How to make catalog form as ready only after task status changed to closed complete.

[Deepika43]

In my requirement need to make the catalog form to be closed complete after task status was changed to closed complete. 
In detail, If the approval is approved. It will create catalog task with status closed complete. Next, step should be once the catalog task was created with closed complete the catalog form should be read only.

I used client script for this but not working. Here I attach the screenshot of the script. 

Please suggest is any other method. 
If UI policy means no. I will affect globally. Only for x catalog item this should be done.

Hi @Deepika43,

Make sure that values for close complete is correct and

Syntax:

 g_form.setReadOnly('field_name', true/false);

I would suggest to use UI policy with needed conditions and add fields with Read only as true.

If my response helps to solve your issue. Kindly mark it as helpful & correct. It will be helpful for future readers! 👍🏻
Thanks,

As mentioned UI policy is the only solution for this.
