Intercompany Receivables tax automatically copy on Payables invoice

I have two tax regimes: PL_VAT and DE_VAT, and two business units: HEI PL BU and HEI DE BU. Both tax regimes are currently subscribed to both business units. When I create intercompany transactions between these legal entities, if the AR provider is HEI PL BU, the Poland Inter EU 0% tax rate calculates correctly on the AR side. However, on the AP side, since both regimes are subscribed to both business units, both the German reverse charge tax and the Poland Inter EU 0% tax are being applied.

To resolve this, I created separate tax regimes specifically for intercompany transactions: PL VAT IC and DE VAT IC. The HEI PL BU is subscribed to the PL VAT IC regime, and the HEI DE BU is subscribed to the DE VAT IC regime. This configuration correctly applies the relevant taxes. However, with this approach, I am unable to locate these transactions in the JPK report.
