What’s happening?

  1. When adding GST codes in the Purchase Order, the GST calculation is not occurring, and the use case is not reflected in the statistics.
  2. An error occurs when trying to create an invoice from a purchase order after changing the GST posting group from Foreign to a GST business, preventing the lines from being pulled through.

 

Reason:

  1. This with GST calculation appears to be related to specific GST codes, as GST is calculated correctly when using other service codes.
  2. The inability to create an invoice for a receipt line after changing the GST posting group is due to the system recording the GST posting details in the posted receipt, which prevents the invoice creation when using a different GST posting group.

 

Resolution:

  1. For the GST calculation issue, it was identified that re-running the tax engine resolved the problem, allowing GST to be calculated as expected.
  2. For the GST posting issue, it is recommended to undo the receipt and correct the purchase order to re-post. If the GST posting group needs to be changed back to Foreign, the system will prevent this due to the recorded GST posting details. It may be necessary to involve developers to write tools to correct the values from code, but this should be fully tested in a non-production environment before applying any changes.
