• What is the cause and solution for SAP error message CM_EHFND_FW_CALC_ENG135 - Usage of "&1" as both, fixed value and date, is not permitted ?

  The SAP error message CM_EHFND_FW_CALC_ENG135 indicates that there is a conflict in the usage of a variable or field in a calculation context. Specifically, it states that the variable "&1" is being used both as a fixed value and as a date, which is not allowed.
  Cause:
  This error typically arises in scenarios where:
  
  A variable is defined or used in a way that it is expected to hold a fixed value (like a constant or a number) but is also being treated as a date.
  There may be a misconfiguration in the calculation logic or in the data model where the same variable is being assigned or interpreted in conflicting ways.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Calculation Logic:
  
  Check the calculation logic where the variable "&1" is being used. Ensure that it is consistently defined as either a fixed value or a date, but not both.
  
  
  
  Check Data Types:
  
  Verify the data types of the variables involved in the calculation. Ensure that the variable is not being assigned a date value when it is expected to be a fixed value.
  
  
  
  Adjust Variable Usage:
  
  If the variable needs to be used as both a fixed value and a date in different contexts, consider creating separate variables for each purpose to avoid conflicts.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or help resources related to the specific module or functionality you are working with. This can provide insights into the expected usage of variables and calculations.
