• Message text: Fields &1 and &2 have different field types

What causes this issue?

You tried to assign infocube field &V2& to planning scenario field &V1&
.
Both fields have different field types. You can only assign fields with
identical field types (characteristic, key figure, time, unit,
currency) to one another.

How to fix this error?

Check your assignment and only assign fields with identical field types
to one another.

• What is the cause and solution for SAP error message WXP168 - Fields &1 and &2 have different field types ?

  SAP Error Message:
  
  WXP168: Fields &1 and &2 have different field types
  
  Cause:
  This warning message occurs when two fields involved in an operation (such as a comparison, assignment, or join) have different data types or incompatible field types. For example, one field might be of type CHAR and the other of type NUMC, or one might be a packed number (DEC) and the other a character string, etc.
  SAP expects fields used together in expressions or conditions to have compatible data types to avoid runtime errors or unexpected behavior.
  
  Typical Scenarios:
  
  Comparing two fields of different types in a WHERE clause or IF condition.
  Assigning one field to another where the data types differ.
  Using fields in a join condition in Open SQL where the types do not match.
  Passing parameters to function modules or methods where the expected and actual types differ.
  
  
  Solution:
  
  
  Check the Data Types:
  
  Identify the data types of the two fields mentioned in the message. You can do this by:
  
  Looking at the Data Dictionary (SE11) for the fields.
  Checking the variable declarations in the ABAP program.
  
  
  
  Make Data Types Compatible:  
  
  Use explicit type conversions or casting if necessary. For example, use CONV or MOVE with appropriate conversions.
  Convert numeric fields to character or vice versa using functions like CONV, STRING, or WRITE TO.
  Ensure that fields used in joins or comparisons have the same type and length.
  
  
  
  Adjust the Logic:
  
  If the fields are inherently different and cannot be converted meaningfully, reconsider the logic or the way the fields are used together.
  
  
  Example Fix:  
  DATA: lv_char TYPE char10,
        lv_num  TYPE numc10.
  
  lv_char = '0001234567'.
  lv_num = CONV numc10( lv_char ).  " Convert char to numc before comparison
  
  IF lv_num = '0001234567'.
    " Your logic here
  ENDIF.

  SAP Notes: Sometimes SAP Notes provide fixes or clarifications if this warning is related to a specific SAP component or version.
  ABAP Documentation: Refer to ABAP keyword documentation for CONV, MOVE, and data type compatibility.
  
  
  Summary:
  
  Cause: Fields &1 and &2 have incompatible data types.
  Solution: Ensure both fields have compatible types by checking their definitions and applying explicit conversions if necessary.
  Check: Data Dictionary, ABAP code, and conversion functions.
