Converting bank account number when updating Isah version 4.5.4 to 4.5.5

When you update your Isah version 4.5.4 to version 4.5.5, the value in the Bank account field is converted automatically (Suppliers module, Suppliers form; Customers module, Customers form; and Personnel module, Employees form). Depending on the value in the Bank account field in Isah 4.5.4, the Bank account and/or IBAN fields are populated in the corresponding forms in Isah 4.5.5.

If, in Isah 4.5.4, the Bank account field contains an IBAN, the IBAN is converted and copied to both the IBAN field and the Bank account field in Isah 4.5.5. An IBAN has an initial string consisting of two letters followed by two digits. If the initial letters of the IBAN are 'NL' and the country code in the Isah database is also 'NL', the Bank account field is populated with the original Dutch bank account number. The bank account number is derived from the IBAN.
