Salesforce’s Data Manipulation Language (DML) operations are crucial for managing data within the platform. However, these operations are subject to various limits imposed by Salesforce. Understanding and managing these limits is essential for maintaining efficient and effective Salesforce implementations. In this comprehensive guide, we’ll explore Salesforce DML limits, their significance, best practices for staying within limits, and provide FAQs and external resources for further insights.
Understanding Salesforce DML Limits
What are DML Limits?
Salesforce imposes limits on the number of Data Manipulation Language (DML) operations that can be performed within a single transaction. These operations include inserts, updates, deletes, and undeletes of records in Salesforce objects.
Why are DML Limits Important?
DML limits ensure the stability and performance of the Salesforce platform by preventing excessive resource consumption and maintaining system performance for all users. Staying within these limits helps avoid performance degradation, transaction failures, and governor limit exceptions.
Types of DML Limits
1. Total DML Statements
Salesforce limits the total number of DML statements per transaction. Each insert, update, delete, or undelete operation counts towards this limit.
2. DML Rows
The DML rows limit specifies the maximum number of records that can be processed in a single transaction across all DML operations.
3. DML Statements per Object
Salesforce imposes limits on the number of DML statements that can be executed per object in a single transaction.
4. DML Statements in Apex Triggers
Apex triggers have their own set of DML limits, which are separate from the limits applicable to other Apex code.
Best Practices for Managing DML Limits
- Bulkify Your Code: Use bulk processing techniques like Bulk API, batch Apex, and bulk DML operations to process records in batches and reduce the number of DML statements.
- Optimize Queries: Minimize the number of queries and optimize SOQL queries to fetch only the required data.
- Avoid Nested Loops: Refrain from using nested loops as they can lead to hitting DML limits, especially when processing large datasets.
- Handle Exceptions: Implement error handling mechanisms to handle governor limit exceptions gracefully and prevent transaction failures.
- Monitor Limits: Monitor DML usage using Salesforce Limits class and system logs to identify potential bottlenecks and optimize code accordingly.
What is the limit of DML in Process Builder?
Process Builder in Salesforce has a limit of 150 DML statements per transaction. This includes all the create, update, and delete operations executed as part of the process. It’s crucial to design your processes efficiently to stay within these limits and avoid hitting governor limit exceptions.

Frequently Asked Questions (FAQs)
1. What happens if DML limits are exceeded?
Exceeding DML limits can result in governor limit exceptions, causing transaction failures. It’s crucial to optimize code and monitor DML usage to avoid hitting these limits.
2. How can I check DML usage in Salesforce?
You can monitor DML usage using the Limits class in Apex code or by analyzing system logs to track the number of DML statements executed in a transaction.
3. Can DML limits be increased?
No, DML limits cannot be increased beyond the predefined governor limits set by Salesforce. It’s essential to optimize code and design efficient solutions to stay within these limits.
4. Are DML limits enforced in all Salesforce environments?
Yes, DML limits are enforced in all Salesforce environments, including production, sandbox, and developer orgs. It’s essential to adhere to these limits to ensure the stability and performance of your Salesforce instance.
Conclusion
Effective management of Salesforce DML limits is crucial for maintaining the stability, performance, and reliability of Salesforce implementations. By understanding the types of DML limits, implementing best practices for staying within limits, and leveraging external resources and FAQs, organizations can optimize code, prevent governor limit exceptions, and ensure a seamless user experience on the Salesforce platform.
