DSXchange

I got below fatal error when running my duplicate matching.

Unduplicate_Match_177: Unable to locate column keyChange in the input link with the following schema:
record
( qsMatchDataID: uint64;
C_HOUSE_NUMBER: nullable ustring;
)


My souce data just have 3 columns
Source varchar not nullable
Row BigInt
C_HOUSE_NUMBER varchar not nullable

Link ordering in Unduplicate_Match is correctly define.

Please advice what may causing the error?

Thanks in advance

Is it possible that you have a Special Variable handling (like a NOFREQ) for a column called KeyChange?

Did you change the Match Specification and then forget to 'Provision All'?

If you are using 8.7, you can run the Match Specification Report and see if that column appears on the report.
