Processing of this record is rejected as a result of this error
handling. In particular, no source data records or related target data
records could be determined.

to the design rules described in the following SAP Notes:
Start routine: SAP Note 1258089
End routine: SAP Note 1223532

If record numbers are created without a reference to a source record,
this always results in the load process terminating if there is an
error.

• What is the cause and solution for SAP error message RSM2720 - Record (&1) for segment (&2) has no reference to a source record ?

  The SAP error message RSM2720 indicates that there is a problem with the data in the context of the data transfer process, particularly when dealing with the Data Transfer Workbench (DTW) or during the loading of data into the SAP system. The message states that a record for a specific segment does not have a reference to a source record, which means that the system is unable to find the necessary source data that should correspond to the record being processed.
  Cause:
  
  Missing Source Record: The most common cause of this error is that the source record that the segment is supposed to reference is missing or has not been loaded into the system.
  Incorrect Mapping: There may be an issue with how the data is mapped between the source and target systems. If the mapping is incorrect, the system may not be able to find the corresponding source record.
  Data Integrity Issues: There could be data integrity issues where the records are not properly linked or related in the source data.
  Sequence of Data Loading: If the data is loaded in the wrong sequence, it may lead to situations where a record is trying to reference another record that has not yet been loaded.
  
  Solution:
  
  Check Source Data: Verify that the source data is complete and that all necessary records are present. Ensure that the record referenced in the error message exists in the source data.
  Review Mapping Configuration: Check the mapping configuration to ensure that it correctly reflects the relationships between the source and target records. Make sure that all required fields are correctly mapped.
  Load Order: Ensure that the data is being loaded in the correct order. For example, if you are loading master data and transactional data, make sure that the master data is loaded first.

  Consult Documentation: Refer to SAP documentation or guides related to the specific data transfer process you are using, as they may provide additional insights or troubleshooting steps.
