To send/receive images to SAP Gateway, you can follow these steps:
Define a binary field in your SAP Gateway Service Entity: You can define a binary field in your Service Entity using the ABAP Dictionary. This field will store the binary data of the image.
Upload an image to SAP Gateway Service Entity: To upload an image, you need to convert the image to binary format and then pass the binary data to the binary field of the Service Entity. You can use ABAP functions like SCMS_BINARY_TO_XSTRING to convert an image to binary format.
Create a media link entry for the image: A media link entry is created to store metadata of the uploaded image. This metadata includes the URL to access the binary data of the image.
Define a media type: Define a media type that represents the image. You can use standard media types like image/png or image/jpeg.
Enable media handling in your SAP Gateway Service: You need to enable media handling in your SAP Gateway Service by configuring the service to handle media types.
Retrieve an image from SAP Gateway Service Entity: To retrieve an image, you can call the Service Entity and retrieve the binary data of the image. You can then convert the binary data to an image format like PNG or JPEG and display it in your application.
Overall, the process involves defining a binary field to store the image data, uploading the image in binary format to the Service Entity, creating a media link entry for the image, defining a media type, enabling media handling in the SAP Gateway Service, and finally retrieving the image data from the Service Entity and converting it to an image format for display.
