VAT Entity to consider Voucher distribution level GL BU instead of BU level GL BU

Hi,

I have a question related to Vat setups in PeopleSoft payables. I will explain by taking an example:

Lets say, there are 2 VAT entities one is setup as Non-Recoverable and another as Recoverable. Both these VAT entities are tagged to different GL BU's, Non-recoverable against A10 GL BU and Recoverable under B10 GL BU.

Now I have raised voucher against A10 payables BU with B10 GL BU. Now when I check the VAT Summary page on the voucher, VAT entity is pointing to A10 (settings) and amount calculated under Non-Recoverable. This is because the A10 Payables BU was tagged against A10 GL BU. But my expectation is the VAT Entity should point to B10 GL BU setting because B10 is set at voucher level (when we talk about the payables hierarchy.. voucher is the bottom one).
