Tax amount information not included in cXML PO

Summary:

We want to communicate the tax amount to suppliers via b2b communication for Purchase orders. The default cXML template is not populating the tax amount.

Content (please ensure you mask any confidential information):

The PO created gets communicated to the supplier through cXML. The PO has tax amount which helps supplier to populate the tax amount when Invoice is sent back to us. So we did some testing and found that the cXML communicated does not have tax amount on it. The original message created in B2B collaboration has tax amount but when it is transformed to supplier does not include it. Now we are struggling to add tag of tax amount.
