Hi,

Make sure that the JCO you are using is working fine.

Check that the userid and password is still valid.

Hi Ankit,

Check whether the RFC is working fine or any changes happened? Log in with the user same as portal and then execute the RFC. The problem seems to be from RFC.

Hello Vaish & Ankit,

Can you check what is the dump occurred in transaction ST22?

I hope you guys are working with HR data. So, i think some object is not passed(internally) correctly in RFC.

Please debug the RFC by keeping the breakpoint from webdynpro application, then you will come to know what is not passed when we execute the RFC from R/3.
