Send PDF with oData & Media Handling in the oData

Hello ABAPPERS,

Today’s topic is very interesting . The aim is send Adobeform pdf with oData, also we can send Smartform as well.  This is very easy thing for  implementation. I will explain details step by step.

Prerequests

-Knowledge about adobeform or smartform

-Basic knowledge about oData

-SAP Gateway usage

First of all,  We create an Adobeform and a structure for using in the odata.

Then we can create gateway service from our structure.

In the section of entity types, We must choose the our entity as ‘Media’.

Then we will go to the Data Provider class and redefine the get_stream method inside the folder ‘/IWBEP/IF_MGW_APPL_SRV_RUNTIME’

Then we will call the pdf to get RAWSTRING data. After that we give the RAWSTRING data to the ‘er_stream -value’ and give the mimetype as ‘application/pdf’ to display pdf data. Also we can send different  files as well like jpeg .

As a result we can send pdf files with oData. You can check in the SAP Gateway Client.
