Optimizer failure
Dear Optimizer Experts,
The scenario is like as follow -
Material X extended to location A & B, in optimizer we dont want X to be planned at A, therefore we have excluded location A from optimizer variant. But location B exist in variant because we want the planning at locaion B.
Now the optimizer is throwing error "Material master not created" & message no. /sapapo/snp042
For your information we have set the SDP relevance indicator to 1 for the location A.
Please share your valuable feedback.
Thanks
Sumit Kalyan
Hi Sumit,
Assuming that you are using a Cost Based Optimizer, there are number of ways to exclude Material A from picking up by the Optimizer, you can use anyone you feel is fit to meet your requirment.
1) Define a Very high Non delivery Penalty for Location B and zero Penalty for Location A
2) Block the transportation Lane for that Materials from Location A
3) Mark the Material at Location A as " Flag for deletion" this is to be done in ECC and then CIFed to APO
Try any of these options it should work.
Thanks,
Harsh

Any way to identify causes of Optimization failures ???
Hi guys
We have recently been seeing regular optimization failures (06:45 every morning - Lite optimization).
Unfortunately, the BPC logs only tell me that the job has failed, with no reason as to why it has failed.
This job runs every 2 hours on our system and the 06:45 job is the only one that fails with any regularity.
Is there any way that I can track what has actually gone on with the job, or am I stuck with only the job logs and EventViewer for information?
BTW - This is BPC 5.1 SP5
Thanks
CraigThere are definitely no scheduled jobs that clash with this one.
How do I check the "Master data"? (And indeed, what is the master data?)
I am not aware of any other jobs that run overnight on the server, other than this lite optimization every 2 hours and a full optimize.
The results (every day) are as follows:
00:45 - Lite Optimize - Success
02:45 - Lite Optimize - Success
03:30 - Full Optimize (no compression) - Success
04:45 - Lite Optimize - Success
06:45 - Lite Optimize - Failure
08:45 - Lite Optimize - Success
10:45 - Lite Optimize - Success
..... and so on throughout the day
The job succeeds almost every time it is run (with the odd exception of a dimension update which can clash with the 08:45 job if we are changing it at the time).
The only thing that changes before the 06:45 lite optimize is that the dependencies are dropped and recreated on each of the Fact tables:
INS1..., INS2..., INS3..., INS11..., INS21..., INS31..., DMU... for each Application
This is done because of a known issue in v5.1 which drops the dependencies of each application after a full optimize.
As for running the job again 30 minutes later - That works perfectly as well.
I just really need to know whether I have any way of finding out what other job(s) is/are running at the same time that could block the optimization, or whether the rebuilding of the dependencies could cause the issue (although that has been done for months on end without issue until now). -
Adobe Acrobat Pro 9 pdf optimizer failure..
We have a problem optimizing files in Acrobat Pro 9.
When we try to optimize (Advance > PDF Optimize) the file(s) Acrobat either chrashes, or just say "an error was encountered while processing images".
It is rather large files we have, from 50Mb to 112Mb and up to 17000 pages.
We cant split them into smaller files.
I can´t find anythin in the error log.
This happends on at least 4 computers, whit diffrent settings and hardware.
Any suggestions?
Thanks.You've likely exceeded your computers' capacity to process the necessary commands specified in the Optimizer settings chosen.
During optimization, a temp file will be created that is approximately the same size as the file being processed. The computer must be able to handle the additional load of each page being analyzed and processed. Text is not so bad, but layered images can be murder on memory.
There are some cases when an optimized pdf might actually end up being a larger file size than the original. Sometimes a simple Save As can dramatically reduce file size.
What is the goal of the optimization? How are you planning to distribute the document? Is there a reason for not providing multiple files instead of one large file? If you can give a few more details, some of the folks here might be able to give some helpful ideas.
FYI: A good article: "Understanding Acrobat's Optimizer" http://www.appligent.com/talkingpdf-understandingacrobatsoptimizer
It doesn't answer your question, but does provide good information about making optimizer choices -
Database performance is poor after upgrading to 9i
hi Guys
My system was upgraded to 9i by the third party after that I took over from that and I am getting the continuous complaints regarding performance of Database.
there are 150 Users who connects using citrix , from different locations and DB size is 20 GB.
this is my Init Ora file

I feel SGA size and Sort area size are not correct if we increase the value of both will it solve some my problem
AbhiI have run the some scripts to check the performance

Process dimensions and Applications after Restore
We are using BPC 7.0MS. We need to process dimensions and Applications after the database restore in case of any Optimization failures. It takes around 3 hours for us to do this process. Can we skip the BPC process by taking backup of Database and SSAS and restoring them in case of any failures?
