Lumira Scheduling for BW

Former Member

Hello all,

I have some questions around scheduling for Lumira on BW, maybe someone is able to help me:

1) if I schedule the Lumira document to refresh the data set every night, what happens during the refresh with the current data set? is the user still able to work with the Lumira document? just thought that the refresh maybe takes more than 20 minutes.

2) does anyone have experience  how big the data set can be? is 1.000.000.000 cells to much?

3) does the data set also include the BW authorization? If a user with BW authorization only on customer B, does he see the data of customer C in the data set?

Thanks for your help

Thorsten

In a nutshell, Lumira works the same way as Crystal Reports and WEBI. E.g.; for #1, the scheduled instance would be in history. For #3, on refresh you'd only see the data you are supposed to see.

As for #2, this will depend on all kinds of variables. I have seen docs with 10 million cells. But probably the best way to approach this is by having a look at the doc,

Also, the following SAP Note will be good to consider:

(Pretty well all recommendations in the above will apply to Lumira (as well as CR and WEBI))

Ludek, are you sure about #3?

Because this in my experience was a big issue in Webi: when you schedule the report to run at night the instance had ALL data in there. If a user (through SAP authentication on the BW system) then connected to the BI launchpad he was able to see all data. It was only when he refreshed the document that the BW authorizations would be leveraged.

Not saying this was a bug, because it's very logical that it works in this way.

That's why i'm wondering how Lumira would be able to hande this? Won't it follow the same prinicple as webi?

thanks for your answer!

have you ever seen 1 billion cells in one data set??

That is most likely because the dataset was saved with the Lumira file. E.g.; much along the lines of Crystal Reports with the option "Saved Data" enabled. Only on refresh would you get the correct data(?).

Umm - no. What would you do with a billion cells? That would make sense in a product like Lumira anyhow.
