Virtual Cube with DTP for direct access

Hello experts, I would like to hear about some tips to improve performance on reporting over this kind of infoprovider. If there were no performance impact in reporting then this cubes would be perfect to face the requirement we are facing. So I would like to get some help on deciding if we can go ahead with this idea or not.
The volume of information is not going to be small in underlying cube staged in APO source system but we can take care on reports using restrictions and small horizons of information. There is no processing in BW side, we would just transfer records from source system to report.
What else besides restrictions in reports can we do to reduce query performance impact? Any work in underlying cube like partitioning, compression or so?.
Any advice from your experience?.
Thanks so much.

Hi Martin,
There are 2 BCS documents that might give you some starting point on Virtual cubes, if you have a S-userID for service.sap.com/support, these generally discuss the use of Multiproviders, helped by VirtualProviders so you'll have to skip through some redundnat content.

Virtual Cube with Services - Debugging

I want to debug the function module assigned to a Virtual Cube with services. Using transaction RSRT, I can access the FM using debugger when the query is initially called, by selecting Debug options/Default Breakpoints/VirtualCube. I want to debug subsequent navigation steps on the query. How do I access the debugger for subsequent navigation steps?

Hi Maverick,
You can extract the attributes of the characterstic but u need to configure depending on the function module you are using to read the data from basic infocubes.
I suppose in your FM u are using RSDRI_INFOPROV_READ*(check in your FM to find this) in to get the data from basic infocube. If it is the case then u need to configure interface parameter I_TH_SFC and I_T_RANGE to get the attributes. Hope it helps and if need more let me know the same. If you are using the other function modules you can follow the same logic.

Ramana

Difference between standard dtp and direct access dtp

Hi,
Can anybody tell me the difference between standard DTP and Direct access DTP other than Help.sap.com.
Regards,
Devi

simple words.. Standard DTP needs to use for Physical data targets loading.
Direct Access DTP needs to use for virtual providers. you won't pull data into BI. it will directly retrive from DS while reporting .

What is the use of Data packet dim with Virtual cube with services

Hi Friends,
Could anybody tell me what is the use of Packet dimension in Virtual cube with services , It cannot contain data persistently ,Just fetch at runtime,Then there is no Physical load happening,Then why it should be automatically created for this??
Message was edited by: Pradeep choudhari

Hi Maik,
Unit dimension will not be created automatically until and unless you have keyfigure referning units..
But my question is : Why should we have data pack dimension , which is useless in this case of Virtual cube with services.It should not be created automatically!! What do you say??

How to load data from a virtual cube with services

Hello all,
we have set up a virtual cube with service and create a BEx report to get the data from an external database. That works fine. The question is now:
Is it some how possible to "load" the data from this virtual cube with service (I know that there are not really data...) into an other InfoCube?
If that is possible, can you please give my some guidance how to set up this scenario.
Thanks in advance
Jürgen

Hi:
I don't have system before me, so try this.
I know it works for Remote Cube.
Right Click on the Cube and Select Generate Export Data Source.
If you can do this successfully, then go to Source Systems tab and select the BW. Here, Right CLick on select Replicate DataSources.
Next, go to InfoSOurces, click on Refresh. Copy the name of Virtual Cube and add 8 as a prefix and search for the infosource.
If you can see it, that means, you can load data from this cube to anywhere you want, just like you do to ODS.
ELSE.
Try and see if you can create an InfoSpoke in Virtual Cube. Tran - RSBO.
Here, you can load to a database table and then, from this table, you can create datasource, etc.
ELSE.
Create query and save it as CSV file and load it anywhere you want. This is more difficult.
Good luck

Error after transport of Virtual Cube with Services

Hi All,
would any body can suggest me how we can change the source system assignment in QA or Production client for virtual Cube with Services.
A virtual cube is created with Services using the settings for RFC and using the logical source system. however after transporting the same to the QA system the Logical Source System has not changed and thus it is giving error " Error occured while determining target system for the logical system" would any body can suggest me how i can change the logical source system assignment in QA system for Virtual Cube with services.
Points would be rewarded appropriately.
Cheers

Hi Noor,
Check this link, it may help you.

How to Virtual cube with services works

Hi,
How to Virtual cube with services works.
can anyone provide me a realtime scenerio.
if possible provide some code.
Thanks,
cheta.

For which functinality you are trying to create VC with services.
This is mostly used in SEM BCS.
You have to create cube similar path like normal cube, but select in the properties virtual cube, services.
There is a standard FM which connects the Virtual cube to the required cube in BCS. ( this is done by BCS data basis generation function) and we have to do nothing for FM.
In BCS we use virtual cube only for reporting purpose, since standard BCS cube cannot be used for reporting. hence what we do is create another virtucal cube very smiliar to BCS cube.
Then both the Virtual cube and BCS cube are connected by standard FM.

Virtual cube with services read from Multicube?

Hello All.
We have logically partitioned the Balance Sheet cube 0FIGL_C01 into 3 new cubes. Now I found that I also had to partition the Virtual cube 0FIGL_VC1 into 3 new virtual cubes( I have copied the standard function module to change the data origin).
Then I have included 4 virtual cubes in one single multicube.
When I run a query on the multicube, I get a short Dump.
My questions are:
1.- has anyone done the same logical partioning for balance sheet before?
2.- Is it possible to use a multicube as source of data for a Virtual cube with services, using the balance sheet virtual cube function module?
Thank you all for your help.
Regards,
Alfonso.

a basic cube can only be a source of data for virtual cube or for a multicube.
all cubes should have atleast one char common when u add them in a multicube.

