Media Handling in SAP ABAP On-Premise Using RAP model

[former_member661755]

For Media Handling in ABAP Programming model for Fiori, we can implement CREATE_STREAM, GET_STREAM in code based implementation of the DPC_EXT class. What is the equivalent approach in RAP?

The requirement is to update data from csv or json file into database tables in on-premise system using RAP model.

It is purely on-premise no cloud involved.

Hi volker.drees ,

Is this workaround still valid, or there is a way using RAP to upload data from an Excel file (xlsx) into a responsive table within an object page section (using Fiori Elements).

I've seen standard Fiori apps on S4H 2020 doing so, so just asking if any improvements in this matter have been made?

I haven't found info about it in the documentation for RAP/Fiori extenions.

Thanks and best regards,

Laura

Hello Laura,

from a RAP perspective the stream end-2-end support is unfortunately still not available.

I can't speak for local UI handling of Excel files, but sending any binary content to the backend should be possible with the mentioned workaround.

Hello Naveen,

it's certainly just a workaround, but you would use the string field just as a transport container.

Hello Volker,

is it possible to add string fields (or long character fields) to CDS Views/CDS View Entities?

Isn't there a restriction that fields longer than 250 characters are not allowed in CDS Entities?

Hello Naveen,

native stream support in RAP is planned, but not yet available. As an alternative you can put your file into a string / blob field. This at least allows you to transport the file using the OData channel.

Hi Volker,

In that case in order to update data from csv file, the current approach should be to convert csv into string format from front end and store in back end?

Hello,

end-2-end support for handling large objects has been released yesterday in the cloud (2208). See https://help.sap.com/docs/BTP/923180ddb98240829d935862025004d6/10a3eb645b83413cbbebe4fc1d879a62.html...

Dear Volker,

It looks there are many limitations. I have mentioned few in the blog post .
