The table buffer is located between the application and the
database. Its goal is to cache portions of a database table
in the application server to reduce database load and
network communication.

ST10 will help you to identify buffering problems.
or use SE13 to display the buffer settings for several tables.

We can activate buffering for a table in the ABAP Dictionary
using Technical settings in transaction SE11 or SE13, you
can choose between different settings like Fully buffered,
Generic area buffered, and single record buffered.

Table buffer advantages:
Makes data access many time faster
Reduces the load on the database
Reduces the load on the network and on CPU
The work process is freed more quickly for other work

Table buffer disadvantages:
If an SAP system consists of more than one SAP instance,
then buffering might be dangerous.

Invalidation of buffered data - If data stored in a buffer
is outdated compared to data on the database, then this data
is no longer available for access and will be overwritten.

By setting the system parameter rdisp/bufrefmode to the
value sendon, exeauto you can ensure the following mechanism
and is strongly recommended by SAP:

The sendon switch for the parameter rdisp/bufrefmode will
force the SAP system to log each change to buffered data in
the table DDLOG on the database. By setting the exeauto
switch for the same parameter, you can force all SAP
instance to periodically check the validity of their locally
buffered data against table DDLOG

I have a requirement from the SD people wherein whenver one runs the tcode F-02 (Enter G/L account Policy : Header Data), they should not get the list of all acounts in the ACCOUNT field. But when i go to pfcg to check for restricting the list, i dont find any pertinet auth field for doing so. Isi t something that we can ( as Basis Admin) do or the ABAPpers to do. Maybe the ABAPpers have to program the screen where in they need to restrict the list options. If not so, lemme know the auth field that has to bet set if any.
