IN clause in ABAP dataflow

Hi All,

I have an ABAP dataflow which has below condition in where clause in query transform,

KNA1.KUNNR in ($G_CustNo)

I have tried setting global variable to following values.

$G_CustNo = 123,456,789

$G_CustNo = '123','456','789'

Still ABAP dataflow taken only first customer number into considertion. IN doesn't work. It works only like = operator for the first value.

Any idea how to resolve this?

Thanks in advance.
