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.

This graphic is explained in the accompanying text.

Process

  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:
