  The SAP error message RMSL_WUI355, which states "This item number is already in use," typically occurs in the context of SAP Retail or SAP S/4HANA when you are trying to create or modify an item (such as a material or product) that already exists in the system. This can happen in various scenarios, such as when you are trying to create a new article in the Article Master or when you are attempting to upload data related to items.
  Cause:
  
  Duplicate Entry: The item number you are trying to use is already assigned to another item in the system.
  Data Upload Issues: If you are using a data upload tool (like LSMW or a custom program), it may be trying to create an item that already exists.
  Incorrect Item Number: You may have mistakenly entered an item number that is already in use.
  
  Solution:
  
  Check Existing Items: Verify if the item number you are trying to create already exists in the system. You can do this by searching for the item in the relevant transaction (e.g., MM03 for Material Master).
  Use a Different Item Number: If the item number is indeed in use, consider using a different, unique item number for your new entry.
  Review Data Uploads: If you are performing a bulk upload, ensure that your data does not contain duplicates. You may need to clean your data file to remove any duplicate item numbers.
  Consult with Your Team: If you are unsure about the item number's status, consult with your colleagues or the team responsible for item management to clarify the situation.
  Check for Active Status: Sometimes, an item may be inactive or archived, but still, the system may not allow you to reuse the number. Check the status of the existing item.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM01 (Create Material), MM02 (Change Material), and MM03 (Display Material) to manage item numbers effectively.
  SAP Notes: Check SAP Notes for any known issues or updates related to this error message. SAP Notes can provide additional context or solutions.
