SIGN='I',

OPTION='CP',

MATNR_LOW=*. It is working properly.I t had displayed all the materials. I have another web service "authenticate". I have connected the output port of "authenticate" web service to input port of "InputForm". After making the connection,it is showing error like

"An eror was returned from the back-end system:[HV] valuein field SIGN can only be I,E". Even i have tried with I and E both. Please help me out.
