Identify the Records That Need to Be Exchanged
Begin with work that is repeated. Finance may need payroll costs by department while HR already holds the calculation results. Agree the information to send, the period it covers, and who will check it. Exchange the records required for that purpose.
We review practical examples and required formats. Agree which application holds the primary record so changes are coordinated. If department codes differ between systems, map them before the connection enters use.
