pi 7.3 JAVA Single Stack IDOC_AAE metadata issue

Hi ,

We are currently on pi7.3 single stack ,

We have extended CREMAS with few Zsegments before it was working fine. Recently we have added one more Zsegment from then it started again with an error as below.

IDoc: Error before sending : IDocException com.sap.conn.idoc.IDocParseException: (7) IDOC_ERROR_PARSE_FAILURE: An IDocIllegalTypeException occurred while parsing IDocXML for type <CREMASEXT>:

state=READING_FIELD_STARTTAG, charPosition=1460, lineNumber=1, columnNumber=1461

This columnnumber is nothing but the newly added Zsegment .. so now the problem is its not updated with Metadata currently in PI system. But in PI 7.3 single stack we don't have provision to update Metadata manually .
