Hi Daniel,
You can use all 233 key figures in infocube , as like below.
Create one customer infoobject which holds type of key figure value
Example
ZTYPE - char 60 length and 0AMOUNT one
ZTYPE 0AMOUNT
CAMT -- Credit amount 200$
DAMT -- Debit amount 120$
BAMT -- Balance amount 80$
summary is group similar key figure values and update in ONE key figure by differentiating TYPE of values, by doing this 233 key figures may come down 120 key figures this just example, its again based on grouping.
Thank you,
Nanda
