6R021 - Details

• The SAP error message 6R021 ("Cannot create initially, data already exists") typically occurs when you are trying to create a new entry in a table or a master data record, but the system detects that an entry with the same key or identifier already exists. This can happen in various contexts, such as when creating a new customer, vendor, or material record.
  Causes:
  
  Duplicate Key: The most common cause is that the key (like a customer number, vendor number, or material number) you are trying to create already exists in the database.
  Data Migration Issues: If you are migrating data from another system or performing a mass upload, there may be existing records that conflict with the new entries.
  Incorrect Input: The input data might be incorrect or not formatted properly, leading the system to misinterpret it as an existing record.
  
  Configuration Issues: There may be configuration settings in the system that enforce unique constraints
