UI Policiesin ServiceNow dynamically control form field behaviorswithout scripting. They help maintaindata consistencyand improve user experience.
B: Setting fields hidden
UI Policies canhideform fields based on conditions.
Example: Hide the"Resolution Notes"field unlessState = Resolved.
D: Setting fields read-only
UI Policies canmake fields read-onlyto prevent users from modifying certain data.
Example: Set"Requested For"fieldread-onlyafter submission.
E: Setting fields mandatory
UI Policies canenforce mandatory fieldsbased on conditions.
Example: Make the"Justification"field mandatory ifPriority = High.
A: Setting fields to accept the data with 'n' number of characters
Field length restrictions are set in theDictionary Definition, not UI Policies.
C: Setting fields to accept the data in an expected format
Data formatting (e.g., date, phone number) is controlled byField Types and Data Policies, not UI Policies.

InServiceNow Import Sets,coalescingis the process ofmatching existing recordsto avoid duplicate entries when importing data.Conditional coalesceis the only method that allows using ascriptto determine if records should be updated or inserted.
Single-field Coalesce (Incorrect)
Usesone fieldto determine if a record exists.
If a match is found, the record isupdated; otherwise, a new record is created.
Example: Usingemailas a coalesce field when importing user data.
Multiple-field Coalesce (Incorrect)
Usesmultiple fieldsto find a match.
If all specified fields match, the record isupdated. Otherwise, a new record is created.
Example: MatchingFirst Name + Last Name + Email.
No Coalesce (Incorrect)
Every import creates anew record, regardless of whether a similar record exists.
Conditional Coalesce (Correct)
Allows using ascript to define custom logicfor identifying records to update.
This isthe only coalescing method that supports scripting.
Example:
A script can check if eitheremailoremployee IDexists, andif neither exist, create a new record.
