• What is the cause and solution for SAP error message DDLS260 - Nested SEARCHED CASE does not return any consistent data type info ?

  The SAP error message DDLS260 indicates that there is an issue with a nested SEARCHED CASE statement in your ABAP code. This error typically arises when the different branches of the SEARCHED CASE statement return inconsistent data types, which can lead to ambiguity in the expected output type.
  Cause:
  The primary cause of this error is that the SEARCHED CASE statement has multiple branches that return different data types. For example, if one branch returns a string and another returns an integer, the ABAP compiler cannot determine a consistent return type for the entire SEARCHED CASE statement.
  Solution:
  To resolve this error, you should ensure that all branches of the SEARCHED CASE statement return the same data type. Here are some steps you can take:
  
  
  Check Data Types: Review each branch of your SEARCHED CASE statement and ensure that they all return the same data type. If they do not, you may need to convert them to a common type.
  
  
  Use Type Casting: If necessary, use type casting to convert the values to a consistent type. For example, if you have a branch returning an integer and another returning a string, you might convert the integer to a string.
  
  
  Refactor Code: If the logic allows, consider refactoring your code to avoid using a nested SEARCHED CASE statement or to simplify the logic.
  
  
  Example:
  Here’s a simple example of a SEARCHED CASE statement that could cause this error:
  DATA(result) = ''.
  
  CASE some_variable.
    WHEN 'A'.
      result = 'String A'.  " String type
    WHEN 'B'.
      result = 100.         " Integer type
    WHEN OTHERS.
      result = 'Default'.   " String type
  ENDCASE.
  In this case, result is assigned a string in the first and last branches, but an integer in the second branch. To fix this, you could convert the integer to a string:
  DATA(result) = ''.
  
  CASE some_variable.
    WHEN 'A'.
      result = 'String A'.
    WHEN 'B'.
      result = CONDENSE( 100 ).  " Convert integer to string
    WHEN OTHERS.
      result = 'Default'.
  ENDCASE.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP ABAP documentation for more details on the CASE statement and data types.
  Debugging: Use the ABAP debugger to step through your code and inspect the values being assigned in each branch of the SEARCHED CASE.
  Code Review: If you are working in a team, consider having a peer review your code to catch any inconsistencies in data types.
  
  By ensuring that all branches of your SEARCHED CASE statement return a consistent data type, you should be able to resolve the DDLS260 error.
