Buffer Area

In the documentation of function module EXIT_/SAPAPO/SAPLATPQ_010 there is the following statement:

"The function module can be used to initialize the data in the user exit function group. To be able to work with the following user exits, the module can save the call parameters in a buffer area."

What is the buffer area?

How should I access that values from other function modules that belongs to the function group?

Thanks in advance!

    The buffer area is the temporary storage area you would have defined for capturing the application logs. The log data are initially collected in local memory, and are then written to the database. This procedure speeds up processing and reduces the number of database accesses. It is also possible to write log data to the database individually, to avoid losing the log records collected up to that point in the event of termination of the application.The logged data can be read in the database and displayed on the screen. It is also possible to read and to display the log data which is buffered in local memory with a log number.

    you can capture the detailed information, either for the whole log or for each individual log msg in two ways:

    - Text module with any number of parameters

    - User exit with any number of parameters

    When the log is analyzed either the text module with the specified parameters is displayed, or the user exit is performed, on request. Additional information can be saved in an INDX-type table, which is used by the user exit analysis.

    In this way it is possible, for example, to save lists which can be displayed when the log is analyzed, with the help of the user exit and will ensure that you are not using values for other users.

    hope that clarifies.
