SAP Error Message - Details

• Message type: E = Error

• Message class: SFB - Messages for Formula Builder

• Message number: 516

• Message text: Concatenation not possible: Insufficient space

What causes this issue?

You have attempted to link up a line with the following line through
concatenation. The line that would then exist would, however, be too
long for the Formula Builder (max. 72 columns).

System Response

The operation was terminated.

• What is the cause and solution for SAP error message SFB516 - Concatenation not possible: Insufficient space ?

  The SAP error message SFB516, which states "Concatenation not possible: Insufficient space," typically occurs when there is an attempt to concatenate strings or data elements in a way that exceeds the allocated memory or buffer size. This can happen in various contexts, such as when working with internal tables, strings, or data structures in ABAP programs.
  Causes:
  
  Buffer Size Limitations: The target variable or data structure does not have enough space to hold the concatenated result.
  Data Type Mismatch: The data types of the variables being concatenated may not be compatible, leading to issues when trying to combine them.
  Incorrect Length Definitions: The length of the target variable may not be defined correctly, leading to insufficient space for the concatenated result.
  Large Data Volume: Attempting to concatenate large strings or data sets that exceed the maximum allowable size for the target variable.
  
  Solutions:
  
  
  Increase Buffer Size: Ensure that the target variable or data structure has enough space allocated. You can do this by defining the variable with a larger length.
  DATA: lv_result TYPE string.
  If you are using a specific data type, ensure it can accommodate the expected size.
  
  
  Check Data Types: Verify that the data types of the variables being concatenated are compatible. If necessary, convert them to a common type before concatenation.
  
  
  Use String Functions: Instead of direct concatenation, consider using string functions that handle memory management more effectively, such as CONCATENATE with the INTO clause.
  CONCATENATE lv_string1 lv_string2 INTO lv_result.
  
  
  Split Large Data: If you are dealing with very large strings or data sets, consider splitting them into smaller parts and concatenating them in a loop or in smaller chunks.
  
  
  Debugging: Use debugging tools to check the lengths of the variables involved in the concatenation to identify where the issue arises.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP ABAP documentation for more details on string handling and memory management.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Performance Considerations: Be mindful of performance when concatenating large strings or data sets, as this can impact the efficiency of your program.
  
  By addressing the above points, you should be able to resolve the SFB516 error and successfully perform the concatenation operation in your SAP environment.
