Q:

How can I improve this on hold question to make it fit the requirements of this stack? 

I have a question about my The Workplace Stack Exchange post: How to tell someone politely that they are barking up the wrong tree? 
The question is put on hold, how can I improve it? 

A:

The best way would be to give a bit more detail, use more professional terminology, explain things a bit, and state your goal clearly. 
You posted:

R&D: MIS, something wrong, please rectify. 
MIS: HR, MIS need to XYZ, please advise. 
HR: Hi Finance, please advise so MIS can proceed to solve the issue. 
R&D: MIS, is this issue resolve? 
Everyone is in the email loop. 
It's pretty easy to tell it's pending for response from Finance, but R&D asking for response from MIS instead.  
How do MIS tell R&D politely that they are barking up the wrong tree? 

You might want to do something like this. 
How do I point out, in a professional manner, that someone in an email chain has made a mistake? 
then, go on like this. 
R&D sent us an email, and included HR & finance.   HR responded and instructed finance to authorize payment so that we could proceed.  
R&D followed up in the email chain asking if we had resolved the issue before Finance had even responded. 
How can I politely inform the person in R&D that we are still waiting for a response.
