Applications and Tables

Hello

Hopefully someone experienced can help me with this, i have just started in a support role from being a user for the past 4/5 years. Is there a list of which "core" applications update which tables

i.e. i know that if i create a record in the item master the table updated will be F4101 and item branch F4102

However for some standard applications like raising a purchase order there will be both the purchasing file and the purchasing ledger (which my mind wouldnt immediately think of)

So a quick reference list or guide would be excellent

Thanks
