How To Fix TR166 - Key description contains old default

SAP Error Message - Details

• Message type: E = Error

• Message class: TR - Change and Transport System

• Message number: 166

• Message text: Key description contains old default

What causes this issue?

A key definition was processed that was defined according to an
outdated description rule. An area was defined by specifying a FROM
field and a TO field.
The old specifications were:
Object : "&V1&"
Table : "&V2&"
FROM field : "&V3&"
TO field : "&V4&"
Specifying intervals with upper and lower limits to define key
ranges can have undesired effects and/or cause errors, as the decision
as to whether a given key lies in the interval depends on the codepage
used.

System Response

You must enter a new definition to replace the old one.

How to fix this error?

List generic areas to define key ranges.
Delete the entry and add the appropriate generic description lines.
Example: old: from Y to ZZZ
should be replaced by
new: Y*
and Z*
Therefore, in this example, the one old line is replaced by two new
ones.
<ZH>Example of error case:</>
Range: XX* to YY*
Permissible on ASCII computers: e.g. keys "Z1234", "Z9*"
Permissible on EDCDIC computers: e.g. keys "Y1234", "Y9*"
The permissible ranges on the two types of computers are mutually
exclusive; when such a key is actually permitted, this is due to
coincidence more than anything else.
In contrast, configured key specifications, such as
A* to X* ,
are not critical, as no special characters and/or numeric values
could be involved in a codepage.
