I faced strange behaviour with my RichClient. I wanted to buid report which take data from Excell (xlsx) as a source and that Excell has 51777 records, diffrence records and to be sure I created ID in Excell. But when I use this Excell as a source some data are missing - about 20 records. I founf this missing records and paste it into seperate excell file and then built report one more time and all missing recorder from previous report appeared. So In my opinion it wasn't problem of incorrect data.
What is strage also that in Data tab in RichClient I see total number as 51777 so in my opinion RichClient read all records but didn't show all.
