Question 2 (20 marks) Suppose the raw data file Sales.txt (not provided) has already been referred to by the FILENAME reference 'DataB' in SAS Studio. You do not need to submit the FILENAME definition in your code.) The table below shows a subset of Sales. 1234567890123456789012345678901234567890 "David Wong" 1/Aug/2023 13200 "Brian Leung" 15/Sep/2023 23450 10/Sep/2023 33000 "Mary Chan" 3/Jul/2023 45600 20/Aug/2023 37800 1/Dec/2023 21500 30/Aug/2023 42000 "John Tam" 12/Sep/2023 35000 The first line in the shown table is not part of the data file. The records in the data set are grouped by the salesperson's name. The first record for each salesperson group includes the salesperson's name (at most 20 quoted characters, including the quotes and embedded blanks), the date of sales (dd/mon/yyyy), and the sales amount (standard numeric). The name field of the record always starts from the first column. Subsequent records of the same salesperson, if any, do not contain the name field. Each contains only the sales date (dd/mon/yyyy) and the sales amount (standard numeric). The sales date field in these subsequent records may begin in any column. All fields are separated by a blank space, and the data set does not contain empty fields. Note that each salesperson group may consist of one or more lines of records, and the same salesperson's records are not listed in date order. Write a SAS DATA step that reads each record of SalesRecords.txt into a SAS data set named Totalsales. The Totalsales must contain these features: It contains only one observation for each salesperson. It contains only the following variables: a salesperson's name without quotes, the salesperson's latest sales date in SAS date values, the number of days between the salesperson's latest sales date and the 31 of December 2023 (for example, if the latest sales date is 30/Dec/2023, then the number of days equal to 1)., the salesperson's total number of sales (equivalent to the salesperson's number of records in Sales), and the running total of sales for all salespersons. The columns can be arranged in any order. The following table shows a subset of Totalsales. The column headers shown in the table are for reference only. You don't need to define them in your SAS DATA step. You may name the variables in any way you want as long as they are meaningful and valid SAS variable names. You must accomplish the task with only one SAS DATA step. Using any other procedures is not allowed. Last sales date Number of sales Running sales total Days between last sales and 31 Dec 2023 Name David Wong 23223 Brian Leung 23268 Mary Chan 23345 John Tam 23265 13200 69650 216550 251550 152 107 30 110 (Hint: A SAS date value constant can be defined in SAS DATA step as 'dd/mmm/yyyy'd. For example, Var1= '1/jan/2023'd assigns a SAS date value constant to the variable Var1. The difference between two SAS date values (recent SAS date value - earlier SAS date value) returns the number of days between two dates.}
