FX-SCH-A-001019: A line attachment needs a file-type attribute

In short

Error: fails the selected checks.

FX-SCH-A-001019 means an embedded attachment in your line's additional document reference is missing the mimeCode attribute. Add it to ram:AttachmentBinaryObject with an allowed MIME type that matches the file.

On this page

What it means

This rule checks whether mimeCode exists on ram:AttachmentBinaryObject inside a line's ram:SpecifiedLineTradeAgreement/ram:AdditionalReferencedDocument. An empty attribute satisfies this presence check. The test does not inspect the MIME value or the attachment's contents.

Why it matters

The mimeCode attribute declares the embedded attachment's file type.

How to fix it

Check the attachment's actual format. Add its corresponding allowed MIME type to mimeCode, such as application/pdf for a PDF. If your software omits the attribute, have its export corrected. Export and recheck.
