• What is the cause and solution for SAP error message MC152 - Incorrect parameter & ('&' not allowed) ?

  The SAP error message MC152 ("Incorrect parameter & ('&' not allowed)") typically occurs in the context of the SAP Material Management (MM) module, particularly when dealing with the configuration of certain parameters or settings in the system. This error indicates that an invalid character, specifically the ampersand (&), has been used in a parameter where it is not allowed.
  Cause:
  
  
  Invalid Character Usage: The most common cause of this error is the inclusion of the ampersand (&) character in a field or parameter that does not accept it. This could happen in various scenarios, such as:
  
  When defining a selection parameter in a report or transaction.
  When entering data in configuration settings or customizing transactions.
  In user-defined fields or custom programs where the input is not validated properly.
  
  
  
  Data Entry Errors: Users may inadvertently enter the ampersand character while filling out forms or input fields.
  
  
  Solution:
  
  
  Check Input Fields: Review the input fields or parameters where the error is occurring. Ensure that the ampersand character is not present. Remove it if found.
  
  
  Validation of Configuration: If the error arises from configuration settings, check the relevant configuration transactions (e.g., SPRO) to ensure that no parameters contain invalid characters.
  
  
  Review Custom Code: If the error is triggered by a custom program or report, review the code to ensure that it properly handles input validation and does not allow invalid characters.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for the specific transaction or module you are working with to understand the valid input formats.
  
  
  Testing: After making corrections, test the transaction or report again to ensure that the error has been resolved.
