Hi,

 

Approval amount is not showing up as the sum of tax and requisition amount. It just shows up as the requisition amount

Is this a tax setup or something controlled in SSP?

Currently this is what is shown

Recoverable Tax    -    1.00 AUD
Nonrecoverable Tax    - 0.00    AUD
Requisition Amount    - 10.00    AUD
Approval Amount    - 10.00        AUD

Thanks

Alex
