Hi @Heena_9980400 ,
If the tables are the same (which they should be since these should be copies of each other...) then this is quite simple. I first do a "save as" and name the non-prod ones with the source on them (itg, dev ) and so the production one has the real name without that designation.
Then, go into the file, options, data source settings and select the data source you want to change. Select change datasource button and then put in the new path.
Save the change, select apply changes , refresh if you want and then publish.
Did I answer your question? Mark my post as a solution!
