• Message number: 304

• Message text: Cannot copy & to & because & exists in CWType area

What causes this issue?

You chose <LS>automatic assignment of a customizing wage type</> and
then entered the two parameters to create several copies of a model
wage type. But one of the wage type names you have just generated
already exists in the <LS>CWType</> field shown on the
screen.

System Response

The entry that had an existing wage type name is not created, but all
the other new entries are displayed in the table.

How can this happen?

You entered the following:
Wage type begins at <LS>1000</>
Number of wage types <LS>4</>
Increase per step <LS>10</>
However, an entry already exists on the screen for the wage type you
want to copy as 1020. In this case, only three new entries are created
in the table on the screen. These are:
<LS>OWType</> <LS>CWType</>
XXXX 1000
XXXX 1010
XXXX 1030
