• Message number: 500

• Message text: Key field not filled in route determination &2 in bank area &1

What causes this issue?

In the new route determination entry &V2& you have created in bank area
&V1& at least one of the key fields <ZK>Bank country</> &V3& or
<ZK>Bank key</> &V4& was not filled, or the fields <ZK>Transaction
currency</> or <ZK>Payment method</> have been left blank.

System Response

The Customizing entry was not created.

How to fix this error?

Change the new entry, making sure you fill all the key fields. You can
only leave the fields <ZK>Transaction currency</> and <ZK>Payment
method</> blank as generic entries. Since the above fields are key
fields for route determination, they cannot be changed once the new
entry has been created.
The <ZK>Route</> field must be filled, otherwise the route definition
is incomplete. However, you can leave this field blank temporarily if
the route has not yet been defined. You can add or change the <ZK>Route
</> field at any point later on. In this way, you can enter changes in
the payment methods between the IHC Centers. To ensure that the routes
are organized consistently, use the check reports delivered with the
system.
