  The SAP error message L2146, which states "Dest. data is the same as the Source data in all fields," typically occurs during the process of data transfer or when trying to create a new record that is intended to be different from an existing one. This error indicates that the destination data you are trying to create or modify is identical to the source data in all relevant fields, which is not allowed.

  Solution:
  
  Check Data: Review the source and destination data to ensure that they are indeed different. Make any necessary changes to the data in the destination fields.
  Modify Input: If you are manually entering data, ensure that you are not duplicating the source data in the destination fields.
  Adjust Mapping: If you are using a data transfer tool, check the mapping configuration to ensure that the fields are correctly set up to avoid transferring identical data.
  Use Different Values: If you are trying to create a new record, ensure that the values in the destination fields are unique and do not match the source data.
