SAPLSBAL_DB - Application Log: Database Interface

Overview of the most important Application Log function groups

• SBAL
  Collects messages.
  You open a log, e.g. with BAL_LOG_CREATE and put messages in it with BAL_LOG_MSG_ADD.

• SBAL_DISPLAY
  Displays logs. The most important module is BAL_DSP_LOG_DISPLAY which displays logs in full screen.
  The function modules which begin with BAL_DSP_OUTPUT_... output logs in a subscreen.

• SBAL_CNTL
  Display log in Control container.
  BAL_CNTL_CREATE creates the control, BAL_CNTL_REFRESH displays a new dataset in this control and BAL_CNTL_FREE deletes this control.

• SBAL_PROFILE
  The separation of data and presentation is an important principle in the display modules in function groups SABL_DISPLAY and SBAL_CNTL: you can specify the data format in display profiles.
  The function group SBAL_PROFILE contains various display profiles, or you can create your own.
  For example, BAL_DSP_PROFILE_POPUP_GET contains a display profile which displays a log in a popup.

• SBAL_DB
  Application Log database interface.
  You can save logs in the database with BAL_DB_SAVE, BAL_DB_SEARCH searches for logs and BAL_DB_LOAD loads them into main memory.

• SBAL_TOOLBOX
  Rarely-used modules for special scenarios.
  BAL_DB_ENQUEUE locks an existing log which can then be loaded into main memory and changed (e.g. with BAL_LOG_HDR_CHANGE and BAL_LOG_MSG_CHANGE.
