User has no RFC authorization for function group.

Hi expert,

I am calling a new function module  from the WebDynpro Java that is causing an issue that User has no RFC authorization for function group. if the user doesn’t have proper authorization like SE37 Transactions Code and others.

But there is some more existing function module in the same application that is working fine without having above issues with same access.

I am passing the USERID as input in the function Module and execute simply.

So can you please tell me the Way to handle it?

I will really appreciate your answer.

Thanks

Ali
