How To Fix E2259 - & is not classified - select an enhancement category (see documentation)

E2259 - Overview

• Message type: E = Error

• Message class: E2 - DE Data Dictionary

• Message number: 259

• Message text: & is not classified - select an enhancement category (see documentation)

What causes this issue?

The choice of an <DS:DE.DE_RADIO_EXCLASS>enhancement category</> is
necessary. The reason is that in programs where there is no active
Unicode flag, structure enhancements - in particular for type checks and
in connection with deep structures - can cause syntax and runtime
errors.
In programs where there is an active Unicode flag, statements, operand
checks, and accesses with offset and length are problematic if - for
example - numeric or deep components are inserted in a purely
character-type structure. In this way the structure loses its
character-type nature.

How to fix this error?

In the following dialog box, choose an enhancement category for the
structure:
<ZK>Cannot be enhanced</>
The table/structure must not be enhanced.
<ZK>Can be enhanced and character-type</>
All the structure components and their enhancements must be
character-type.
<ZK>Can be enhanced and character-type or numeric</>
The structure and its enhancement must not contain any deep data types.
<ZK>Can be enhanced in any way</>
The structure and its enhancement may contain components whose data type
can be of any type at all.

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

If you are uncertain here, read the section entitled
<DS:DE.DE_RADIO_EXCLASS>Enhancement Category</> .
