP”))

like

(not contains(upperCase(column(“ObjectDescription”)), “2XCOMP”))

Thx for help!

BR,

Heinz
