Thanks Ravi for your suggestions.
Below expression works for me.
LDVERIFIED=[ORIGINAL].LDVERIFIED
In addition to this I have another requirement. if the above validation result is TRUE, then field name (LDVERIFIED) need to be syndicate in the file (outbound port). Pls note - only changed field name is required ( value is not required)
There are totally 25 fields with above conditions.
Please suggest
