I copied standard 'SDBIL_CI_STANDARD_CA' form and mentioned copied custom service in s4 output using brf+. Its working fine. If I tried to add/remove any parameter like text... in the custom form its ending with
"Error(s) occurred when rendering the output item."
"Messages have been generated during form rendering."
"Error when creating PDF for ZSDBIL_XYZ"
"Error@ADS: com.adobe.ProcessingException: com.adobe.ProcessingException: No output was generated while rendering: Stream for: PDFOut."
Thinking some mismatch in parameters commented all the subforms as well, but its still the same...any suggestions?
