Hi Samantha73,

You can address this using an event subscriber to overwrite the custom name.

Subscribing to the following objects will give you the result you need:

Codeunit → Document-Mailing → OnBeforeGetAttachmentFileName

Table → Document Attachment → OnBeforeSaveAttachment

If you find this useful, feel free to mark this answer as suggested!

I've also created a GitHub repo with the code for you to check out.

With some tweak you can but the major question lies, how many downloads you are doing a day. If it's handful then why not to download and then rename. I had a similar question from one of our client and then the same approach we took, if the volume is higher then we have to get into the processing logic of the base.

In Business Central, when using Print Preview, the default PDF file name may not include the document number. To ensure meaningful filenames during PDF downloads, here are a few approaches you can consider:

1. Modify the Report Code to Include the Document Number

In AL, use the Report.SaveAs method.

Dynamically pass the document number as part of the file name when saving the report.

2. Use the File.View Method

Allows previewing a file before download.

You can adjust the logic so the downloaded file includes the document number in the name.

3. Customize the Report Layout

In Word or RDLC layouts, make sure the document number is visible in the header or footer.

This helps users identify and rename files more easily after download.

4. Use the OnCustomDocumentMergerEx Event (v21+)

Available in Business Central v21 or later.

Allows customization of the document merge and file naming before generation.
