  The SAP error message UPO_MIG387, which states "Measurement &1 already mapped to tank parameter," typically occurs in the context of the SAP Environment, Health, and Safety (EHS) module or when dealing with tank management in SAP. This error indicates that there is an attempt to map a measurement (like a sensor reading or a measurement point) to a tank parameter that has already been mapped to another tank parameter.

  Configuration Issues: There may be issues in the configuration of the tank parameters or measurement points that lead to conflicts.

  Remove Duplicate Mapping: If the measurement is indeed mapped to another tank parameter and you want to change it, you will need to remove the existing mapping before you can map it to a new parameter.
  Correct Data Migration: If this error occurred during a data migration process, ensure that your data does not contain duplicates. You may need to clean up the data before re-attempting the migration.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on mapping measurements to tank parameters, as there may be additional steps or considerations based on your specific SAP version or configuration.
