How To Fix SABP_RUNT001 - Maximum string length (&1 bytes) exceeded

SABP_RUNT001 - Overview

• Message type: E = Error

• Message class: SABP_RUNT - Message Class for ABAP Runtime

• Message number: 001

• Message text: Maximum string length (&1 bytes) exceeded

What causes this issue?

The current statement attempted to modify an ABAP string in such a way
that the maximum string length of &V1& is exceeded.
This situation can occur in all statements that make strings longer
(such as CONCATENATE, REPLACE, or SHIFT LEFT), plus in string ex
pressions and in CALL TRANSFORMATION.

How to fix this error?

Once the exception CX_SY_STRING_SIZE_TOO_LARGE is caught, the content of
the target string is undefined. The target string may already be
modified in parts and have reached this size. For this reason it should
be initialized once the exception is caught.

• What is the cause and solution for SAP error message SABP_RUNT001 - Maximum string length (&1 bytes) exceeded ?

  The SAP error message SABP_RUNT001: Maximum string length (&1 bytes) exceeded typically occurs when a string variable in an ABAP program exceeds the maximum allowable length defined by the system. This can happen in various scenarios, such as when processing large amounts of data, handling long text fields, or when concatenating strings.
  
  Cause:
  
  Data Length Exceeded: The string being processed exceeds the maximum length defined for that data type. In ABAP, the maximum length for a string is typically 255 bytes for character strings and can be larger for other types, but specific contexts may impose stricter limits.
  Concatenation Issues: If you are concatenating multiple strings, the resulting string may exceed the maximum length.
  Data Type Mismatch: Using a data type that cannot accommodate the length of the data being processed.
  
  
  Solution:
  
  Check Data Length: Review the data being processed to ensure that it does not exceed the maximum length. You can use the strlen() function
