!!!FAMILIES FIRST CORONAVIRUS RESPONSE ACT POLICY (2020) A Change Reason code is the rationale as to why information has been created or changed as of an effective date. The change reason, a user-defined table, allows users to track why an effective date change is made to an employee’s record or to a code definition form. Each change reason may be restricted by function, by adding functions to the usage area, at the bottom of the screen. Adding a function-change reason usage will restrict the function indicated to have the change reasons shown. This may also be seen and maintained through the Maintain Functions form ([IMFN]). Once a function has restricted change reasons applied, then that function will see only those change reasons. If there is no restriction applied to a function's change reasons, then all change reasons will be presented.
