• What is the cause and solution for SAP error message E1122 - Basic type exists ?

  The SAP error message E1122, which states "Basic type exists," typically occurs in the context of IDoc processing or when working with data types in SAP. This error indicates that there is an attempt to create or modify a basic type that already exists in the system.
  Cause:
  
  Duplicate Basic Type: The most common cause of this error is that a basic type with the same name already exists in the SAP system. This can happen if you are trying to create a new basic type that has the same name as an existing one.
  Transport Issues: Sometimes, if you are transporting objects between different SAP systems (e.g., from development to production), there may be conflicts if the same basic type exists in both systems.
  Namespace Conflicts: If you are working in a namespace and trying to create a basic type that conflicts with an existing one in the same or a different namespace, this error may occur.
  
  Solution:
  
  Check Existing Basic Types: Before creating a new basic type, check the existing basic types in the system. You can do this by navigating to the relevant transaction (e.g., WE30 for IDoc types) and searching for the basic type name.
  Rename the New Basic Type: If you find that the basic type already exists, consider renaming the new basic type you are trying to create to avoid the conflict.
  Modify Existing Basic Type: If the existing basic type meets your requirements, you may choose to modify it instead of creating a new one.
  Transport Management: If the error arises during a transport, ensure that the transport requests are correctly managed and that there are no conflicts between the source and target systems.
  Namespace Management: If you are working with namespaces, ensure that you are using the correct namespace and that there are no conflicts with other namespaces.
  
  Related Information:
