Aditional field in standard table and screen

Hi friends.

I'd like to know how to add a new field in a table and make it visible in standard transaction.

In this case, the table is EBAN and transaction is ME51N, ME52N and ME53N. This new field must be includded in transaction items grid.

I've already added field to CI... include in EBAN but this new field does't appear in standard transaction.

I've already saw variant and this new field doesn't appear there too.

Any idea ? Any SAP Note (I hadn't find any sap note yet) ?

thanks.
