It happens quite often, source data comes from a single infotype, but users want informations coming from different subtypes moved to different infoobjects on the same row (i.e. one row per employee per time period), this usually requires some ABAP but there is a trick.
You can use infosets to differentiate logically between rows of the infotype, see below:
It's like having the ability to run different transformations from the same source to the same target according to different values of one column.
Something like inverted rule groups, which are great at turning data in a long row into data in different columns:
An example of rule group usage:
PERNR LGA01 BET01 LGA02 BET02 etc
PERNR LGA01 BET01
PERNR LGA02 BET02
which can fit nicely into an infocube.
