SAP_IsIgnoreProperties property use in SAP CPI/ SAP HCI

Tried lot in google about this property, but I couldn't find the usage of this below property used in the script. If anyone has idea can update in below comments will be useful for other too.

Soon I will try to find and update it.

Groovy Script:

import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;

def Message processData(Message message) {
//Set header SAP_IsIgnoreProperties
message.setHeader("SAP_IsIgnoreProperties",new Boolean(true));

return message;
}
