fc.invoke error

[michaeljt]

Hello,

Following your example from wiki I am getting some errors after fc.invoke. Could you please let me know what might be causing these errors and if there is any way to correct them?

Thank you for your help

Sorry for the late reply. I have just tried to replicate your issue (but with table T000 because I don't have access to an ECC machine). For me it ran fine. Can you please confirm: Do you have a trace file from the RFC dll? Do you see any corresponding logs in SM21?

[mydoghasworms]

Perhaps it will help if you paste your code somewhere including everything from the start (minus your system details and login credentials, of course).

Oh yes, in your connection parameters add this: "trace" => 1, and examine the resulting trace file.

From the trace it looks like permissions problem:
