I have created KUT field with text 40. From C4C UI , I can update the value and save it.
For my requirement i am trying to update KUT Value from SDK in script ( validation -onsave).
I have the reference hence i can read the file but while updating i am getting error that this KUT field is read only.
Code in the script is very simple
this.kut_field = "updated field value" .
