Export to shared buffer performance Implications

[former_member194669]

All,

I am using the following statement in one of the programs to export an internal table

EXPORT it_dtab TO SHARED BUFFER indx(st) ID 'ZMME'.

I like to know what the performance implications by using this ?

Hi,

Unless your internal table is too huge (May be millions of records) it is fine.

Thanks,

Vinod,

I have internal table max of 50000 records and ( Internal table only 7 fields ) , But i am lloking some kind of link or documentation that it will not affect performance.

I have search lot to find exact info that it will not affect performance

Hi,

If the records are 50K then you don't have to think much about it. You can do the performance test by debugging the EXPORT and IMPORT statements. I don't think it takes more than a second.

Did you search in help.sap.com where you can find the proof?

Thanks,

Vinod.

Vinod,

The link provided not specifiying anything about export to shared buffer.

Helo,

You could check the current memory limit set for SAP shared space @ transaction RZ11 .

Pass the profile parameter as rsdb/obj/buffersize and check the field 'Current Value' .

You could discuss with your Basis counterpart if there's a need to increase the shared memory space which

is generally not favourable as performance of other sap applns can come down on doing so.
