Data mapping limitations

There are some limitations when you are mapping JSON properties to REST response and request properties. The Data Type wizard displays an error message when a mapping is invalid.

• If properties are in different nesting levels, they must be mapped to the same nesting level, for example, if a property on the left is in a sub-object, you cannot map it to a top-level property on the right. You can only map it to a second-level nested property.
• Scaler properties must be mapped to scaler properties.
• List properties must be mapped to list properties.
• You cannot map two properties to the same property. If you try to do it, the last property mapped is used.
• There are some limitations on types of properties that can be mapped to one another, for example, you cannot map a string to an integer.
• The only supported date format is the Pega date format.
