On an on-premise we have option to call BAPI for CRUD operations. How can we achieve the same in SAP cloud environment. For example I am trying to find solution to post FI documents from external API into SAP Cloud, equivalent to bapi_acc_document_post in on-premise.
Thanks.
In Cloud Environment you can enable SAP API Business Hub to access APIs described in api.sap.com
There are several APIs available for different SAP Applications; for example check Journal Entry - Post (Asynchronous)
You can find a Business documentation describing the use cases from a functional perspective as well as technical informations (API Specs, WSDL, urls etc..)
