Request for Clarification – VAT Defaulting Logic for Category-Based PRs

As part of the category-based procurement design, we need to confirm and stabilize the logic for defaulting the correct VAT rate on each Purchase Requisition (PR) line in iProcurement.

Since these PRs are category-based (i.e., not linked to inventory items), the VAT calculation must rely on the Purchasing Category and associated EBTax setup.

To achieve this, we have implemented a personalization to default the product category at the PR line level as per Oracle Note Doc ID 1501592.1. However, the VAT rate is still not calculating correctly or consistently.

Current Behavior:

• It appears that someone has enabled a "Calculate VAT" LOV at the PR line level, which allows users to manually select a Tax Classification Code and then click Apply to get the correct VAT rate. (We have only One Tax Classification Code)
