Error: Document date 00/00/0000 is incorrect in item 0000000001 in PRRW check

Hi Experts,

I am running PRRW for a trip that consists of both expense an mileage, on checking the document I get the following error:

Document date 00/00/0000 is incorrect in item 0000000001, on debugging it was found that for the mileage document date is not getting populated somehow.

Below is the screenshot of the variant I am using to create the document in PRFI:

Please let me know, what am I missing.
