Difference and handling: MV_CARTEIR and MV_CXFIN

The MV_CXFIN parameter informs the specific bank account, and MV_CARTEIR informs the bank code. The banks entered in the previous parameters are considered the company's internal banks and, consequently, cannot issue checks.
Therefore, if the MV_CTBAIXA is set to C - Check and a Regular post is performed with an internal bank, the SE5 transfer will not be booked because, for this type of bank, no check transfer exists.
