I've tried to do this using 2 fast lookups and then nesting one loop inside the other. The first lookup grabs a set selection of contacts and places into an sobject collection. The second grabs a set of account records and places into a separate sobject. I then start a loop through the contacts and a loop through the accounts. If that condition is true I go to the next contact. If false, it adds the record to new collection variable.
For me, I call that a "nested loop". What I'm finding is the inside loop the one through the accounts isn't restarting when I go back to next contact. I've turned on debug and I see the iteration of the account loop doesn't restart. My questions are: 1 is there a better way to do this type of check?
I want to be able to use nested loops in other items too and 2 is there a way to get the loop to restart from the original iteration. Restrictions: there will be more than records, so I will run into limits.
Here's an example of the flow. Please note that HH is the "account" object for me. When I put one of the Fast Lookups inside the Loop, it worked. Tim Shores 7 I ran into the same type of problem: inner loop does not happen after an initial iteration. I figured out that we aren't allowed to "break" out of a Flow Loop.This was one of the most popular sessions at TDX19 this year, with lines you only see at a rock concert. If you are building flows and missed this session at TDX19, you will want to read on and check out the recorded session below for some amazing demos that Alex created.
The web is full of rich web object and nested data models. They are responses you get when you make an API call. Many processes now require manipulation of such data types, and traditionally you would need to manually write Apex code and parse the complex data to pull them inside Salesforce.
Once the API is connected, the rest of the logic does not require any code. To enable access in Flow to this complex object, you need to go through a one-time setup:. Looping is another advanced feature in Flow that supercharges more advanced automation without writing code.
Looping lets you iterate an operation through multiple objects. The key to mastering looping is to understand the three underlying data structure components.
Choices are powerful elements within Flow that allow you to ask your users to provide input via a picklist, checking a box, or clicking on a radio button. For every question you display to your users, there is a frontend user input screen component and an associated choice data source in the backend. It becomes very confusing as to which data value to reference in the downstream actions. The key is to follow the flow of the data. The choice data you created in the backend feeds into the frontend screen components that surface the data to the user.
The piece of information you want to capture and pass downstream is what your user clicked on. To pass along that information, you need to reference the screen component, not the backend choice data. In his presentation, Alex walks through each frontend UI component and how the associated backend choice data works with it.
The rest of the minute session goes into details of other best practices, a powerful case management sample application built using Flow, and even a glimpse of the upcoming features in the product roadmap.

The only declarative clicks, not code automation tool that can stand up to the task is Flow Builder. As someone who identifies with an Admin, I have to admit, it took me a while to understand how to configure loops in flow. I hope these basic steps help you in understanding how to configure a basic loop.
Think of it as an assembly line. Every item going down the assembly line has the same actions taken on it. In the Salesforce world, if you have a group of records that you need to perform the same actions on for every record in this grouping would go through a loop. Each record, when it is its turn to go down the assembly line will be placed into a record variable, in my case, I call varLoopRecord.
This continues to happen until we are done with the last record in the collection and therefore, ends the loop. Start a loop path, iterating through the records in a collection variable. For each iteration, the flow temporarily stores the record in the loop variable in my example, varLoopRecord.
Often times, within a loop, you would want to make decisions and set certain values to fields in the loop record. A collection variable is a list of records you wish to take action on. A loop uses a loop variable to store the values for the current record in the collection.
When the loop completes taking action on the one loop record, Salesforce then places the next record into the loop variable.
Nested Loops in flow
To keep track of changes made along the loop path, add the loop record variable as a record to a new collection variable. One very important note: Avoid the bad Apex development practice of making a DML operation within a loop. This same limit applies to flows as well. Mary Markle is the Director of Operations. She would like to automatically update cases with a status of Escalated to a High priority and set the IsEscalated checkbox to true.
Solution: This blog post will just cover solution of getting the group of cases that have the Escalated status and taking action on those records. Select to create an Autolaunched flow. Next, we will use Get Records flow element to query the Case object to get all the records with the status of Escalated.
View image full screen. We will a Decision flow element to determine whether records were found in the previous step. If not records were found, the flow would fault when it get to the step in the flow where it tries to do things with the loop record variable — there is no record to work with!
Set the conditions to the following:. Which means, there is at least one record in the collection. We now need a Loop flow element where we will take each record in the Get Cases record collection variable to iterate through. Configure it as follows:.
For a loop record variable, we need an Assignment flow element to assign values to fields that we will update in this flow. View Image Full Screen.One last warning! You have two options here. Ready for the fun part? But unlike a decision, you are limited to two options. For the first example, we want to do a mass Opportunity Owner update of our large deal owners.
We create a Decision Element to sort through the Amount and determine who we will assign as the Owner of that Opportunity. Anytime you want to examine multiple records through a series of elements, you should use a Loop.
They would then be able to see a related list of opportunities in a multi-select pick list. The values selected in the multi-select picklist would form the SObject collection variable and then I would like to somehow extract the IDs of that collection variable and create a single record by populating up to 6 lookup fileds with these IDs.
The purpose of this is to be able to create an email merge document that needs to contain data from more than one opportunity. Like Like. Can you please post the assignment logic that you applied for second example. I have same exact requirement.
It keeps iterating the OpportunityAmount variable, and then you reference that later in your record update. Let me know if you need more help than that. You are commenting using your WordPress.

