You can design a process flow in Adeptia to send data of any format from your end to the SAP server by transforming it to the IDoc file using Adeptia Data mapper.
To know more about process flows, please refer to the Working with Process Flow section of the Developers Guide.
Alternatively, you may send or receive IDocs Using Data interface method. With this method you don't need to create a new process flow, you can simply use the Default_Data_Interfaces process flow.
Refer to the Using Data Interface. section of the Developers Guide for details.
