We are using a simple file-sender channel with content conversion (FCC, from a csv-file).
This is a small example input file:
As you can see, there is a field delimiter (^) and the field lengths vary, as expected using csv.
So any fixed-field-length stuff is off the table.
Therefore Recordset-Structure is defined as: DATA,*,FOOTER,1

seems to adress the problem, but whenever I leave out the keyFieldValue for the DATA-Lines, I can't even start the channel without getting an error.
com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.lang.Exception: java.lang.Exception: java.lang.Exception: Error(s) in XML conversion parameters found:
Mandatory parameter 'DATA.keyFieldValue': no value found
Problem being, that the content of the key field (DATA.field#1) does also vary (as all other fields will) and the FCC parameter [NODE].keyFieldValue does not seem to have any wildcard or regex-magic.
How can I force the FCC to collect all sets that start with a number, or even a digit, or do not start with an E, or whatever comes to mind.
