Nexel when transitioning to Web Capsules
Hi, I'm having an issue with existing Nexel layouts transitioning capsules from Client to Web (now on Board 10.7) - every time the procedure is ran (which includes 'Save data entry' step) Nexel doesn't save to the cube anymore (it only contains the values we prepopulate the cube with to give us a base). My current work…

Level 200 Module 207: Build a Data Model and Capsule Procedure to increase the CY budget by 5%
I might have missed it, but I think the instructions are missing the part where you should multiply py actual * 1.05 to get current year budget with 5% increase. In Level 200 207 shouldn't this have Set Expression to a*1.05? In the "MAIN" group, create a "Data flow" step, in "CONFIGURE LAYOUT" use "ACT - DF - Sales LC" as…

Procedure - DataFlow - Algorithm of dataflow (c=a*b) should show the headings of source blocks
When editing the blocks of a DataFlow LayOut, it's possible to set headings to each blocks. When saving the DataFlow, the heading of the target is displayed in the algorithm / detail, but not the heading of the sources. It could be usefull to have the headings set in LayOut for sources as well.

Copy of BLOB Cubes in DataFlows
Hi All, at the moment it is not possible to copy blob Cubes in dataflows. It would be great when a simple copy of BLOB Cubes in DataFlow would be possible. It also would be great if the target BLOB Cube could have some more or leass dimensions than the source BLOB Cube. Regards, FabFro

Make visible "by row" and "show all" option in Dataflow
As you might have noticed, dataflow behave differently if you create the layout directly or you copy it from and existing report having sometihing by row and flag show all set. Would be nice to have it visible directly in dataflow configuration instead of setting/viewing it only when you copy and paste back to a report. I…

Culture-sensitivity with @datetime in Smart Import
Hi, I have a bit of trouble with culture and the formula @datetime. I have a cube that is populated 2 ways: either the user uses a smart import object to fill other cubes, and then the datetime information arrives into this timestamp cube using a formula. Or, if the users don't want to input anything, they can click a…

Dataflows : c=a*b versus c=join(a*b)
Hi everyone, I see in an application developed by consultants here, that some dataflows are using a c=join(a*b) formula, and I can't find the difference with "c=a*b" when I test on my dataflows. In some cases, "JOIN" appears in the db log as the algorithm, and some other time it's HBMP. Does anyone knows what is the…

Save data in ROLAP cube with DataFlow
I get the concept of data being stored in the DBMS vs database through rolap cubes. I have a dense cube linked and the table exist (can we override the default table name with something that is more meaning full to our organization?). Then I define a dataview with this cube and enable data entry. The list of ALL entity…

What is Open Sparsity?
I've seen a few cases now where checking the Open Sparsity option on a dataflow does the trick to ensure data makes it to the destination cube correctly. I was hoping someone could help articulate when and why this should be used, or avoided? As I understand it, the opensparsity option removes any assumptions about where…
