Rest API Web service for Post request on the PRECEIPT representation.

Hello fellow community, 

I have been trying to POST records on the PRECEIPT representation but I am unable to do that. I have enabled the edit facets in the representation, checked the modification creation ,methods but still seeing no luck in using the POST request. Please if anybody can help me with this issue, I am new to Sage x3 development so in details steps would help me alot. 

Thanks. 

The YPRECEIPT is the duplicate of PRECEIPT
