  The SAP error message E1123, which states "Basic type does not exist: &", typically occurs when the system is unable to find a specified basic type in the IDoc (Intermediate Document) processing. This can happen for several reasons, and here are some common causes, solutions, and related information:
  Causes:
  
  Missing Basic Type: The specified basic type may not be defined in the system. This can happen if the IDoc type has not been created or activated.
  Incorrect Configuration: The configuration for the IDoc type may be incorrect, leading to the system not being able to locate the basic type.
  Transport Issues: If the basic type was recently transported from another system, it may not have been transported correctly or may not exist in the target system.
  Namespace Issues: If the basic type is in a different namespace and not properly referenced, the system may not be able to find it.
  
  Solutions:
  
  
  Check Basic Type Definition:
  
  Go to transaction code WE30 (IDoc Types) and check if the basic type exists. If it does not, you may need to create it or transport it from another system.
  
  
  
  Verify Configuration:
  
  Use transaction code WE20 (Partner Profiles) to ensure that the partner profile is correctly configured to use the specified basic type.
  Check the settings in transaction code WE81 (IDoc Types) to ensure that the basic type is correctly assigned to the IDoc type.
  
  
  
  Transport Check:
  
  If the basic type was recently transported, check the transport logs to ensure that it was successfully imported into the target system.
  If necessary, re-transport the object from the source system.
  
  
  
  Namespace Verification:
  
  Ensure that the basic type is in the correct namespace and that your configuration is referencing it correctly.
  
  
  
  Check for Typographical Errors:
  
  Ensure that there are no typographical errors in the basic type name in your configuration or IDoc processing logic.
  
  
  
  Related Information:
  
  IDoc Basics: Understanding IDocs and their structure can help in troubleshooting issues related to basic types. IDocs consist of segments, and each segment can have a basic type associated with it.
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific basic type or IDoc processing.
  Documentation: Refer to SAP documentation for IDoc processing and configuration for more detailed guidance.