Thanks
RajHi Raj,
you can try but remeber that after the restore you must execute a "modifiy application" for all your applications so maybe you'll not gain time.
Kind regards

OS X 10.4.4 DOWNLOAD HANGING AT "Optimizing System Performance" STAGE
I began downloading 10.4.4 update about 1.5 hours ago; most of the download executed fairly quickly--within 10 minutes. But then the download got to the "Optimizing System Performance" stage, and has been hanging in it ever since. It's accompanied by the spinning beach ball.
Is this common, or at least normal?
If not, what should I do? How long should I wait? I don't know if I can even get my iBook to force quit at this stage.
thanks in advance for your help.
T.W.Timothy,
What you are experiencing is not common or normal, but can hopefully be rectified.
According to iBook: If the Computer Won't Respond you can Force Quit by holding the power button for several seconds.
Restart from the Tiger Installation CD and run the Disk Utility as directed in the Try Disk Utility paragraph of Using Disk Utility and fsck to resolve startup issues or perform disk maintenance.
Next, attempt a normal startup of your computer.
Mac OS X: Troubleshooting installation and software updates says this about optimization failures:
Installation fails during "optimization"
If the installation fails during "optimization," all of the software was installed. There is no risk of an "incomplete installation." The optimization phase of an installation only affects performance and not stability or features. You may force optimization to be repeated by reinstalling the software. If you were using the Software Update pane of System Preferences on the first attempt, you will need to download the standalone installer of the same software from Apple Downloads in order to reinstall the software.;~) -
Hi,
We have encountered a similar failure in Optimizer background job for two days in a row. The Optimizer fails with an error which says "An Exception occurred in communication object.".
Please let me know if running a consistency check on APO database would be of any help to resolve this issue. Thank you.
RishikeshHi Rishikesh,
You could check if your optimizer server is reachable properly from SCM.
The issue coud most likely lie in Basis domain.
There is a SAP document on Optimizer setup, but unfortunately I can't attach it here.
I am copy pasting some things that could be checked by Basis team (Choose the Optimizer below that you use):
1. Log on to the SAP SCM System.
2. Call transaction SM59.
The Display and maintain RFC destinations screen appears.
3. Open the node for TCP/IP connection.
4. For the first optimizer server, you have to adapt the following RFC entries:
- OPTSERVER_CTM01
- OPTSERVER_DPS01
- OPTSERVER_SNP01
- OPTSERVER_SEQ01
- OPTSERVER_VSR01
- OPTSERVER_MMP01
- OPTSERVER_CS01
For the second optimizer server, the RFC entry names end with 02 (for example,
OPTSERVER_CTM02) and so on.
To adapt an RFC entry:
a. Double-click the destination name OPTSERVER_<Optimizer>01.
The RFC Destination OPTSERVER_<Optimizer>01 screen appears.
b. Depending on the server you must do the following to check the RFC entries:
A) Standalone Optimizer Server:
i. Choose Start on Explicit host.
ii. In the Program field check your program path (see table Program Paths of RFC Entries below).
iii. Check the name of your Target Host.
iv. Enter the number of the gateway host and the corresponding gateway service SAPGW<GW_NO>. You can find out the required parameters on your target host as follows:
a. On your target host, call transaction SMGW
b. Choose Goto u2192 Parameters u2192 Display (see entries for gateway hostname and gateway service)
v. Confirm with O.K.
B) Optimizer and SAP SCM on Same Server:
i. Choose Start on Application server.
ii. In the Program entry field check your program path (see table Program Paths of RFC Entries below).
If your SAP SCM server is an Unicode system, you must do the following in addition to the above setting for each OPTSERVER_<Optimizer>01 destination:
a. Choose the tab MDMP & Unicode.
b. In the group frame Communication Type With Target System you must select the flag Non-Unicode and the flag Inactive for the MDMP Settings box.
I hope this would be helpful in some basic check.
If your basis team is not able to resolve the issue, then better to reach out to SAP through OSS.
