+Using current.update() in Business rule is not recommended from servicenow due to following reasons-
+1. Before- Records will be saved automatically after BR executes so using current.update is redundant
+2. After- Triggers all "before" BRs again causing recursion calls and performance issue
+3. Async- Same issue as in After
+4. Query- current object doesn't exist and will cause error
+5. Display- Runs before UI is rendered. Using current.update doesn't make sense.
+
+To avoid such scenarios, a business rule can be configured on the 'sys_script' table will trigger an error message and
+block the creation of any new business rule if it detects the use of current.update() within the script.
+
+Runs: onBefore insert.
