Hi Ganesh,

1. Check the SLD connection

2. Test the JCO Connection

3. Test the BAPI is available in the R3 you are connected through SLD and test it working correctly.

For downloaded project, I rebuilt,acreated a new archive,deployed. There in WD Content administrator I have created JCos and working fine. Then I ran the appl, I got the above said error.

Hi Ganesh,

In the R3 system go to Transaction SE37 and give the BAPI Name and execute(F8)

Give the import parameters and execute(F8) and check the output

Kind Regards
