Delimiter error while testing edi schema

I have created an EDI schema of v99A:DIRDEB through ‘Install doc type’ link in EDI admin page. But while trying to test a sample file to verify it, i am getting the following error.

" Could not run ‘TDIRDEB’.
java.lang.RuntimeException: [FFP.0003.0000] Delimiters not set"

can anyone help me out in this.
Thanks in advance

Did you check the EDIFFSchema of this EDIFACT document type whats delimiters its expecting or in your test flow convertToValues (specify delimiters per the test file)…

Where exactly its failing which step?? envelopeProcess or convertToValues??

Also do make sure your sample file is properly delimited…use some ultra-edit hex tool for diagnostics…
