- modify the BIR report script for extracting the accumulating total sales per day and per POS for the field of beginning and ending balance
- test and compare the data into the should be data from finance and the output still not tally with the should be data
- re-modify again the script and ask Mark for help for extracting of the data
- Mark gave a script, test the script and still not extracting the correct data
- modify the script until it returns a correct data
- after modifying the script many time the output is now tally with the should be data from finance
- apply the modified script into the BIT reports and test the reports
- upon testing, I encounter an error, fix the error to generate a report
- after fixing the error another error encounter
- fix all the error encounter until the report generated an excel file
- check the excel file and compare into the should be data
