The following SERIES_FUNCTION_INFO calculates the monthly (frequency) average (value) of the DT_LOGGER_SERIES with LOGGER_SERIES_ID 32101231:

-60 seconds (dateOffset) is added to each derived DT_LOGGER_DATUM.DATUM_UTC_DT (e.g., 2019-07-01 00:00:00 becomes 2019-06-30 23:59:00), bringing the monthly average back into the month that it is for. (Note: This data is exported to DT_RESULT, which requires DT_SAMPLE and DT_TEST rows, and DT_SAMPLE.SAMPLE_DATE and DT_TEST.ANALYSIS_DATE are SMALLDATETIMEs, which are rounded to the nearest minute.)
After the agent has finished deriving the monthly averages, and added the derived data to DT_LOGGER_DATUM, it executes the equis.copy_logger_datum_to_result_temp_c stored procedure (exportSqlProcedure).
The equis.copy_logger_datum_to_result_temp_c stored procedure takes the input parameters that the Data Deriver Agent provides, and adds the additional input parameters that the equis.copy_logger_datum_to_result stored procedure needs.
The equis.copy_logger_datum_to_result stored procedure copies the derived data from DT_LOGGER_DATUM to DT_RESULT (and also to DT_SAMPLE and DT_TEST). A NULL value is allowed for some of its input parameters (e.g., FACILITY_ID and SYS_LOC_CODE are obtained from the series, or logger, row if they are NULL, and DT_RESULT allows a NULL value in RESULT_UNIT), however, not all parameters can be NULL (e.g., DT_RESULT does NOT allow NULL values in CAS_RN).
