• What is the cause and solution for SAP error message WRF_CHAR_VAL036 - Characteristic type for &1 not changeable; is not "character format" ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_CHAR_VAL036
  
  Text: Characteristic type for &1 not changeable; is not "character format"
  
  Cause:
  This error occurs when you attempt to change the characteristic type of a characteristic in SAP that is not of the "character" format. In SAP, characteristics can have different data types (formats), such as:
  
  Character (CHAR)
  Numeric (NUM)
  Date (DATE)
  Time (TIME)
  etc.
  
  The system restricts changes to the characteristic type if the characteristic is not of the character format. This is because certain operations or changes are only valid for characteristics defined as character type.
  
  When does this happen?
  
  When trying to change the characteristic type (e.g., in classification or variant configuration).
  When trying to assign or modify values or properties that are only valid for character-type characteristics.
  Possibly during transport or customization activities where characteristic definitions are being adjusted.
  
  
  Solution:
  
  
  Check the characteristic format:
  
  Go to transaction CT04 (Change Characteristic).
  Enter the characteristic name &1 (the one mentioned in the error).
  Check the Data Type or Format of the characteristic.
  
  
  
  If the characteristic is not of type "character":
  
  You cannot change the characteristic type as requested.
  You need to either:
  
  Use a characteristic of type "character" if the operation requires it.
  Or adjust your process/requirement to work with the existing characteristic type.
  
  
  
  
  
  If you need a characteristic of character type:
  
  Create a new characteristic with the required character format.
  Migrate or adjust your data/process to use this new characteristic.
  
  
  
  Review the process or program logic:
  
  If this error occurs during a program run or customization, check the logic that attempts to change the characteristic type.
  Ensure it only tries to change characteristics of character format.
  
  
  
  
  Related Information:
  
  Characteristics in SAP are used in Classification (CL) and Variant Configuration (VC).
  The characteristic format is defined at creation and generally cannot be changed later.
  The error message is a safeguard to prevent inconsistent or invalid data definitions.
  For more details, you can check SAP Notes or documentation related to characteristics and classification.
