What causes this issue?

The expression &v1& delivers a value which is longer than 5000 bytes.
The binding only supports fields with a length of up to 5000 bytes. But
the value has a length of &v2& bytes.

• What is the cause and solution for SAP error message W8066 - Value for expression &1 cut ?

  SAP Error Message:
  
  W8066 - Value for expression &1 cut
  
  Cause:
  This warning message occurs when the value assigned to a particular expression (variable, field, or parameter) is too long and gets truncated (cut) to fit the defined length of the target field or variable. Essentially, the system tries to assign a value that exceeds the length of the receiving field, so it cuts off the excess characters.
  
  Explanation:
  
  The placeholder &1 in the message is replaced by the name of the expression (field or variable) whose value was cut.
  This is a warning (not an error), so the program continues to run, but the data assigned is incomplete.
  It typically happens during assignments, moves, or when passing parameters where the source string is longer than the target field length.
  
  
  Solution:
  
  
  Check the length of the target field:
  
  Verify the data element or variable length of the target expression.
  If the length is too short to hold the expected data, consider increasing its length.
  
  
  
  Check the source data:
  
  Ensure that the source value is not unexpectedly long.
  If the source data is longer than expected, investigate why and whether it should be truncated or handled differently.
  
  
  
  Modify the program logic:
  
  If truncation is acceptable, you can explicitly truncate the source value before assignment using string functions like CONDENSE, OFFSET, or substring operations.
  If truncation is not acceptable, adjust the target field length or redesign the data flow.
  
  
  
  Suppress the warning (if intentional):
  
  If truncation is expected and harmless, you can suppress the warning by handling it in the program or adjusting message control.
  
  
  
  
  Related Information:
  
  This message is a warning (W), not an error, so it does not stop program execution.
  Common in ABAP programs during MOVE, MOVE-CORRESPONDING, or parameter passing.
  Check the data dictionary (SE11) for the data element or structure field length.
  Use debugging or logging to identify where the truncation happens.
  Similar messages: W8065 (Value for expression &1 too long), which also relates to length issues.
  
  
  Example:
  DATA: lv_short TYPE c LENGTH 5,
        lv_long  TYPE c LENGTH 10 VALUE 'ABCDEFGHIJ'.
  
  lv_short = lv_long. " Warning W8066: Value for expression lv_short cut
  In this example, lv_long has 10 characters, but lv_short can only hold 5, so the value is truncated and the warning is issued.
