def REQUIREDSCANTYPE = 33604 as long
def NEXTFULLSTATICSCANDUE = 28546 as long

//get Custom Field value

def RequiredScanTypeCustomField = CustomFieldManager.getCustomFieldObject(REQUIREDSCANTYPE)
def RequiredScanTypeValue = issue.getCustomFieldValue(RequiredScanTypeCustomField)

def NextFullStaticScanDue = CustomFieldManager.getCustomFieldObject(NEXTFULLSTATICSCANDUE)
def NextFullStaticScanDueValue = issue.getCustomFieldValue(NextFullStaticScanDue) as Date

//Today date
def today = new Date()

//LOGIC for Required Scan type
if (RequiredScanTypeValue == 'Static Scan'){
NextFullStaticScanDue(before.(today))
}
else{
throw new InvalidInputException("Static Scan must be vaild")
}
