You need to define DATA statements in a global area, in the TOP include is a great place. The names of these variables must be exactly the same as the names of the fields in the screen. Not the labels of the fields.

Hi,

In your main program, declare three variables which you want to use on the screen

While designing the screen, in the screen painter, use the same fields for your calculations.

In the module use the variables for calculation purpose. Label is never used for any calculation as it is only an output field and cannot accept any values.

Hope this answered you question

Enjoy SAP

<i>if v assign that field is that global</i>

No, what makes it global is the fact that it is defined in the TOP include of the main program and not inside of a module.

The link between the fields in the ABAP program and the screen is just the name of the field. So if the name in your data statement is ....

data: P_PARM1 type c.

.... the the name of your screen field should be P_PARM1. That's it, the rest is handled magically by the ABAP runtime, you do not have to manage the passing of the value back and forth to/from the screen.

You mentioned that you don't see any value in the field, you do have to put a value in it before the screen is thrown. You can do this in the PBO of the screen.

P_PARM1 = 'X'.
