You seem a little confused here.
The datasource is replicated from R/3 to BW and when assigned to an infosource becomes your transfer structure. This is the format of the data in the PSA. You then assign infoobjects to the transfer structure fields. Then you have some transfer rules which translate the transfer structure to the format of the communication structure (so the two can be different). You then link the infosource communication structure to a data target such as a cube via the update rules which can again change the format and structure of the data.
So the data in the cube can look different to the data in R/3 because of 1) the extractor may change the data! 2) the transfer structure may change the data 3) the update rules may change the data.

: I have created a communication structure for an infosource and created a cube for it. However the results I'm getting into the cube are not what I am expecting when I create the infopackage. Does the communication structure need to map exactly to the datasource on R/3 with regard to the sequence of the "fields/infoobjects"?
