It is possible to enter negative amount at the ISP AP invoice line level(supplier submitted invoice

Summary:

Dear Team,

The supplier has submitted an AP invoice through the Supplier Portal.

That invoice pertains to insurance. As per my client's requirement, multi-period accounting must be applied to this invoice

According to Oracle's standard features, the multi-period accounting solution does not apply to Purchase order -matched AP invoices.

So we provided below workaround to create Multi-period AP invoice which is linked with Purchase order

As a workaround, we are adding a new AP invoice line with a negative amount and PO charge account updated at ap invoice line distribution level.

Additionally, we are creating another AP invoice line with a positive amount and updating the multi-period start date, end date, and accrual account accordingly.
