BS invoke problem during WF simulation
I would like to simulate a workflow which calls a BS but when it gets there I get the following error message:
"Error invoking service 'VFH Utilities', method 'WriteErrLog' at step 'Write Error Log 2'.(SBL-BPR-00162)
--
The method 'WriteErrLog' is not supported on Business Service 'VFH Utilities'.(SBL-DAT-00323)"
Since it is working on the environments where it is deployed I know it is fine, it can be a setting problem in Tools but what? The BS is custom but it is very old it surely has been compiled to the actual srf and it wasn't modified nowadays.
Please give me some advice!