Thanks - Pawan -
G770 won't boot normally or in safe mode... I suspect it has something to do with the boot optimizer
My Lenovo G770 will not boot in normal or safe mode. I usually escape out of the boot optimizer. Today I let it run and it went to the "starting windows" screen with a brief startup of the windows 7 animation...it freezes for a second, then a quick flash of the bsod, then to the "windows error recovery page" giving me the option of "starting windows normally" or "Launch Startup Repair (recommended)."
Starting Windows Normally eventually brings me back to the same place repeating what I just stated above paragraph.
When I launch the Startup Repair it "Cannot repair this computer automatically".
So I go to view advanced options for system recovery and support.
It brings me to 5 options:
Startup Repair (we already tried this above)
System Restore (unfortunately I didn't create any restore points)
System Image Recovery (unfortunately I haven't created an image to recover)
Windows Memory Diagnostic (no problems found-done several times)
Command Prompt (don't know what I can do here except for remove a bad/corrupted driver which may be the problem, but I don't know the driver name that is associated with the boot optimizer...can anyone tell me this?)
I've tried booting to safe mode in all of its incarnations and I can't even do that..it repeats the same things as stated above...windows 7 animation briefly starts then locks up, flash of bsod, then the windows error recovery page.
I've tried booting to last known good configuration (same thing occurs...brief startup of windows 7 animation, freeze, flash of bsod, then error recovery page.
The only thing that has given me any kind of result was "disabling system restart on system failure." When I do this, the BSOD doesn't flash briefly..it stays. and it gives me the error message page_fault_in_nonpaged_area.
I'm at a loss as to what to do. Not being able to boot into Safe Mode even is really frustrating. Any advice from anyone? can I remove the driver associated with the boot optimizer? If so, what is the name of the driver and where (directory) is it located?How did you resolve the issue?
I have the exactly same issue.
When I go System Image Recovery -->Select System Image-->Advanced->I can open all the drives [:Local Drive(C , LENOVO(D, Local Disk(E, Boot(X-where i think executable booting is here]. It comes with an Open prompt asking me to enter File Name with a File type: Setup Information.
I don't know which setup information and where to find it on my Drives.
Anyone know how to fix?
I was trying to re-install Win 7 from DVD but it is not executing either.
Can I boot with USB Ubuntu and Install Win 7 from there??? but how?
Need help? -
How to run a do-while loop on the 2nd execution after a stop on failure occurs?
I am trying to use the Stop on Failure process model callback from the TestStand Examples.
If a step fails within a Do-While loop and the test is terminated, the second time the test is run (continuing to the Next UUT in the process model), the condition for the do-while loop is checked first before it ever enters the loop. This is incorrect because the Do-While loop should execute once and then check the "while" condition.
Also, If I was to stop the execution altogether and then restart the test (instead of continuing with the Next UUT), it runs the loop once, then checks the "while" condition.
I'm not sure if I am describing this clearly enough. The execution seems to flow like this:
Start test
Do
NumericTest step FAILS -> terminate
Next UUT starts
While (condition is false and skips over Numeric Test step).
So it seems that TestStand thinks it's still within that Do-While loop on the second execution and whatever runtime variables are not reset correctly.
Is this a TestStand bug? It happens in both TestStand 3.1 and 3.5.
Is there any way around this?
Thanks for any help.If it is what I think it is, it is a bug. Try unchecking Sequence Properties>>Optimize Non-Reentrant Calls to This Sequence and please tell me if that fixes it.

I need help diagnosing an issue where TCP communications breaks down between my host (Windows) and a PXI (LabVIEW RT 2010).
The bottom-line questions are these:
1...Are there circumstances in which TCP WRITE, given a string of say, 10 characters, will write more than zero and fewer than 10 characters to the connection? If so, what are those circumstances?
2...Is it risky to use a timeout value of 1 mSec? Further thought seems to say that I won't get a 1000 uSec timeout if we're using a 1-mSec timebase, but I don't know if that's true in the PXI.
Background:
On the PXI, I'm running a 100-Hz PID loop, controlling an engine. I measure the speed and torque, and control the speed and throttle. Along the way, I'm measuring 200 channels of misc stuff (analog, CAN, TCP instruments) at 10 Hz and sending gobs of info to the host (200 chans * 8 = 1600 bytes every 0.1 sec)
The host sends commands, the PXI responds.
