The type taxes is not pulling correctly in the Nota Fiscal (TX Code: J1B3N) - URGENT

[Mari-1605]

Hello Everyone,

MIRO bookkeeping in SAP ECC for service Nota Fiscal (invoices) that have tax withheld in order to comply with Brazil's new REINF tax obligation is pulling the wrong tax type.
Below is an example of a service Nota Fiscal (invoice) that is booked with PCC withheld on the Nota Fiscal item:
In the Taxes tab, the code IGEQ (PCC withholding 4.65%) is pulling incorrectly in the Service Nota Fiscal item.
The correct one  is the Service Nota Fiscal pull automatically the IIRQ tax type in the MIRO and Service Nota Fiscal (J1B3N):

TX Code: J1B3N

Tx Code: MIRO

This Service Monitor screen shows the capture of service note information, but for MIRO bookkeeping, a link is made to the service monitor, which calls MIRO and does the automatic bookkeeping.

Tax Code: /N/TCSR/MONITOR

The configuration of withholding taxes for the posting of service invoices is done in the supplier's master data:

TX Code: XK03

The screen below shows the taxes types that are registered in TX CodeJ1BTAX:

See below that the settings for this withholding tax (PCC) are correct to consider the withholding on the payment installment and not on the Nota Fiscal posting. See below:

OBS: Before the service monitor was implemented, the MIRO was already booked in this way with this IGEQ code in the invoice item, incorrectly.

Cold you please help me to explain the best way to solve this issue?

Thanks so much
