Creating a report of "what's missing".

//First we define the output text if an item is missing
var text application=If(IsNull([Application]),"Application","");
var text signedPD=If(IsNull([Signed PD]),"Signed PD","");
var text cbcForm=If(IsNull([CBC Form]),"CBC Form","");
var text dualEmployment=If(IsNull([Dual Employment]),"Dual Employment","");
var text trainingCert=If(IsNull(),"Training Cert","");

//Next we define if there are missing items
var bool missingItems=$application <>"" or $signedPD <>"" or $cbcForm <>"" or $dualEmployment <>"" or $trainingCert <>"";

//Next we define an optional text value to describe what the items are that will list
var text prefix=If($missingItems=true,"Missing Items: ","");

//Now we list all the "missing" items in a simple-list formula
List("\n",
$missing,
$application,
$signedPD,
$cbcForm,
$dualEmployment,
$trainingCert
)​

Then add this formula-text field to your report with the Hiring Manager as a separate column against your list of employees.
