Pay group parameter in expense report exports

Hi all,

We have set up a separate pay group for our expense reports (EXPENSE) which differs from our default pay group (STANDARD).

During the export process, the parameter for "group" is populated with the EXPENSE pay group, but upon reviewing the batch in Payables, the STANDARD group is displayed. My understanding is that the parameter used during this process should override any settings at the Payables or Supplier level, but it isn't. What am I missing?

Thanks!

Vanessa
