Hi Team,

Greetings!

We have the custom extract with input parameter as effective date (mandatory one) .

We have the attribute in the employee record in main data group with Effective_date which gets the value from input date

This was working good earlier and the input effective date was getting used and was showing up in the XML as well (output).

But, this has suddenly stopped working where the effective date field is not showing up in the XML and the fields dependent on the effective date are going blank in the output, and there has been no change to extract or flow pattern.
