  The SAP error message /STTPEC/MC_MD084 indicates that there is a conflict with the Global Trade Item Number (GTIN) and the serial number management settings for a specific material. This error typically arises in scenarios where the same GTIN is being used for multiple materials or when there is a mismatch in the serial number management configuration.
  Cause:
  
  Duplicate GTIN: The GTIN specified is already associated with another material in the system, which can lead to confusion in inventory management and tracking.
  Serial Number Management Mismatch: The material for which the GTIN is being used may have different settings for serial number management compared to the material that is already using the GTIN. For example, one material may be set to manage serial numbers while the other is not.
  Incorrect Material Master Data: There may be inconsistencies or errors in the material master data that need to be addressed.

  Consult with Master Data Management: If you are unsure about the correct GTIN or serial number management settings, consult with your organization's master data management team or SAP support for guidance.
