How do you initially upload the XSLT file to a Document Transformation integration system?

To upload an XSLT file to a Document Transformation integration system, you use the Configure Integration Attachment Service.

As per Workday documentation:

“The Configure Integration Attachment Service option on the Related Actions menu allows you to attach and manage XSLT files or other transformation documents used in Document Transformation integrations.”

This is the initial and correct method to upload the XSLT used for transforming incoming or outgoing XML.

Why the others are incorrect:

B. Configure Integration Attributes configures integration behavior, not attachments.

C and D reference invalid or misnamed tasks; they are not valid Workday tasks for XSLT upload.
