Precalculation server: problem with precalculation of a single workbook

Hi all,
We noticed a strange error while precalculating a workbook. Broadcasting to portal (or sending via E-Mail) of this workbook always fails with the following error text:

Other workbooks work fine. I've already created a new precalculation server but it didn't help. Has anyone an idea what could be the cause or why this just happens with this workbook?
Any advice could be helpful.

Chrigu

Hello All,
When you have an issue with a single workbook, try to open and re-save this workbook.
This is probably happens with Chrigu. Someone opened the workbook and save again.
Also, another tip.
Open BEx Analyzer -> Click on "Global Settings".
Check the option "Repair workbook while execution" -> click "Ok"
Execute and save the workbook.
This should solve issues with a single workbook.

Issue when Bursting reports via new Precalculation Server

Hello,
We are trying to migrate away from our unsupported 720 installation of the SAP Precalculation software to a new Precalculation Server running the latest versions. We’ve overcome a number of issues and we can successfully Broadcast using the new server but we are encountering problems
with bursting.
The Bursts have been running successfully on the old 720 server, so we know that the BW side must be fine which suggests the problem is with the Precalculation server. We have been through the Precalculation checklist and the servers appears to have been built successfully. The Precalculation and Business Explorer software has been patched to the latest version and it’s running Excel 2013.
The main error message we are seeing is “The RPC server is unavailable” HRESULT: 0x800706BA.
A Screen shot showing the error in RSRD_LOG is shown in the attached document.
Below is an extract from the Log of the Precalc server showing this error, just before the RPC Server is unavailable message it states
Error occured on closing opened workbooks.

Hi,
There is no easy fix for this. Please go through the precalc check list which should solve the issue:

Regarding BW precalculation server monitoring

Hi Experts, we have BW precalculation server configured in pur NW2004s BW system. My requirement is if i can monitor RSPRECADMIN using Solution manager. Like if precalc server goes down it should generate an alert.
Any inputs on the above would be much appreciated.
Thanks Amber S

As indicated [earlier here in SDN|How to monitor Bi Precalculation?;,there is no MTE for monitoring Precalc. The work-around is to monitor the BI RFC PREC_<SID>. This provides a better end-to-end check than simply checking the Windows service on the Precalc server. Rather than monitor the RFC on the remote system, I simply created a duplicate of the RFC on the Solution Manager system, and monitored that.
See [Monitoring Availability of Services|http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/70531389-0c01-0010-2a95-c019524764ae] (PDF) for a description of RFC monitoring.
Also, here are some notes on data collection method CCMS_RFCDest_Availability_Col:
SAP Note:0570083 CCMS: RFC Destination Monitoring does not work
SAP Note:0771455 CCMS: Incorrect MTE Class in RFC Destination Monitoring
SAP Note:0696194 CCMS: MTE class specification in SALK_RFCDEST_AVAILABILITY

Precalculation Server error after 10 broadcasted workbooks

Hi gurus,
i have a question concerning broadcasting workbooks. We are using the newest precalculation server with patch 13. The first 10 workbooks are calculated and sent via email. The rest of workbooks calculated are sent as a job but the RSRD_Log transaction shows an error. It begins with "Unresolved exception occured in the precalculation server" then next message "System.Runtime.InteropServices.comException. The RPC server is unavailable (Exception from HRESULT:xxxxxx) "
Then some other messages are displayed. Then at the end it says cannot precalculate Workbook. In rsprecadmin the server is green and ready.
Is there any restrictionin sending via Email?
How can i get the server again to continue sending?
How can i clear the queue, to get the precalculation server ready to continue scheduled workbooks?
Thanks and kind regadrs,
Murat

Hi Edward,
we are testing the broadcast functionality and we want to go live first week in september. I hope you remember and suggested me the note which came out in CW33 with the precalculation server patch 13 . we are using it but still NVs but there is also the issue with the sizing. Last night we scheduled 16 times the same workbook.All 5 minutes one workbook should be sent out. 2 Precalculation server were set up to deal with them. In the SAP document "How to ...Troubleshoot Information Broadcasting (BEx Workbooks)" in chapter 2 it is mentioned that when ycurrently you can have 10 workbooks in the queue. Therefore we set up 2 precalculation server with 10 workbooks capacity. Then we set in the Broadcast setting the load balancing option without selecting any precalculation server. My intention would be the first 10 workbooks should be broadcasted with one of the precalculation server. After he has reached his capacity the next workbooks would be broadcasted with the second precalculation server. Am i wrong?
When i check the queue i see the 16 workbooks in "Queue Overview of Proccessed Error-Free Precalculations" but with a duration with 0 seconds. the log says in RSRD_LOG says as described before the first message is "Unresolved exception occurred on the precalculation server" then "System.Runtime.InteropServices.COMException (0x800 0706BA): The RPC server is unavailable. (Exception" and at the end "Cannot precalculate workbook ZBROADCAST_TEST". I can see that when load balancing the second server is not used.
But while seraching for precalculation server it says "Precalculation server PRECALC_2 has only 0 free instanzen => not selected" but why. it has never been used why 0 instances free?

BI Precalculation Server for BI 7.0 (SAP GUI 710)? Not Available?

We recently upgraded from BW 3.5 to BI 7.0 SP 15. To support other SAP company initiatives, we also upgraded all SAP GUIs to 710.
Is there no updated BI Precalculation Server for BI 7.0 with SAP GUI 710? Can we use older precalculation software with BI 7.0? Or do we have to wait until SAP publishes the precalc server for GUI 710 (as indicated by note # 1013205)? Anyone know when that might be?

