How to write a Report for Debtors Aging Report (FI)?

Hi all,

I am anticipating to write some abap reports..Here is one of them..Anyone can help me with writing a Report , how to do 'Debtors Aging Report (FI)' ..

But since I am new to Abap , if you wish to reply, please use a little more detail and simple explanation, step by step so I can understand what is the idea, how it can be acheived...what kind of report should be used , abap techniques, tables, the structure of the program etc. things that probably look natural to expert-abaper...:)

Appreciate your help!
