Min, Max Block Size, Default Blocksize ??

[Former Member]

Hi All,

Can any one please explain me the exact meaning of the Min Block size, Max Blocksize that we maintain under the "Block size for DP/SNP Parallel Processing Profile ".

Please let me know the application of the same. Why do we maintain this setting ???

What does it mean by a BLOCK SIZE ???

Any input on the same is highly appreciated.

Thanks in Advance,

Prasad.

Hi Prasad,

Block Size is the number of parallel processes that are being executed in background during the application. This is normally a configuration activity to be configured in line with basis.

In Block size, we enter the number of objects to be processed per block by the CIF comparison/reconciliation during data selection in SAP APO or in the partner system.

If you increase the block size, the memory required also increases. This has a positive effect on performance. If processes are cancelled due to lack of memory, you can decrease the block size to save memory.

If you do not enter anything here, the system determines the block size dynamically from the number of objects that actually exist and the maximum number of work processes available.

Normally, when you execute a job in background, it picks up the application server automatically or by manually defined server. In parallel processing, at a time, one or more job of the same identify can be triggered under this scenario by defining application servers. But too many parallel processing activity will affect the performance.

One needs to define the parallel processes also to control system behaviour. The Parallel processing profile is defined for parallel processing of background jobs. You then assign these profiles to variants in the applications.
