Hello,

We have a requirement to default tax code on requisition line based on the purchasing category. Followed the steps in the document: https://docs.oracle.com/en/cloud/saas/procurement/22a/oapro/how-is-tax-coming-on-purchase-order-based-on-purchasing-category.html#u30011414 . However, it only works for PO and not the requisition. The customer does not have any item-based requisitions thus we have to default the tax code through Purchasing Category. Is there any way to achieve this?

Regards,

Selcuk