Can you please send me the assignment login for second example. Leave a Reply Cancel reply Enter your comment hereI often see many different posts around people not quite sure how to use a Loop in Salesforce. This could be for a few different reasons:.
If we have 20 records, by the end of the transaction this LoopCounter variable would equal If we had 10, it would equal This means, you need to be extra careful when dealing with potentially higher data volumes.
The value you use will vary based on how complicated your Loop is. You need to do some math to see the maximum number of records your Flow can take. I like to always go below that to be extra safe. You can exit mid-Loop through the records, once you hit a specific number that you want to Loop through. And just like that, we were able to count and tell if we were about to hit a limit.
Salesforce Flow Loop Inside A Loop
While this was all concept, did you catch an area I should have included into this? Hey David. Thanks for a great overview, and tip on the counter.

This SOQL queries limitation has been improved, prior to writing this blog I thought the limit was 50, but it seems Salesforce recently improved that limitation to So, keep your limits in mind when you begin to architect a solution like this.
I am going to give an outline of what each Element is doing, but I will only be focusing on the areas that are key to understanding how you can use a Loop inside of a Loop. Next, we need to now Loop between each of the Contacts that we have found with our Fast Lookup, so to do that we need to drag in our Loop. Now, this gets us to our Second Fast Lookup, which is where the magic happens.
In here, we simply need to take a step back and think about what we are trying to filter. Just like that, we are dynamically filtering this Fast Lookup for each Contact that comes into our Loop! Pretty simple, right? All that is left for us now is to setup our next Loop and talk about what we are doing there. So we just completed our Loop for the Campaign Memberships!
This is where we then repeat the process for every Contact that we had in our first Fast Lookup. Now, all that is left is for us to determine what happens at the end of our First Loop. In this scenario we want are sending them to a Fast Delete to get removed in bulk! Great, we are all set! Beware of the limits! You are commenting using your WordPress.

This allows your processor to address other tasks during the wait time. For now, just remember that it returns the list of records and field as given in the query.
If the result of the condition is true, the SQL statement will be executed. It has several uses. In most cases the outer loop is what causes the inner loop to execute. Having said that, even if you are someone who has recently started out working on Salesforce.
Before going through this below section, it will be better to go through my post on Salesforce Lightning Web Components Cheat Sheet to have overall idea for all types of properties, methods, event propagation etc.
Loop-powered devices are often much lower cost than other process control devices with built-in high power electronics. For example, the Do While Loop. Using multiple for loops one or more inside a for loop is known as a nested for loop. The Salesforce users can create Salesforce records using global actions—directly in their email applications.
Loops in a flow are created in two different ways. Flow diagram shows the preparation and action for drag-n-drop functionality component wise. But the variable declared in the parenthesis of a for loop, can only be used inside that for loop. Flow Instance. Static variables are local to the context of a Web request or test method during a call to runTestsso all triggers that fire as a result of a user's action have access to it. Let me know if you need more help on that.
Some options are replacing loops with maps wherever you can, using smaller batches, and inlining SQOL. We must ourselves put a condition explicitly inside the body of the loop and use the break statement to exit the loop. This is a very basic requirement. Judge every record whether it is in the specified date range.
It happens when a loop is encountered multiple times. How to input and print array elements? Array uses an index for accessing an element. The loop ran for two hours as specified by the timeout attribute in ISO format. That will skip the rest of the block and won't check the condition again. If any SQL statement exists outside the loop, it will be executed. Create two account records as a prerequisite Name: a1; Employees: 1 Name: a2; Employees: 2 2.
Endless Loop. A set of speed was selected ranging from rpm to rpm. Usage Notes. Issue is if customer is not found I am not able to use Flow Decision activity to switch the flow to beginning increasing the record count by 1. A closed-loop cooling system can exchange heat with the main cooling water system in conventional tube and shell heat exchangers or plate and frame heat exchangers.
For this to work, all of the files would need to reside in the same directory structure either locally or on the networkand they must all have the same structure and metadata.
