CRUD operation on ADP on save to reflect in BO

Summary:

I have an ADP which has to be inserted in a BO based on ATP table(Custom VBCS BO). The ADP has some columns which is there in specified BO as well (ADP in not based on BO type but the names of the attributes are same). The BO should get populated with the provided data and rest of the fields of the BO should be populated as null on click of save button.

Current design :

Using forEach operation on my ADP and calling the Rest endpoint for the ATP BO (operation: post) and passing the current record to the body of the REST call.
