IDOCXmlToFlatConvertor + Z IDOC Extension

Hi Experts,

We are getting the following error message while trying to use the IDOCXmlToFlatConvertor standard module with Z IDOC extension. The IDOC standard works perfectly.

The our scenario is IDOC >>SAP PI 7.11 (IDOCXmlToFlatConvertor) >> SFTP

Basic type: ACCONF01

Extension: ZP10FINACCONF01_EXT

--Error message---

Message processing failed. Cause: com.sap.conn.idoc.IDocParseException: (7) IDOC_ERROR_PARSE_FAILURE: An IDocConversionException occurred while parsing IDocXML for type <ZP10FINACCONF01_EXT>: state=READING_FIELD_VALUE_TAG, charPosition=926, lineNumber=2, columnNumber=888

Once the Z1P1DCIW_BLOCKDATA segment is removed from the XML, it works fine (using the RWB to send it)

We alredy tried to delete & remove the metadata from IDX2, update the cache.

Is there any place to set up the Z extension in the configuration steps?

Thanks in advance,

Leandro Silva
