How To Fix CY417 - A sort key must be entered for the group 0

CY417 - Overview

• Message type: E = Error

• Message class: CY - Capacity Requirements Planning

• Message number: 417

• Message text: A sort key must be entered for the group 0

What causes this issue?

When defining the sort you entered a group 0 and either no sort key or
an extra sort layout key. However for the group 0, only the entry of
one sort key is intended.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Such an entry has the effect that the objects of all the requirements
groups of a chart are sorted using this sort key.
If, for example planned or work orders are displayed and if you are
using a sort key that contains the planned order or production order
number then all the objects are sorted according to the order number
independently of whether it involves a planned order or a work order.

How to fix this error?

You should enter a sort key for the group 0. Then you cannot enter
other groups.
