• What is the cause and solution for SAP error message CL618 - Material "&" already created ?

  The SAP error message CL618 indicates that a material with the specified identifier (represented by "&") has already been created in the system. This error typically occurs when you attempt to create a new material that has the same material number as an existing one.
  Cause:
  
  Duplicate Material Number: The most common cause of this error is that the material number you are trying to create already exists in the system.
  Incorrect Input: There may be a typographical error in the material number you are entering, leading to confusion.
  Material Creation Process: The process for creating materials may not have been followed correctly, leading to an attempt to create a duplicate.
  
  Solution:
  
  
  Check Existing Materials: Before creating a new material, check the existing materials in the system to confirm whether the material number you are trying to use is already in use. You can do this by using transaction codes like MM03 (Display Material) or MM02 (Change Material).
  
  
  Use a Different Material Number: If the material number is indeed already in use, you will need to select a different, unique material number for your new material.
  
  
  Review Material Creation Process: Ensure that you are following the correct steps for creating a material in SAP. This includes using the appropriate transaction code (e.g., MM01 for creating a material) and entering all required fields correctly.
  
  
  Check for Deactivated Materials: Sometimes, materials may be deactivated rather than deleted. If you are trying to create a material that has been deactivated, you may need to reactivate it instead of creating a new one.
  
  
  Consult with Your SAP Administrator: If you are unsure about the existing materials or the creation process, consult with your SAP administrator or a colleague who is familiar with material management in SAP.
