Posted on by joelhtown80 30

Hi All,

I am creating an invoice and attaching its PDF file using Power Automate. But I am getting an error in D365-->F&O when trying to attach a second PDF file. Kindly help.

The scenario is this:

1. Create an invoice in D365->Finance and Operations via Power Automate.

2. Attaching the PDF file (Test.pdf) to the invoice via Power Automate (using a data package).  

3. Invoice is created successfully in F&O. PDF file is attached successfully to the invoice. 

4. Attach another PDF file (Test2.pdf) to the invoice. ***Note***: I used the same Test.pdf file and just renamed it to Test2.pdf. Power Automate ran successfully but the file Test2.pdf was not attached to the invoice. The job execution prompts the error below

    Data entity is using invoice number document as primary key.

    Data entity supports a single attachment. When you attach a second document you are not inserting a new attachment  but updating the existing one. Updating that is not supported in data entity.

    You need to extend data entity to support that

    Hi nunomaia,

    I'm new to this but can you guide me on how to extend the data entity?

    Hi,

    The field FileContents and FileName are both computed columns. This means that they cannot be directly used for insert/update events without additional post-event logic (Computed columns and virtual fields in data entities - Finance & Operations | Dynamics 365 | Microsoft Learn).
     
    See standard insertEntityDataSource method on DocuRefEntity for reference on how inserts are managed:
     
    So, for updates you would need to implement post-event logic to the updateEntityDataSource method in the same manner. Since this is not available in standard, it could be a process that should not be performed. You would need to investigate how updates to attached files are done in other scenarios.
