File Attachments Approach in Gateway

1918 Views

Hi All,

We have got one requirement in Gateway. We are builiding some FI document creation application using GW and HTML UI 5 as a frontend. User has to upload the files into SAP while creating FI document. So we have to get the binary data from the frontend ( which is any format file like .xls, pdf, .txt etc) and archive that into content server. I have done some POC and got few questions & thought of discussing with all of you for better design & solution.

1. As of now, i have implemented the create_deep_insert method to get the header and line item details & this method is working fine and implemented update_stream to get the binary data from the front end.

Question :Would it be possible to take the normal data & binary data in the single service call. That means, when user enters the Finance document header data, line item data and upload file at front end, then would it possible to send all these in the single service call.

Because, as per the business process, user has to attach the document and then create the FI document. But in our normal SAP process, i have to create the FI document first in SAP and then archive the file by linking the fi document which was created.

So issue here is, Front end application has to wait till i return the create_deep_insert response back to them & then they have to call the attachement collection to update the file. So is there any way to club normal data and binary data in the same entity.

2. After implementation of the Update_stream ( im using this as i have to take some key fields, which is not happening in create_stream method ) , i have tested from the /iwfnd/gw_client by clicking on ADD FILE button. It is working as expected and file got archieved. But how to get the payload xml file to pass this binary stream.

If i give xml file like attached .txt, it is taking that whole XML as a stream rather than value tab data.

 

3. Would it be possible to upload more than 1 file in the single service call from the front end application?

I really appreciate your thoughts, solutions, messages on this topic & i have searched the SCN before posing this message for same kind of messages.

Thanks and Regards,

Naveen Veshala
