How to Clear One-to-Many Data

If you have One-to-Many Data stored that you don't need anymore, you may want to clear it. There are a number of ways to do this. Choose whichever suits your use case best. You can:

• Clear all One-to-Many Data for a Single Recipient
• Clear a Specific One-to-Many Tables for a Single Recipient
• Clear All One-to-Many Data for a Target Group
• Clear specific One-to-Many Tables for a Target Group

When you clear One-to-Many Data for a recipient or Target Group, the One-to-Many Table itself and its fields are not deleted. Only the values within the fields are deleted.
