One element influencing the performance of a BEx Workbook is its size. Each time you open a BEX Workbook from your BEx Analyzer, the excel file corresponding to the BEx Workbook is retrieved from the BW servers (it is stored as blob format in table RSRWBSTORE) and transferred to the front end.

Thus, before even doing a first refresh, there might be a perceivable delay due to the workbook transfer.

You can monitor the sizes of all the workbooks in your BW system with the following report available in Saplink format:

Download – PROG_ZBI_WORKBOOK_SIZES.slnk –  2.4 kB – 329   downloads

The size displayed by the report is in lines in table RSRBWSTORE. The real size is about 2000kb multiplied by the number of lines.

(Note: The BEx Workbooks are also stored in temp directory on the PC when executed. I do not know however if this means that the entire workbook is not always transferred on opening. If you have any info on the subject, please leave a comment.)

The below code also displays the French and Dutch workbook title.  (Just change the F and N to E and D to have it in English and German for instance.
