We have created one form and it contain 10 variables. 5 variables are filled at the time of creating the request. Once it is approved by the line manager it will create the catalog task1, in this task group owner need to fill the 3 variables. In this task 5 variables are read only. Once this task it is closed it will create other task2 requesting the group owner to fill other 2 variable. In this task2 previously filled 3 variables should be in read only. once task2 is closed it will create task 3 and all the variables should be in readonly. Please help me how to achieve this.
