Allow only 1 instance of a flow to run at the same time

Hello all, I would like to know if there is a way to avoid the same flow to run while there is another instance of this same flow already running.

This is because I've noticed that when 2 or more instances of the same flow are running at the same time, the data manipulation that it's performing turns into a "complete mess". This does not happen if I wait for the running flow to complete before starting a new one. 

However, this limitation is very bad because I want to be able to share the flow w/ other people and they will eventually start it at the same time and the final result would be incorrect.


Basically, my flow (manually triggered) extracts some data from SQL DB (Azure), then I use an Excel template file (stored in my OneDrive for Business) w/ a table in order to be populated w/ the data from SQL. For this step, I have to first list all the rows in the table and then I loop through it and delete them all before I add the new rows that are coming from SQL.

After that, I inserted a 1-minute delay before getting the file contents /metadata and then send the excel file by email.


See the setup of my flow attached. 


I appreciate some help - as I said, what I want is to avoid this flow to be initiated at the same time because if it happens, my excel template file turns into a mess (conflicting/incorrect information is sent by email probably because one instance of the flow is inserting rows at the same time or removing rows at the same time of the other and vice versa)Setup of my flowSetup of my flow




Thanks, Daniel
