Question:
i got the below from my system log
"Tcod MNo Text
ME21 BB8 Buffer overflow loading table A017"
clicking on it brings me to the below documentation
"The free space in the table buffer is not sufficient to load the table.
The table should either not be buffered, or the table buffer area
should be increased in the profile
(zcsa/table_buffer_area for the 100% table buffer or
rtbb/buffer_length for the partial table buffer)."
my questions are
1) this table buffer is the same as the sap application buffer which contains data requested by sap from oracle?
2) buffer overflow is dependent on the size of the buffer as well. we can increase the size of the buffer but
surely there is a guideline to how much we can increase since increasing it will meant a decrease of other stuff?
Answer:
Refer to OSS Note 480710 - Maximum size of table buffers and OSS Note 91335 - ME21 performance with condition tables A017 & A018 which talks about A017 being too big to buffer.
