• What is the cause and solution for SAP error message CNV_20900011 - Merge to vendor &1 is not supported ?

  The SAP error message CNV_20900011 indicates that a merge operation for a vendor (in this case, the vendor identified by &1) is not supported. This error typically arises during data migration or conversion processes, particularly when using SAP's tools for data migration, such as the SAP S/4HANA Migration Cockpit or other data conversion tools.
  Cause:
  
  
  Unsupported Merge Operation: The error suggests that the system does not support merging the specified vendor with another vendor. This could be due to various reasons, such as:
  
  The vendor is involved in transactions that cannot be merged.
  The vendor has specific attributes or configurations that prevent merging.
  The merge operation is not allowed due to business rules or system settings.
  
  
  
  Data Integrity Issues: There may be data integrity issues that prevent the merge, such as existing open transactions, purchase orders, or contracts associated with the vendor.
  
  
  Configuration Settings: The system configuration may not allow for certain types of merges, especially if they violate business logic or compliance requirements.
  
  
  Solution:
  
  
  Check Vendor Status: Review the status of the vendor in question. Ensure that there are no open transactions, purchase orders, or contracts that would prevent the merge.
  
  
  Review Merge Criteria: Ensure that the criteria for merging vendors are met. This may involve checking the attributes of the vendors to be merged and ensuring they are compatible.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion tool you are using. There may be specific guidelines or limitations regarding vendor merges.
  
  
  Use Alternative Methods: If merging is not supported, consider alternative methods for consolidating vendor data, such as:
  
  Manually updating records to reflect the desired state.
  Using data cleansing tools to prepare the data before attempting a merge.
