List Edit in Sc_task table for RequestState field getting " security prevents writing to this field

[MThomas1]

Field name trying to bulk list edit = Request State.

I applied a filter to SC_Task table and able to get associated REQUEST State field . But when trying to update the field value , getting " Security prevents writing to this field"  message. Other fields are allowing to listedit on sc_task table.

But  I am able to list edit same field from sc_request table.

what could be restricting the list edit for the request state filed in sc_task table?

Thank you and appreciate your guidance on the request.
