Answer 1

Try doing something like this
DATA : v_netwr             TYPE vbak-netwr,
            v_netwr1           TYPE vbak-netwr,
            v_netwr_c_1(21) TYPE c            ,
            v_netwr_c_2(21) TYPE c            .
Assigning a value to v_netwr. You will probably do this using a select statement
v_netwr = 10.
Assign to a character field of the same length. Numerical values cannot be *passed
v_netwr_c_1 = v_netwr.
Pass the value to SAP memory
SET PARAMETER ID 'ZNETWR' FIELD v_netwr_c_1.
Get the value back from SAP memory. I assume this statement is in another user-exit. The field in which you import should also be a character field
GET PARAMETER ID 'ZNETWR' FIELD v_netwr_c_2.
Assign the data from the character variable to the numeric variable
v_netwr1 = v_netwr_c_2.
This statement is used only for testing this logic. It will not form part of your code
WRITE:/  v_netwr1.
Let me know if this helped you.
