Using Java Connector Calling RFC.....But it's not returning correct result

[Former Member]

Hi Friends,

In the code ....

I am calling Remote Function module ZRFC_PO_VEND_VALID using java connector and passing PO_Number and Vendor Number as input parameters and after execution it returns (E_POVALID =1 [PO_NUMBER exists for Vendor number] otherwise E_POVALID = 0 )

when i am executing the below code ....in both cases it is returning Zero value.

I tested the function module in se37 its working....

may i know the reason for this....

import com.sap.mw.jco.*;

Try padding the vendor number with leading zeroes(Total length 10).

<b>vendID.setValue("0000020081");</b>
