How to put files from Power Apps into Dataverse (Common Data Service)

Hello,

 

I am trying to put a file of any format from Power Apps into a file field in Dataverse (Common Data Service).

However, I can't get it to work due to a limitation on the Power Apps side, even if the file size is smaller than what I have set in Dataverse.
(Dataverse's file size limit setting is 128MB).

 

Do you have any ideas?

 

Thanks.

Hi @Sukiyaki_Osaka ,

 

I believe the issue is that the Dataverse Web Api request limit size is 16 MB, which requires files larger than 16 MB to be sent in chunks of 4 MB or less. The Attachment control in Canvas App is likely not implemented with this native support for the Dataverse File column to do this chunking.

 

Unfortunately this means that you'll only be able to send files 16 MB or smaller at this time using the control. The other option would be developing a PCF file upload control that can chunk the large files and send to Dataverse.

 

I have submitted an idea to enhance the Attachment control with native support for the Dataverse file type. If you would like to see this enhancement as well, I would appreciate your vote at the link below so that there is a higher chance of it being noticed and prioritized by the product team.

Hi @Sukiyaki_Osaka,

 

Could you provide some more details on the behavior you're experiencing? Are you using a Canvas App or Model-Driven App to add the file? Are you seeing any specific errors?

Have you confirmed the file type extension is not blocked in your environment (you can see this in System Settings)?

Hello @ChrisPiasecki ,

 

I am using the form function in a canvas application.

When I try to submit a file to Dataverse using the SubmitForm command, the output is "The maximum upload size supported by power apps for common data service is 16384KB".

 

The extension used in the file I executed is not blocked.

 

Therefore, I would like to know if there is a better way to register large size files from Power Apps to Dataverse.

 

Thanks.

Hi @ChrisPiasecki 

 

I was able to understand very well that the currently provided function does not allow sending files larger than 16MB.

 

However, this seems to be a factor that will hinder the development of useful applications. I will also vote for the idea you have given.

 

Thank you very much.

Hi @Sukiyaki_Osaka,

 

I agree it's quite inconvenient. That being said, I would caution against storing many large files in Dataverse as it can quickly eat up the file storage quota, and extra storage capacity add-on is quite expensive compared to other services such as SharePoint or Azure Blob Storage. Note that if uploading to SharePoint in the same manner you're attempting, you'll still run into the current 50 MB limit that the Attachment control in canvas app supports (apparantly 100 MB is planned but don't know when).

 

Model-Driven Apps have native SharePoint integration available that you may want to consider as well.
