In the PAI of the screen 100 write the following thing. suppose wf_var is the field whose value u want to access in screen 200
constants :co_field1(13) type c 'MI_field1_100'.
The value of the constant shud be unique.
EXPORT wf_var TO DATABASE indx(st) ID co_field1.
make sure that co_field1 is not used previously and it is unique.
then in the PBO of screen 200.
declare the same field of the same type and use
IMPORT wf_var from DATABASE indx(st) ID co_field1.
then wf_var will contain the value that was thr in screen 100
Hope it is clear to you.
