How to automatically update revision letter in Sharepoint list

[jstfmc1]

Hello,

I have a relatively simple task of using flow that once an email is received, the document status is updated but I also need the revision letter of the document to automatically raise one letter high (i.e. from A to B). I have not been able to find an example flow in the forums so I apologize if I missed it.

See example flow:

I agree that this should be simple but there are no expressions in Flow that facilitate your requirement.  My suggestion is to create a SharePoint list and use it as a reference.  Have two columns - current and next. 

Current  Next

A             B

B             C

and so on.....

Lookup the row that has the current revision letter and use the character in the Next column when updating the SharePoint list.

Let me know if you need an example.

Scott,

Thanks a lot, that's a great workaround! Just to capture for those who are wondering how I set it up, here is the screen shot after creating a second list to reference on the same Sharepoint:

It's possible there is a cleaner way to set this up but it works as intended.

Thanks again.
