Hi Kesavadas,

Is there any way to increase the performance other than these methods.

Thanks & Regards ,

You could try the following:

- regroup all excels to be downloaded into one zip file.

There are a few classes to do this (CL_ABAP_ZIP, CL_ABAP_GZIP) but needs to be tried out. It is just an idea, I have never tried this.

You can download once a zip file containing all the excel files.

You will be downloading one a bigger file once. Difficult to say right now if the gain in performance will be positive...

Hi Seshadri ,

There is no difference in these two options which you have provided.

The only thing which u can do is try that ZIP class as stated by Phillip for downloading at once and the unzip it after download...

Performance will also be good by using this.

Hope this will help.....

Hi,

Say for example u have the scenario to download the 3 itab.

Write a perform and use that in the 3 place..

1.build the file name before using the perform

Perform download tables it_tab1 using p_file.

Perform download tables it_tab2 using p_file.

Perform download tables it_tab3 using p_file.

even we can pass the different parameters..
