I just need to know where the Synchronization Table (which controls the app servers' buffer synchronization) is present ?

    Hi Prasad,

    there is one central table (DDLOG), in which timestamp of last change is written.

    Application servers read in distinct intervals (1 - 2 minutes, depending on system parameter), if changes in buffered tables occurred. If yes, local buffer (off this table) is set invalid, otherwise buffer is still valid.

    Before you try to implement your own buffer synchronization, deactivate buffer for your table of interest. Already SAP states in extended help for buffer settings, only activate buffering if you have very rare write access or if temporary inconsistencies are acceptable.

      Hello Prasad,

      I suppose you could also have a look at the table DDSYN. This table contains <i>Parameters for Buffer Synchronization</i>.

      If you are further interested, I suggest that you examine the elements of the Package <b>SBUF</b> in the Object Navigator (SE80).
