Is there a standard web-service API to split open items in receivables customer account?

Hello sap community,

I am trying to find an API to execute the function of split open items on an invoice in a customer account. I have searched a lot in the service explorer but found no web service that executes this functionality. Kindly guide me if there is any standard web-service that i can use or should I try to create a custom web service using the SDK.

Thanks in advance.
