Unable to determinate case type: Usage of CL_SCMG_BUFFER_HELPER_CASEATTR->SELECT_AND_BUFFER

Hi,

I am trying to add a document to a case in FM. The problem is that he is not able to determine the case type. The case guid exists but the parameter table entries is empty when I call the method. Therefore the method is not able to determine the case type.

What is required to have "entries" filled?

Kind regards, Vanessa
