W8174
- Constants are restricted to only 80 characters ?SAP Error Message:
W8174 - Constants are restricted to only 80 characters
Cause:
This warning occurs when you try to define a constant in ABAP whose value exceeds the maximum allowed length of 80 characters. In ABAP, constants are defined with a fixed value, and the system restricts the length of this value to 80 characters.
For example, if you write:
CONSTANTS c_long_constant TYPE string VALUE 'A very long string that exceeds 80 characters...'.
and the string literal exceeds 80 characters, the system will issue this warning.
Explanation:
Shorten the constant value:
Reduce the length of the constant value to 80 characters or less.
Use variables instead of constants:
If you need to store a string longer than 80 characters, consider using a variable instead of a constant.
Split the constant into multiple parts:
If the long string is necessary, split it into multiple constants each with less than 80 characters, and concatenate them at runtime.
Example:
CONSTANTS c_part1 TYPE string VALUE 'First part of the long string...'.
CONSTANTS c_part2 TYPE string VALUE 'Second part of the long string...'.
DATA long_string TYPE string.
long_string = c_part1 && c_part2.
Use text symbols or external text files:
For very long texts, consider storing the text in text symbols or external files and read them at runtime.
string
type can hold very long strings, but constants are limited in their literal length.If you provide the exact code snippet causing the warning, I can help you refactor it accordingly.
