Summary :
When invoking function modules containing complex IMPORT, EXPORT, or CHANGING parameters in SAP, the ABAP runtime error PARAMETER_CONVERSION_ERROR may occur due to XML data conversions. Issues arise primarily when there's an abnormal termination of the RFC server session or mismatches between actual parameters and those expected by the function module. This can be diagnosed by reviewing the system logs via SM21 or following guidance in SAP Note 532918 to resolve discrepancies and prevent the CALL_FUNCTION_SEND_ERROR.
