Conflict - DI API Object Ref Help file and SDK

Dear Experts,

Recently we tried to cancel Journal Entry object via DI API and before that we referred B1 DI API - Object reference html help file. It is mentioned that the method 'Cancel' & 'Close' are not supported for the object Journal Entry.

But we successfully 'Cancelled' the Journal Entry using DI API in our Add-on which seems to be a conflict with DI API help file and the SDK.

Please advice.

Thanks.

Hari
