loop at screen - not all fields are available

[Former Member]

Hi all,

I want to set some fields on the screen invisible.

When I do the loop at screen in PBO not all fields from the screen are available.

Just four fields are available. In the screen there are about 20 fields.

I try to use the chain. field xyz. endchain... But it was not the problem.

Any ideas?

regards

Loop at screen.

when screen-name eq field1.

screen-invisible = 1.

.... and so on

endloop.

you can check the value of structure SCREEN in debugging . This will help what is going inside your code.
