We have created a custom process for New Hire form. This form contains few fields of IT0002 like Last name, First name , DOB and SSN as mandatory fields. If the user fills the entire form on portal and leave the last name field as blank, then the system throws error as "No Data Available for A XXXXXXXX 0002" and "Last Name - Fill in all required fields". After the data is being updated in this field then the "Previous" "Next" "Close" and "Save Draft" button all of them become non-responsive. Due to this , we are stuck at the initial step of the process and cannot proceed further.
