Hi,

There is no official ServiceNow documentation that defines standard State and Stage combinations for REQ or RITM when multiple SCTASKs are involved. REQ, RITM, and SCTASK states are not automatically synchronized unless explicitly configured

For additional reference, the following community discussion explains the OOTB behavior and best practices around REQ/RITM state handling:
https://www.servicenow.com/community/sysadmin-forum/what-is-the-best-practice-or-guidance-on-the-sta...

If this helps, please give a like and mark it as a solution

Thank you
