Is there a way to make charge account field un editable for Change orders but editable for create pu

Content

Hello Team,

 

Hope you are doing well.

 

Requirement : In our current project we have a requirement of making charge account uneditable for a change order (Via Manage requisitions as well as Manage Orders page), but charge account should be editable while creating a purchase order.

 

Research Done : We stumbled upon a document PRC:SSP:How to Make The Charge Account Attribute on a Requisition Read Only? (Doc ID 2541184.1) that showed how to make charge account field uneditable for change orders via sandbox, but as a consequence to that, the charge account field in create order also becomes uneditable, which is not desired.
