Hi everyone
What I already do is calling a webservice (SAP BAPI) with LabVIEW in order to get some information from the ERP. To do this, a DLL call is required and it always works fine.
Now I'm looking for a LabWindows/CVI solution for this, so I built a shared library out of the LabVIEW-VI which contains the BAPI call. Now I have a DLL which calls a DLL, and obviously it doesn't work this way. No meaningful data is returned from the built LabVIEW-DLL, so I must assume that entire VI is not called properly. Even when I wire a constant value to the output "daten" for debugging purpose I won't receive it as long as the subVI containing the DLL call is enabled within the LabVIEW-DLL. As soon as I disable the subVI is disabled the returned data is ok.
When I call the DLL with LabVIEW instead of CVI everything works fine.
Anyone faced this problem too?? After a long web research I have no idea what to do...
Many thanks for your help!
