Have you ever noticed that Power Automate will sneak in that ‘Apply to each loop’ even though you are only expecting a single value.
For example this can happen whenever you are using a Action that ‘Lists’ items, folders, fields, etc.
In this example I will be showing how to get a User ID in CDS with the users Full Name.
Power Automate creates a ‘Apply to each’ loop when selecting dynamic content from a action that Lists items, folder, or anything. In most cases this is awesome and creates a nice smooth workflow.
However, what about when you know exactly what you want to look for and you know its only going to be 1 record, item, whatever is going to be returned. Power Automate will still make you use the ‘Apply to each’ loop.
This may not be a such a terrible thing, but if you need to do multiple things underneath that action, you will have to put them in the loop as well (if you need any data or reference to that action)
On to the magic..
In my example Flow I will be using:
- ‘Compose’ action to have my Full Name stored.
- ‘List records’ CDS action to list records from the default Users table entity.
** Note – This can be done with any connector. **
- ODATA filter on the ‘List records’ which I am using to filter ‘fullname’
- Under the ‘List records’ I use a ‘Compose’ action to store the users ID(Primary Key from CDS) and the users Email Address
Step 1 – I am using CDS List records for my example, with a Odata filter
Step 2 – Adding Compose action to use the Expression to bypass the loop
This is the exact expression I used in my Compose action
The only thing you have to watch out for is when there is a empty record. This will cause an error if the record is empty.
This can easily be fixed using a Condition If block before the Compose to check if value is empty using the empty() expression.
If you want to avoid the error altogether, you can use the expression first() instead of body()
I hope anyone finds this useful. This boosts performance greatly when you only need one record since you wont need a Apply to each loop.
