Re: How to rename a req name by adding the req ID?
I don't have scripts for this. You will need to develop them yourself. All the information you need about workflow customization is in the Administrator Guide. Information about the API is available in the OTA API reference. Both documents are in the Documentation Library.
What the Post method does is commit your changes to the database. For values that are normally set manually through the UI, you still have to set those values before using the Post method.
