Contraint on BVR adherent number / CPP pair
Contraint on BVR adherent number / CPP pair

First of all there is a confusion for the BVR coding line:
0100000600007>103559000000000020170013270+ 100007254>
              ^ reference beginning with   ^ adherent number
                bank client account number
                ( 6 chars )
You are naming the 6 chars client account number as BVR adherent number which is false.
Here Raiffeisen documentation : https://www.raiffeisen.ch/content/dam/www/rch/pdf/firmenkunden/zahlungsverkehr-und-konten/fr/fiche-produit-bulletin-versement-orange.pdf
However, both of these numbers can be used many times but the pair (adherent number / client account number) must be unique.
