Anybody know what that error message means?

Hello,

Please provide some context to your question.

1- What version and patch(this needs to be the least provided)
2- Is your subprogram has a GRP variable as a parameter?
3- Are you sending that in your request?

You could look at some existing examples on other subprograms to see how they are done.

I am using Version 11 patch 4. 

There is no GRP variable in my subprogram. 

I am not sending a GRP in my request. The GRP is coming from the group in the mapping of a webservice. 

I was following a solution on RKL solutions and I am getting this error message when I try to test it using CAdxWebServiceXmlCC soap web service. 

Any ideas what could be causing this?

I did exactly what she did in this article and I am getting that GRP error.

Do you have other examples of using a subprogram?
