“Error generating the test frame” In SE37

Normally when we are executing some function modules (through SE37) we will get some kind of error like “Error generating the test frame”.

Solution:
This error will come when we have complex parameters in the Function modules.
Test environment of function builder can’t represent these parameters in the import tab (in input) For example : generic data types, Strings, xstrings, Object references.
