• What is the cause and solution for SAP error message CNV_DMC_SIN305 - Value &1 of field Customer will be reset as item categ is not Third Party ?

  The SAP error message CNV_DMC_SIN305 indicates that there is an issue with the configuration of the item category in a sales document, specifically related to the Third Party process. This error typically arises during data migration or when processing sales orders that involve customer-specific settings.
  Cause:
  The error message states that the value of the field "Customer" is being reset because the item category is not set to "Third Party." In SAP, Third Party processing is a specific sales process where the vendor ships the goods directly to the customer, and the seller does not handle the inventory. If the item category is not configured correctly to support this process, the system will not allow the transaction to proceed, leading to this error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Item Category Configuration:
  
  Go to the configuration settings for item categories in the SAP system (Transaction code: OVA2).
  Ensure that the item category you are using is set up for Third Party processing. The relevant settings include:
  
  The item category must be marked as a Third Party item category.
  Check the settings for the item category in the sales document type to ensure it allows Third Party processing.
  
  
  
  
  
  Review Sales Document Type:
  
  Ensure that the sales document type being used is configured to allow Third Party processing. This can be checked in the configuration settings for sales document types (Transaction code: OVA2).
  
  
  
  Check Customer Master Data:
  
  Verify that the customer master data is correctly set up for Third Party transactions. This includes checking the sales area data and ensuring that the customer is allowed to be used in Third Party sales.
  
  
  
  Data Migration Settings:
  
  If this error occurs during data migration, review the mapping and transformation rules in the migration tool (such as SAP S/4HANA Migration Cockpit or SAP Data Migration Cockpit) to ensure that the item categories are correctly assigned.
  
  
  
  Testing:
  
  After making the necessary changes, perform a test transaction to ensure that the error no longer occurs.
