The Process Controls that should be enforced through the front end application system, to have consistency in the control process are as follows:

Run-to-Run Totals: It focuses on verifying data through different stages. A specific record can be used to maintain the control total.

Reasonableness Verification: Two or more fields can be compared and cross verified to ensure their correctness.  

Edit Checks: Edit checks similar to the data validation controls can also be used at the processing stage to verify accuracy and completeness of data.

Field Initialization: Data overflow can occur, if records are constantly added to a table or if fields are added to a record without initializing it .

Exception Reports: Exception reports are generated to identify errors in data processed.

Existence/Recovery Controls: The check-point/restart logs facility is a short-term backup and recovery control that enables a system to be recovered if failure is temporary and localized.
