• Message class: 1Q - Messages In-House Banking

• Message number: 501

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

What causes this issue?

When creating a new route definition in bank area &V1&, at least one of
the fields <ZK>Route</> &V2&, <ZK>Bank country</> &V3&, or <ZK>Bank key
</> &V4& was not filled for the executing bank.

System Response

The Customizing entry was not created.

How to fix this error?

Cancel processing and create the entry again. Since the route defines
the next executing In-House Cash Center, none of the above fields may
remain blank.
The system checks if the clearing account for the bank area exists.
However, you can leave this field blank temporarily while you are
making your Customizing settings. The clearing account for the
executing bank is not checked, since a different bank area is
responsible for it. You must therefore ensure that this account is
valid in your organization.
