Distinct filter from sharepoint list

Hi

Im trying to filter value to be displayed in a dropdown box.

I want to filter from a SharePoint list and this works fine.

 

Distinct(Filter(AssetListData;Title=ItemData.SelectedText.Value);Vendor)

Example above i filter from list displays Vendors based on Title

Now i want to Filter Model based on Vendor and Title.

 

Currently my filter for the Model field looks like this.

Distinct(Filter(AssetListData;Vendor=VendorData.SelectedText.Value);Model)

With the above i will get all results that matches the Vendor but i want it to distinct not only vendor but also Title.

 

If the a Vendor for example Microsoft has 500 models then all is showend. But i want to filter like this.

If Title is = TV and Vendor is Microsoft show only models that are TV and Vendor Microsoft.

Filter(DataSource,Title=ItemData.SelectedText.Value && Vendor=VendorData.SelectedText.Value)

The above seems to work without any delegation warnings.

Re: Distinct filter from sharepoint list

Hi @JimmyWork 

As you are aware, Distinct() can only create a single column table.  However, you can use the GroupBy() function to accomplish your goal. see https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-groupby  This function can use multiple columns to group the data and you can then filter it on those columns.  You can reshape the data in the other columns by using the shaping functions to only show the other columns that you are interested in.  see https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-table-shaping.  Be aware that these functions are not delegatable in SharePoint so if you have a large list, the resulting tables may not be complete.

@Drrickryp Thank you

 

Im trying to create a cascading dropdown using the filter. How can we work around the delegate for large list?
