Hi,

In SAP the buffers are used to store the SAP object/data from DB.When the user requests data the work process first checks the buffers for the data requsted by the user,

If there are enough buffer then it returns to the user with the data and increase the speed of the access and increases the performance. In case the dats is not found then it returns to the user with the data by increasing the speed of the access and the performance.You shoud have a better buffer size. if your buffer size is very small then the data put into the buffer will be pushed out forthe new data.

The red color indicates the no.of objects swaped out from the buffer to accomodate the new object in the buffer.

Please check the below links . Hope this helps

did you set the parameters after the pregolive check done by sap.

I think thet your profile parameters are not scheduled prperly.so schedule an early watch report and checkthe parameters.

This is wrong... SWAP should be 3 to 4 times the size of the physical memory.

Also post your current memory parameters
