Hi @Raffy Comendador ,
Thanks for your query and using Microsoft Q&A forum.
Have you tried enabling the first row as header
property in your source dataset? If not could you please try it and see if that helps.
In case if that is not helpful, the alternate would be to go with parameterized mapping for each source file. To explore more about dynamic column mapping please refer to this video - Dynamic Column mapping in Copy Activity in Azure Data Factory
Here is the public doc related to parameterized mapping: Parameterize mapping
Hope this info helps. Do let us know if you have further query.