The message protocol is a fixed-header, variable payload type: a message is a fixed 3-byte header, consisting of a U8 OpCode, and a U16 PAYLOAD SIZE field. I flatten some structure to a string, measure its size, and prepend the header and send it as one TCP WRITE. I receive in two TCP READs: one for the header, then I unflatten the header, read the PAYLOAD SIZE and then another read for that many more bytes.
The payload can thus be zero bytes: a TCP READ with a byte count of zero is legal and will succeed without error.
A test starts with establishing a connection, some configuration stuff, and then sampling starts. The 10-Hz data stream is shown on the host screen at 2-Hz as numeric indicators, or maybe selected channels in a chart.
At some point the user starts RECORDING, and the 10-Hz data goes into a queue for later writing to a file. This is while the engine is being driven thru a prescribed cycle of speed/torque target points.
The recording lasts for 20 or in some cases 40 minutes (24000 samples) and then recording stops, but sampling doesn't. Data is still coming in and charted. The user can then do some special operations, related to calibration checks and leak checks, and those results are remembered. Finally, they hit the DONE button, and the whole mess gets written to a file.
All of this has worked fine for several years, but as the system is growing (more devices, more channels, more code), a problem has cropped up: the two ends are occasionally getting out of synch.
The test itself, and all the configuration stuff before, is working perfectly. The measurement immediately after the test is good. At some point after that, it goes south. The log shows the PXI sending results for operations that were not requested. The data in those results is garbage; 1.92648920e-299 and such numbers, resulting from interpreting random stuff as a DBL.
After I write the file, the connection is broken, the next test re-establishes it, and all is well again.
In chasing all this, I've triple-checked that all my SENDs are MEASURING the size of the payload before sending it. Two possibilities have come up:
1... There is a message with a payload over 64k. If my sender were presented with a string of length 65537, it would convert that to a U16 of value 1, and the receiver would expect 1 byte. The receiver would then expect another header, but this data comes instead, and we're off the rails.
I don't believe that's happening. Most of the messages are fewer than 20 bytes payload, the data block is 1600 or so, I see no evidence for such a thing to happen.
2... The PXI is failing, under certain circumstances, to send the whole message given to TCP WRITE. If it sent out a header promising 20 more bytes, but only delivered 10, then the receiver would see the header and expect 20 more. 10 would come immediately, but whatever the NEXT message was, it's header would be construed as part of the payload of the first message, and we're off the rails.
Unfortunately, I am not checking the error return from TCP write, since it never failed in my testing here (I know, twenty lashes for me).
It also occurs to me that I am giving it a 1-mSec timeout value, since I'm in a 100-Hz loop. Perhaps I should have separated the TCP stuff into a separate thread. In any case, maybe I don't get a full 1000 uSec, due to clock resolution issues.
That means that TCP WRITE cannot get the data written before the TIMEOUT expires, but it has written part of it.
I suspect, but the logs don't prove, that the point of failure is when they hit the DONE button. The general CPU usage on the PXI is 2-5% but at that point there are 12-15 DAQ domain managers to be shutting down, so the instantaneous CPU load is high. If that happens to coincide with a message going out, well, maybe the problem crops up. It doesn't happen every time.
So I repeat the two questions:
1...Are there circumstances in which TCP WRITE, given a string of say, 10 characters, will write more than zero and fewer than 10 characters to the connection? If so, what are those circumstances?
2...Is it risky to use a timeout value of 1 mSec? Further thought seems to say that I won't get a 1000 uSec timeout if we're using a 1-mSec timebase, but I don't know if that's true in the PXI.
Thanks,

Blog for (mostly LabVIEW) programmers: Tips And Tricks
Solved!
Go to Solution.There are a couple of issues at play here, and both are working together to cause your issue(s).
1) LV RT will suspend the TCP thread when your CPU utilization goes up to 100%. When this happens, your connection to the outside world simply goes away and your communications can get pretty screwed up. (More here)
Unless you create some form of very robust resend and timeout strategy your only other solution would be to find a way to keep your CPU from maxing out. This may be through the use of some scheduler to limit how many processes are running at a particular time or other code optimization. Any way you look at it, 100% CPU = Loss of TCP comms.
2) The standard method of TCP communication shown in all examples I have seen to date uses a similar method to transfer data where a header is sent with the data payload size to follow.
