Changing the data destination in a dataflow

Hi,

in a dataflow I need to change the data destination (a warehouse) for debug purpose.

I've noticed that when I try to choice the existing data destination I need to select it again and a complete data mapping with the source columns is proposed. This behaviour is not more useful and it should be preferable to change the existing data destination with the existing data mapping and not accomplish the data mapping again.

Now, any suggests to me to solve a such issue, please?! Thanks

    Thanks for using Microsoft Fabric Community.

    Apologies for the delay in response.

    Thank you frithjof_v for sharing the details,

    In addition, When you change the data destination in a dataflow, Fabric does automatically suggest a mapping of columns based on the source and destination schema. This auto-mapping feature can save a lot of time and effort. In most cases, the suggested mapping is accurate, and you only need to review and adjust it as needed. You don't need to manually map every single column, which would indeed be tedious.

    So, in your case, when you change the data destination for debug purposes, you can simply review the suggested column mapping and make any necessary adjustments. This should be a relatively quick and straightforward process.

     

    While the automatic suggestions can save time, it's important to consider the two limitations:

    Verification Needed: Even though Dataflow suggests mappings, it's crucial to review them before finalizing. The suggestions might not always be perfect, especially for complex data structures or when column names don't match exactly between source and destination.

    Incomplete Mapping: Automatic suggestions might not map all columns from the source. You might need to manually map additional columns if they're relevant for your debugging purpose.

     

    I hope this information helps.

     

    Thank you.

    Isn't the data mapping automatically suggesting mapping of columns? 

     

    I don't think you need to map every single column manually. I think it is auto-filled suggestions.

        Hi, the real issue is that respect to the existing data destination in a data flow, previously choosed, I shouldn't select a data destination again. The data flow should maintain the existing data destination without requiring a new selection.

        Thanks