Virtual cube with services

Hi guys,
Simple questoin!!
Where do you write the function module - in R/3 or Bw system for virtual cube with services.

Depending on where you are extracting the data from, you would host your FM in the same client.
If the source system is Non BW system, do not forget to enable the RFC indicator on the FM. When you define your Virtual Cube in BW, you will be prompted for the Source System Id and then you can link it up with the FM in the external system.
Hope it helps.

Query ID in Virtual Cube with services-Function module

Hi,
I am using virtual cube with services linked to a function module.
The function module has fixed parameters(such as infoprovider name). None of these parameters consists of query information such as query ID OR queryname .
Do any one know how to determine query which was executed this function module?
Best Regards,
Anil

Hi Claudio,
I never implemented Virtual InfoCube with services with a FM, but I know there is a couple of How To Documents about named:
- How to Reporting from External Data via Virtual InfoProvider
-How to Implement a Virtual InfoCube with Services
both with some code samples: did you read it?
Hope it helps

Report issue on Virtual cube with services

Hi,
I'm following a how-to document to report on a virtual cube using a custom function module and everything seems to be OK except it is dumping at the following line which is included in the How To document "How Tou2026Implement a virtual InfoProvider with Services".
Both <l_s_data> and E_T_DATA are of same data types as discussed in the how-to document.
append <l_s_data> to E_T_DATA
These are the declarations which are same as HowTo document
E_T_DATA TYPE STANDARD TABLE
FIELD-SYMBOLS: <l_s_data> TYPE ANY.
Did any one face this issue. Greatly appreciate any insight into this issue. We are on BW 3.0B.
the dump i'm getting is ...
Data objects in a Unicode program are not convertible.
Error analysis
The statement    "MOVE src TO dst"   requires the operands "dst" and "src" to be comvertible.
Since this statement occurs in a Unicode program, the special convertibility rules for Unicode programs apply.

Hi,
In the debugging this is what I found out.. Any further insight?
Virtual cube has only 1 characteristic Z_CRNUM & only 1 keyfigure Z_SR
Report has only Z_CRNUM & Z_SR
<L_S_DATA> has following record & value
component      type     length     contents
K____504     P     9     1.000
S____504     C     18     16EA4D-R
K____504 is the technical name of Z_SR in virtual provider.
S____504 is the technical name of Z_CRNUM in virtual provider.
E_T_DATA (type standard table) has following structure with a total of 5 fields.
S____504    K____504           &KEYEND 1ROWCOUNT   Z_SR

VIrtual Cube with user exit

Hi,
This is the Scenario :
Version : Bi 7 / Nw04s patch 11.
Source : ECC 6.
1) Virtual Cube V1 based on a generic Data source D1 in ECC or R/3 source system
2) The generic data Source has 10 fields , 7 are from a Standard Table, the 3 are populated during extraction via Transaction data User exit ZRS01*).
3) When I run the extractor checker for Data source D1 in R/3 all the 10 fields are populated.
4) Problem : when I do A list cube in BI on the virtual cube all te data in ECC is seen however the enhanced fields derived in the user exit are coming in as blank.
Any experience on this, whether this is a limitation of I need to create a message with SAP.
Would apreciate any thoughts or experience n this are,
thanks
TC

Check the user exit,if the code has been written to that specific datasource which was meant for the ODS(Watch out for case statements).

Virtual cube with function module

hi
I wrote function module which is used with virtual cube.
When I launch query build on this cube in the BEX i can't interrupt execution
of function module. How to put break point. may be there is any option that could turn off debugging?

Try an external breakpoint. How you set that depends on your version. If there's not a button for it on your editor screen, look at utilities->settings->ABAP Editor->debugging in SE38.

LAN side firewall settings for Direct Access (Windows Server 2012 R2) in DMZ?

I am currently planning to set up our first Direct Access server (Windows Server 2012 R2). I will be in our firewall DMZ and we will be using the IP-HTTPS listener.
For the Internet facing rule only TCP 443 inbound/outbound is sufficient but for the LAN facing rules (not talking about the Windows server firewall) what would be the recommended firewall rules for a Direct Access server? Is there a best practice guideline
to follow for this? Appreciate any advice or comments. Thank you.

Hi Barkley
Please see this Technet Link which will backup your requirements - https://technet.microsoft.com/en-gb/library/jj574101.aspx
Section Reads -
When using additional firewalls, apply the following internal network firewall exceptions for Remote Access traffic:
ISATAP—Protocol 41 inbound and outbound
TCP/UDP for all IPv4/IPv6 traffic
Also another link from http://www.ironnetworks.com/blog/directaccess-network-deployment-scenarios#.VO3tfvmsVrU
"I have had a number of conversations with security administrators and network architects who have expressed a desire to place the DirectAccess server between two firewalls (firewall sandwich) in order to explicitly control access from the DirectAccess
server to the internal corporate network. While at first this may sound like a sensible solution, it is often quite problematic and, in my opinion, does little to improve the overall security of the solution. Restricting network access from the DirectAccess
server to the internal LAN requires so many ports to be opened on the inside firewall that the benefit of having the firewall is greatly diminished. Placing the DirectAccess server’s internal network interface on the LAN unrestricted is the best configuration
in terms of supportability and provides the best user experience."
Kindest Regards
John Davies
Thank for your reply and information John. I find it somewhat disappointing that Microsoft does not provide much more in the way of documentation and information regarding this topic. I required more information to show to our security team so they will allow
us to have the internal facing NIC not have more restrictive rules in place as it is a security concern.
