Web dynpro or Integrated planning???

Hello all,

This is my first project as trainee so i need a little help. I need to create a simple web application to do as below:

1) Data Entry from local departments on a web based application- Enter / Edit / Delete data i.e. customer and product entry

2) Monthly Entry of customer and product data

3) Internal control of entry (done by other user)

4) Save the data in BW cube or datastore?????

5) Retrieve the data from BW and show it as a web report

Are BI Integrated Planning and Web dynpro right tools for this kind of application? If yes, which tool will be the best fit for this kind of requirement? And why is it the best fit?

Many thanks,

Ruud Slenders
