How To Fix TR164 - Caution when entering 'from-to' range

TR164 - Overview

• Message type: E = Error

• Message class: TR - Change and Transport System

• Message number: 164

• Message text: Caution when entering 'from-to' range

Important for entry of 'from-to ranges': code-page-specific entries
Unintended faulty effects may be produced when you enter intervals with
upper and lower limits when defining key ranges.
The reason for this is that the decision as to whether a given key lies
within the interval is code-page-specific. The example given below is
intended to document this. We recommend that you make the key range
definition by listing generic areas as in this way such dangers can be
avoided.
Example:
Range: XX* to YY*
Allowed on ASCII machines: e.g. keys 'Z1234', 'Z9*'
Allowed on EBCDIC machines: e.g. keys 'Y1234', 'Y9*'
The different (and presumably undesired) value ranges on the two
different types of computer are mutually exclusive, meaning that the
allowability of a particular key becomes chance.
Single-character key entries, on the other hand, do not cause problems:
A* to X* ,
since in this case it is not possible for special characters and/or
numerical values to get mixed up in any code page.

• What is the cause and solution for SAP error message TR164 - Caution when entering 'from-to' range ?

  The SAP error message TR164, which states "Caution when entering 'from-to' range," typically occurs when there is an issue with the range of values specified in a selection screen, particularly in transaction codes that involve data selection or reporting.
  
  Cause:
  
  Invalid Range Specification: The error often arises when the 'from' value is greater than the 'to' value in a range selection. For example, if you are trying to select a range of dates or numbers, entering a start date that is later than the end date will trigger this warning.
  Data Type Mismatch: If the data types of the fields being compared are not compatible, it can also lead to this error.
  Logical Errors: Sometimes, the logical conditions set in the selection criteria may not make sense, leading to this caution message.
  
  
  Solution:
  
  Check Input Values: Review the values you have entered in the 'from' and 'to' fields. Ensure that the 'from' value is less than
