Since you are talking about a Rate, then the PCR must be for Payroll processing.
for the first queries, you should be able to create the appropriate decision tree with operation OUTWP (such as OUTWPPERSB or OUTWPSHIFT) while the last decision on the Hire Date could be achieved through operation RTE (or NUM, or AMT).
Note that there are many threads on Payroll PCRs related to Dates from IT0041. Please do a little search, or use the Operation's documentation.
