Hi Rob.
To see delta records of 2lis_02_itm in rsa3, let you follow steps;
1. replicate datasource and initial load with without data initialization in infopackage.
in order to generate delta queue that is showed in rsa7 on ECC.
2. after making change (Ex> change purchasing quantity by ME22 )
let you send Outbound Queue to delta Queue by executing Job in T-cobe LBWE and
3. you execute option of which extraction mode in rsa3's report screen have delta.
addtional : after making change of purchasing doc, if you want to see delta data in outbound queue ,
let you use t-code LBWQ.
