I am trying to write the log files for Insert and Update records into a single file.
Can this is done in Informatica Cloud tasks.
I don’t think such out-of-the box feature exist in Informatica Cloud. You many need to handle this requirement with scripting using Pre or Post command line process.
This would be a good one to post on the Ideas site: https://community.informatica.com/community/products/informatica_cloud?view=idea
I'm interested in learning more about the use case you have in mind.
