why do we need PBO event in dialog module other than setting pf status and title bar

Hi SANDEEP,

in PBO the screen painting is done according to the screen attributes.if u want to change attributes of any filed you need to do it here.

In PBO event data is transfered to program fields to screen fields.

Hello Sandeep,

PBO module is used to carry out all steps before screen is displayed. It could be setting PF status, tiltle bar, fetching data from data base for display, conditional display/filtering data based on user input etc.

i want to display a field in screen which need to be selected from database i can write in PBO as well as in report program then whats the difference

HI VENU

PBO comes before giving input to screen so how it can be filtered depending upon user input

[Former Member]

Data fetch can be done in PAI also. it'll be better to fetch data in PAI.

but always check some condition according to your logic before u fetch data, otherwise it'll decrease program performance...

Hello Sandeep,

If there are two screens in your dialog program; the first one showing overview and the other details details, then data selection/filtering are carried out in the PBO of second screen based on input in first screen.
