Module Pool - Using Selection Screen



For select options, create sub-screen area in your screen layout where you want to create the select options. In the top include of your module pool program declare a selection screen as a sub-screen

e.g.

SELECTION-SCREEN BEGIN OF SCREEN 100 AS SUBSCREEN.
Select-options s_matnr for mara-matnr.
SELECTION-SCREEN END OF SCREEN.

 In the PBO and PAI of the main screen where the select options needs to be created do a

call subscreen of the above screen (100).

CALL SUBCREEN sub_area INCLUDING.

This call subscreen statement is necessary for transport of values between screen and program.
All validations of the selection screen fields e.g. the s_matnr field created above should be done in selection screen events like AT SELECTION-SCREEN etc. and not in PAI. These selection screen validations etc. should be done in the top include only.

Instance constructor - When we create any object and initialize , instance constructor has been used .               In other word initialization of any object we use...

Module Pool- Chain & Endchain

Chain & Endchain use for validation of field . Sometimes we want to check several fields as a group. To do this, include the fields in a FIELD statement, and enclose everything in a CHAIN-ENDCHAIN block. Example **** Screen flow logic: **** CHAIN. FIELD: SPFLI-CARRID, SPFLI-CONNID. MODULE CHECK_FLIGHT. ENDCHAIN. When an error is found inside a chain, the screen is re-displayed, and all fields found anywhere in the chain are input-enabled. All non-chain fields remain disabled.
