• What is the cause and solution for SAP error message EG068 - Material must be unique when you specify serial numbers ?

  The SAP error message EG068 ("Material must be unique when you specify serial numbers") typically occurs in scenarios where you are trying to process materials that have serial numbers, but the system requires that the material number be unique for the serial number being entered. This error is common in transactions involving goods movements, deliveries, or inventory management where serial numbers are involved.
  Cause:
  
  Non-Unique Material Numbers: The error arises when you attempt to enter multiple items with the same material number while specifying serial numbers. SAP requires that each serial number corresponds to a unique material number.
  Incorrect Configuration: The configuration settings in the material master or serial number management may not be set up correctly, leading to conflicts.
  Data Entry Errors: There may be a mistake in the data entry where the same material number is being entered multiple times for different serial numbers.
  
  Solution:
  
  Check Material Numbers: Ensure that each serial number you are entering corresponds to a unique material number. If you are trying to enter multiple serial numbers, make sure they are associated with different materials.
  Review Serial Number Assignment: Verify that the serial numbers you are trying to assign are not already assigned to another material or that they are not duplicated in your entry.
  Material Master Configuration: Check the configuration of the material master records to ensure that they are set up correctly for serial number management. This includes checking the settings for serial number profiles and ensuring that the materials are marked for serial number tracking.
  Use the Correct Transaction: Make sure you are using the appropriate transaction for the operation you are trying to perform. Some transactions may have specific requirements regarding serial numbers and materials.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling serial numbers and materials in your version of SAP.