I created opened a message with SAP and here is the response I got back:
Dear Customer,
Currently SAP GUI 7.10 is not supported with Precalulation service.
As per Note: 1013205 Pre-Requisite for BI Precalculation service 710

Is Precalculation server a prerequisite for Information broadcasting

Hello Everybody,
I wanted to know is installation and configuration of pecalculation server a prerequisite for enabling Information broadcasting feature in BW 3.5 i.e; inorder to send emails to users .I mean inorder to send mails to users is it necessary to install pecalculation server first.
Regards,
Saumya

The Precalculation server is only needed if you want to distribute workbooks. In order to distribute workbooks, the BW needs access to a computer with Excel on it. The precacluation server service software can be installed on a standard desktop PC. It can be installed on mutliple desktops, or you can consider a centralized server, but for initial testing, a desktop will do. There are a number of OSS Notes to apply, several from SP 17 that deal with problems occuring as a result trying to distribute multiple wkbks simultaneoulsy.
You do NOT need it to distribute either query links or html formatted output.
You also need an IGS server if you want to be able to send your output in a zip file format.
Don't have the link handy, but try searching SDN on Precacluation Server - there is a good paper (think it was a How To...) that was just written in April on troubleshooting Precalculation Server issues.

Precalculation Server for Information Broadcasting

Hi Folks,
Do we need Precalculation server to use Information Broadcasting in BW7.0?
I am especially interested in using the Filling OLAP Cache functionality in Information Broadcasting to fill OLAP cache for one workbook.
Need your help on this.
Regards,
Sn

Hi Raghavendra \ NS,
We have only one application server. The issue might be because of the broadcast settings which I am giving to fill the OLAP Cache.
In my current query there are two variables one is on business unit and the other one is on calendar month. Both the variables are optional.
Business Unit variable accepts multiple single values as input and the calendar month is selection-option variable.
Now My problem is if I fill cache with a variant, without providing any value for Business Unit variable (i.e for all the business Units ) and Calendar month values as 01.2010 to 11.2010, then when I execute the query for Business Unit x and Calendar month 10.2010- this is not picking data from cache instead reading from the database. Ideally this selection is the subset of the cache which I have filled.
The query is picking data from the cache only if I give the same variable values i.e no values for Business Unit and 01.2010 to 11.2010 for calendarmonth.
My requirement is to fill the cache for all the Business Units and all the calendar months of current year. This cache should be accessed by the query even if user selects one or multiple or all the Business Units and a single or range or all the calendar months of current year.
I might be doing something wrong in settings of BEx broadcaster. Please throw some light on the settings which I have to make in this case.
Regards,
SN

Workbook - Precalculation server

Hi,
W consider publishing workbooks in our SAP BI Portal. (BW/NW Portal 7.0).
Is it mandatory to install the precalculation server or can we publish workbooks with out installing this server component?
- What's tha advantage/disadvantages?

Hello,
Yes, it is mandatory a precalc. Server if you want to publish Workbooks. There is no other way.
However, you can publish queries without a Precalculation Server.
So, you can publish the queries used on the workbooks without a precalc. server. This is only a workaround.
Thank you for your attention.
Best regards,
Edward John

Sizing of precalculation server and workbook description while broadcasting

Hello Gurus,
First
i have a question concerning broadcasting. First we installed one precalculation server on a desktop but after creation a lot of settings for broadcasting a workbook the sending vial email or portal did not show the workbook (numbers, textitems) correctly. I just saw NV for the numbers.
Then i deleted the broadcast settings from transaction RSRD_ADIM. After created one setting again after the deletion of all the settings i broadcasted one workbook via email successful. --> my suggestion was that it depends on the settings created for a precalculation server. Sizing is a problem, broadcasting the workbooks correctly. is there a relationship one precalculation server how many workbook broadcast settings?
Second when i broadcast a workbook via Email the name of the attached file is:
WORKBOOK_XXXXXXXXXXXXXXXtechnical nameXXXXXXXX.XLS
This name is meaningless. Is there a possibility to change the name of the of the broadcasting file?
Thanks and kind regards,
Murat

Hi Murat,
First: yes, there is a limitation on how many workbooks a precalculation server can process at once.
The older load balancing server version (see note 1275837) had the following environment variable to control how many instances it should start at a given time:
(Control Panel -> System -> Advanced -> Environment Variables) BEX_PRECALC_INSTANCES = 1. In this case, only one instance would be started at a time (that is, a workbook would be processed after another).
Second: No. It is not possible. I had a request here at SAP some time ago and the development said that it is just working as designed and no plans to develop such functionality were ongoing at that time.
Kind Regards,
Marcio

Information needed for Precalculation Server

Hi All,
I am installing Precalculation server for BI Broadcasting. Can i use only 1 Precalculation server for DEV, QA and PRD OR i should use 3 individual precalculation server for DEV, QA, PRD.
Thanks

Hi Simon,
As per my investigation I found, we should use only one server per BW system. If we want to use same precalculation server for multiple BW system, we should use Virtual Machine on precalculation server. Any comment?
Other thing is as you mentioned we should consider this server as any other server, but precalculatin server is nothing but few services that runs on Windows. So do we have to treat this server same as any other SAP system?
Thanks

Precalculation server - Information Broadcasting

Friends,
I want to shedule and send query result throught Email in Excel format.
1) Do I need Precalculation server running?
I checked in the Tcode RSPRECADMIN. There is no Precalculation server existing in our system. so I created one by clicking on create button. But I'm not able to start.
2) How to start the server.
It is bit urgent pls respond.
Joe.

There is a precalculation service (the setup file for this is now in the BI frontend installation CD) that will need to be installed on the PC. It will install itself as a windows service on that PC.
From that system, you can then create the Precalc server as you created. It will define the necessary RFC connections, and show the server in 'green' (if the windows service for precalc is running in your PC which it should be).
Without that part, defining a server in RSPRECADMIN won't do a thing.
