how to include goods receipt in tax allocation process

Summary: For the Belgian government, the time of delivery is a taxable event not the processing of the invoice. So it is needed to report the goods receipt in the applicable tax boxes instead of the invoice. How can goods receipts be included in the tax box allocation process?

Content (please ensure you mask any confidential information): I have found the setup to have tax calculated on the goods receipt (https://docs.oracle.com/en/cloud/saas/supply-chain-and-manufacturing/26a/fapma/Chunk1032499018.html#s20046521). But when I check in table zx_lines, the receipts get a reportable_flag no. Only the purchase invoices are included in the tax allocation process, we also need the goods receipts in the tax reports.
