I have 3 data sources coming from ecc i.e 2lis_11_vahdr,(vbeln is key field)
2lis_11_vaitm,(vbeln,posnr are key fields)
2lis_11_vakon (vbeln,posnr,kschl are key fields)
where i am loading this data to dso .
Now i want to see all the data coming from 3 datasources in a single report.
I have created infoset .but i heard infoset will have very poor performance.
Is there any other best possible way?
