Change mapping in the session

Question

I have a Informatica session which is linked to a wrong mapping. How do i change the mapping from M1 to M2 in the same session S1 and Workflow W1 WITHOUT importing/exporting as XML and making the changes ???

Answer 1

XML import/export is the only "official" way to do this. If you don't want to do that, you will have to create a new session S2 and attach the mapping M2 to that session.

One possible extra option, with disclaimer: If you have access to Informatica's Oracle database (that holds the metadata), you could perhaps make this change directly there. But you would really have to know what you're doing, or else you are likely to mess things up pretty badly. This is certainly not the recommended way of making changes!
