Hi,

We are trying to blank/null the values already present in the object/field using PATCH. For eg. I want to clear the value of Phone area code. How to pass the value to make it blank ?

 

Below JSON payload not working.

{
  "WorkPhoneCountryCode" : null,
  "WorkPhoneNumber" : "61738914302"  
}

Getting below error -

WorkPhoneCountryCode is invalid or empty.oracle.apps.fnd.applcore.messages.FndMessagesUtil$FndMapResourceBundle
