Input Screen – Selection screen
1. The module pool program execution sequence is PBO -> Getting the input from user -> PAI -> PBO
2. For sub screen we have to specify as the sub screen in the attribute of sub screen
3. Sub screen can not have the OK_CODE4. For list box we need to select as list box in the drop down option of the
filed attribute5. We have to call the sub screen in the main screen of both PBO and PAI6. We need to loop the internal table which belongs to table control in the
PBO as well as in the PAI of the particular screen 7. A function code can be assigned to list box also so that it will trigger when
we select the value from that (ie As we have used in this program)8. We can assign value for the particular list box from fixed range value of
particular domain or using VRM_SET_VALUES in PBO and VRM_GET_VALUES in PAI
9. If we use VRM function then we need to declare TYPE-POOLS : VRM in the program
10. We can validate the sub screen in the PAI of main screen by checking the ok_code since we can’t have the ok_code in the sub screen
11. To place ICON and Check box we need to declare the fields in the internal table which we are referring in the table control so that it will display.
12. When we add new lines we need to increase the table control current line by 1 TABL_CTRL-CURRENT_LINE = TABL_CTRL-CURRENT_LINE1 + 1 in PAI
13. In the same way when we delete line from table control we need to decrease by 1 in PAI.
14. Cursor position can only be set in PBO module not in PAI.Output Screen – For multi record table control
