we are trying to extract data from SAP to external system with using standard RFM .
The following are details that we are trying now.
1) from other server, call RFC to send the request for retrieving the data remotely from ERP server via VPN
2) store the extracted data into a specific folder which is located in the same environment with ERP server .
3) get the data we want from a specific folder to STFP server.
4)currently not going to specify which data is extracted. it means from UI user can just set the table value to fetch the data remotely from SAP
Those are totally that we want to do. But we just encountered some issues
1) can not store the extracted data into a specific folder . so is there any workaround that we can fix resolve it to save data ? btw, we can not change any configuration or extension inside of SAP. so we have to think the workaround in RFC caller side.
2)RFC limitation that we used. As far as you know, RFC_READ_TABLE has some restrictions, like limitation of 512 bites for 1 record, or the number of data extraction have under 100GB. So is there any workaround that we can try or any RFC that you can Recommend?
