Key notes

Some of our readers have recently reported that while writing and testing some codes, they encountered the apex CPU time limit exceeded error message.

Salesforcehas a timeout limit for transactions based onCPU usageand once reached this error message comes up. In this article, we will discuss how to fix this issue.

What causes Apex CPU time limit exceeded error?

There can be several reasons why you are experiencing the apex CPU time limit exceeded error. Below are some of the potential reasons:

Since you now know some of the possible reasons behind the apex CPU time limit exceeded error, let us proceed to how you can fix this problem.

How can I fix the apex CPU time limit exceeded error?

Before trying any of the advanced solutions provided in this article, whenever you encounter the error, try to perform the following preliminary checks:

Having tried the above checks, and the issue persists, you can now explore the advanced solutions provided below.

1. Set LoggingEnabled to False

The LoggingEnabled setting uses more processing power than is necessary for day-to-day operations. Changing the settings to false reduces the likelihood of receiving the apex CPU time limit exceeded error.

2. Use Salesforce Flow instead of Process Builder

Process builder processing is reported by many users to always trigger the apex CPU time limit error.

According to Salesforce, process builders and workflow should not be used for automation, but usingSalesforce Flowcan save users from CPU timeout errors.

3. Use Map-based queries

To avoid extra loops, use map-based queries. Below is an example of a map query used for loop to get record ID which increases the CPU time:

List accList=[Select Id,Name from Account limit 100]; Set setIds=new Set(); for(Account acc: accList){ //More CPU time for sure due to looping setIds.add(acc.id); }

Using Map query saves the CPU a great deal of time and it has proven to be one of the best solutions for the apex CPU time limit exceeded error.
