Multi-Frame Applications 

Purpose

In a multi-frame application, a subscreen is used to represent each frame in SAP system. Each subscreen has its own screen number and module pool.

Process Flow

...

       1.      Just as for single-frame applications, the Internet Transaction Server (ITS) tells a multi-frame transaction which main screen is required by sending the OK code AWSY.

       2.       If one or more of the subscreen screens need synchronizing, the ITS notifies the multi-frame application by sending the OK code AWSS. This OK code is sent only once.

       3.      In this case, your application must call the function module ITS_GET_SYNC_INFO to retrieve the requested subscreens. The returned table SYNC_INFO contains one record for every subscreen. The parameter SYNC_INFO-SUBSC contains the name of the subscreen, SYNC_INFO-REPID contains the subscreen’s module pool, and SYNC_INFO-DYNNR contains the requested screen number for the subscreen.

The following processing logic illustrates this:

PROCESS BEFORE OUTPUT.
call subscreen groups  including DYNMOD_GROUPS  dynnr_GROUPS.
call subscreen product including DYNMOD_PRODUCT dynnr_PRODUCT.
call subscreen basket  including DYNMOD_BASKET  dynnr_BASKET.

PROCESS AFTER INPUT.
MODULE PROCESS_FCODE.
Call subscreen groups.
Call subscreen product.
Call subscreen basket.
