Hi all, I just uploaded a new dataset to an existing analysis, and I am unable to get one of my fields to map. All fields except for the “Project type” field are correctly mapped and are filtering just fine. I originally made the mistake of titling the column “Project Type” (capitalizing the word ‘type’), so Quicksight was unable to map the field correctly. I then tried creating a calculated field called “Project type” (the word ‘type’ correctly not capitalized), but the mapping did not update. I then created a new, identical column in my new dataset with the correct title and it still is not mapping. What can I do to make this work? ---

hi @prestonb Welcome to Quick Sight Community and thank you for posting a question. I am guessing you are trying to have cross dataset filtering. Cross dataset filtering should work even if all the fields in target dataset don’t have a match. What matters is whether the fields being used for filtering are present in target dataset and correctly picked as a match in the field mapping. Are you trying to create a filter on Project type column? kind regards, Wakana ---

Hi Wakana, that is correct: I’m trying to create a cross-dataset filter on the Project type column. You mentioned that it’s important to correctly pick the field as a match in the field mapping – can I do that myself? I’m only aware of the automatic mapping, which hasn’t been working. ---

Hi @prestonb, It’s been awhile since there’s been any activity on this topic; were you able to find a work around solution for your case or are you still in need of further assistance? Here’s some additional documentation about [mapping and joining fields](https://docs.aws.amazon.com/quicksight/latest/user/mapping-and-joining-fields.html). Let us know if you have any additional questions; if we do not hear back within 3 business days, I’ll go ahead and close out this topic! ---
