Hi,
LCR magnétique would be payment method "2" in France best practice.
It is similar to RIBA in SAP and follows the BOE processing.
Means the payment file is generated in 2 steps :
1 - F110 : Generation of the BOE with SGL code W
2 - FBWE : Remittance of BOE, generation of the file for the bank (file format FR01 or FR02, to be selected in the last tab of FBWE).
