And get used to the following :
* SAP will try its darndest to keep you out of the database except through
their tools (such as sapdba) which introduce interesting new bugs
* In our instance : 21303 tables; foreign key constraints : 0 (yep, zero)
* SAP keeps track of its objects in its own data dictionary. Of course,
the mapping between what SAP says is a table and what Oracle says is a
table is NOT 1-to-1.
* Things you think are numbers, dates, ... are almost always stored in
varchar columns
etc.etc.etc...

No problemo, dirt easy: just use your normal sizing rules
for any aspect of the Oracle database using any other
product, multiply by at least 1000 and you may start getting
into the ballpark of the enormous waste of space that
product is. From there, it's all up-hill.
Be warned: due to the ginormous cost of the blessed thing,
your company may look into outsourcing your job to reduce
the TCO. A term that when dealing with SAP always makes
me laugh.
Merry Christmas.
