Data Quality Advisories

The advisories listed in the table below impact the quality of data in the Data Warehouse. Users should be aware of potential issues with data quality when reporting on elements listed in these advisories.

Data quality issues can originate from many sources and can arise as the result of a variety of circumstances. Human error in data entry, discrepancies in the source system, or errors during processing into the Data Warehouse are all possible causes of data quality issues.

The information below is intended to identify what the issues are, when a user may encounter them in the EDW, and what actions a user can take to mitigate any discrepancies in reports or analysis.

T_ADDR_AUD_HIST   The Banner source system (table SPRADDR) allows updates without making changes to the timestamp on the record. The EDW is expecting the timestamp to be updated in order to pick up any changes. We are working with the appropriate groups to address this issue.
Data Collection: Finance and HR
N/A N/A Banner users should be aware of a potential issue involving labor encumbrances and carefully monitor their funds during the fiscal year end closeout process. For more information, see the OBFS notice.
Data Collection: Finance
T_AR_TRAN   At times, an accounts receivable transaction occurs before the customer's general student record is created. The Data Warehouse processing does not update the rows in AR_TRAN or perform additional history tracking. (The Data Warehouse processing writes the row with the information available at the time.) This causes an occasional mismatch between Banner and the Data Warehouse.
T_CMDTY_CD EDW - Finance - Fixed Assets This table may contain similar commodity codes (one with, and one without a leading space) that have different descriptions. More...

1. This table may contain inaccurate or incomplete primary job indicators.

2. A timing issue exists with this table. It is a history tracking table, therefore rows that have an effective date after midnight are not loaded. This is done to ensure the new rows are added on the correct day. A problem occurs because the new Labor Distribution Row expires the old row. The effect is that the individual will not have any active Labor Distributions until the next day when the new Labor Distribution is added.

T_OL_EXPS_SRC_DETL EDW – HRFIN BOS Expenses The table T_OL_EXPS_SRC_DETL combines the data from T_OL_DETL (Operating Ledger), T_PAYR_ACCTG_DETL (Payroll Accounting Detail), and T_PCARD_TRAN_DETL (PCard Transaction Detail) to break out the details of payroll and PCard expenses that are stored at a summary level on the operating ledger. When an expense is a payroll or PCard expense on the operating ledger, the ETL process refers back to the payroll or PCard tables and displays the individual transactions that make up the expense.
Because of Banner processing, there are instances when the individual transactions cannot programmatically reconcile to the summary line item. The current instances can be viewed by clicking here.

T_SECT_DEPT_RESTRICT_HIST   This table in the Data Warehouse is missing several rows because of a record type mis-match
T_SECT_RESERV_SEAT_HIST   Several rows of data are not posting to this table in the Data Warehouse because of a defect in Banner on the Activity Date. No timeframe has been established for a resolution.
T_STUDENT_OVERALL_CRS_DETL EDW - STU - Academic Records This table contains only 10 years of academic history information. If you are interested in data older than 10 years, you need to use Institutional and Transfer Course information (Tables: T_STUDENT_AH_CRS, T_TFER_INST, T_TFER_CRS, T_EQ_UI_CRS).

T_ACTV_LOG   Some of the special characters in the source data for the T_ACTV_LOG.ACTV_DESC field are unrecognized characters and are being translated into ¿. When data is transformed from DSSTAGE into DSEDW, where there is now ¿, one or more characters at the end of the string is getting truncated
