Reading data from infocube

Question

Hi all,
We have an infocube which contains some figures like number of days, number of hours etc. We should calculate some indicators on them, something like:
Ind = Hours1 * 100 / Hours1 + Hours2
where Hours1 and Hours2 are figures which come from two different records, with codes 1 and 2.
We are not using BEx, but some other reporting tool which takes quite a long time over it. So we were asked to write an ABAP program which should read the data out of the InfoCube and calculate these indicators on basis of such fomulas.  Writing a Transfer Rule with the InfoCube as DataSource proved not to be such a good idea because data is split in packages for the upload, so a subroutine within the transfer rule might not be able to find the records with codes 1 and 2 within the same package and that gives errors.
The question is: does anyone know of programs/functions/classes which could do the job? so read data from the infocube and eventually update it back into the infocube after the calculations?
Thanks in advance,
Ioana

Hi Ioana,
maybe Analysis Process Designer (APD) can solve your problem. In an APD process you can read the data from any InfoProvider, calculate your key figures in an ABAP routine and write the result to an ODS. This ODS has to be transactional and can't be directly reported, but you can report the ODS data by defining an InfoSet on it; you can also write the ODS data to any cube via the data mart interface. The data package split shouldn't be a problem in the APD process because you can define a partitioning characteristic in the APD routine.
The APD is available in BW 3.x via transaction RSANWB.
