Dynamic Table with validation

Hi,

I need to have a Screen that has an input field for the user to enter the table name. The code behind will need to be able to know the fieldname (column) of the table schema. It also must do a simple validation on all the data. It will return the row number and the fieldname (column) of the data if it is blank. This is a dynamic program, regardless of SAP table 'spfli' or custom table that user define. It should work well also. Is it possible to do that? How to do and what is the code like?

Best Regards,

Rayden