<packet 1 payload size (2 bytes)><packet 1 payload..........><packet 2 payload size (2 bytes)><packet 2 payload.......................>
On the Rx side, the header is read, the payload size extracted then a TCP read is set with the desired size. Under normal circumstances this works very well and is a particularly efficent method of transferring data. When you suspend the TCP thread during a Rx operation, this header can get corrupted and pass the TCP Read a bad payload size due to a timeout on the previous read. As an example the header read expects 20 bytes but due to the TCP thread suspension only gets 10 before the timeout. The TCP Read returns only those 10 bytes, leaving the other 10 bytes in the Rx buffer for the next read operation. The subsequent TCP Read now gets the first 2 bytes from the remaining data payload (10 bytes) still in the buffer. This gives you a further bad payload read size and the process continues OR if you happen to get a huge number back, when you try to allocate a gigantic TCP receive buffer, you get an out of memory error.
The issue now is that your communications are out of sync. The Rx end is not interpeting the correct bytes as the header thus this timeout or bad data payload behavior can continue for quite a long time. I have found that occasionally (although very rare) the system will fall back into sync however it really is a crap shoot at this point.
I more robust way of dealing with the communication issue is to change your TCP read to terminate on a CRLF as opposed to the number of bytes or timeout (The TCP Read has an enum selctor for switching the mode. In this instance, whenever a CRLF is seen, the TCP Read will immediately terminate and return data. If the payload is corrupted, then it will fail to be parsed correctly or would encounter a checksum failure and be discarded or a resend request issued. In either case, the communications link will automatically fall back into sync between the Tx and Rx side. The one other thing that you must do is to encode your data to ensure that no CRLF characters exist in the payload. Base64 encode/decode works well. You do give up some bandwith due to the B64 strings being longer, however the fact that the comm link is now self syncing is normally a worthwhile sacrifice.
When running on any other platform other than RT, the <header><payload> method of transmitting data works fine as TCP guarantees transmission of the data, however on RT platforms due to the suspension of the TCP thread on high CPU excursions this method fails miserably. -
Optimization bug with C++ inlining
Hi,
While evaluating Sun Studio 11 I have identified an optimization bug with C++ inlining.
The bug can easily be reproduced with the small program below. The program produces
wrong results with -xO2, because an inline access function always returns the value 0.0
instead of the value given on the commandline:
djerba{ru}16 : CC -o polybug polybug.cc
djerba{ru}17 : ./polybug 1.0
coeff(0): 1.000000
djerba{ru}18 : CC -o polybug -xO2 polybug.cc
djerba{ru}19 : ./polybug 1.0
coeff(0): 0.000000 <<<<<<<<<< wrong, should be 1.000000This occurs only with optimization level O2; levels below or above O2 don't
exhibit the bug.
Compiler version is
Sun C++ 5.8 Patch 121017-01 2005/12/11
on Solaris 8 / Sparc.
I include a preliminary analysis at the end.
Best Regards
Dieter R.
-------------------- polybug.cc -------------------------
// note: this may look strange, but this is a heavily stripped down
// version of actual working application code...
#include <stdio.h>
#include <stdlib.h>
class Poly {
public:
// constructor initializes number of valid coefficients to zero:
Poly() { numvalid = 0; };
~Poly() {};
// returns coefficient with index j, if valid. Otherwise returns 0.0:
double coeff(int j) {
if (j < numvalid) {
return coefficients[j];
} else {
return 0.0;
// copies contents of this Object to other Poly:
void getPoly(Poly& q) { q = *this; };
// data members:
// valid coefficients: 0 ... (numvalid - 1)
double coefficients[6];
int numvalid;
void troublefunc(Poly* pC) {
// copies Poly-Object to local Poly, extracts coefficient
// with index 0 and prints it. Should be the value given
// on commandline.
// Poly constructor, getPoly and coeff are all inline!
if (pC) {
Poly pol;
pC->getPoly(pol);
printf("coeff(0): %f\n",pol.coeff(0));
int main(int argc,char* argv[]) {
double d = atof(argv[1]);
// creates Poly object and fills coefficient with index
// 0 with the value given on commandline
Poly* pC = new Poly;
pC->coefficients[0] = d;
pC->numvalid = 1;
troublefunc(pC);
return 0;
The disassembly fragment below shows that the access function coeff(0), instead
of retrieving coefficient[0] simply returns the fixed value 0.0 (presumably because the
optimizer "thinks" numvalid holds still the value 0 from the constructor and that therefore
the comparison "if (i < numvalid)" can be omitted).
Note: disassembly created from code compiled with -features=no%except for simplicity!

Hmmm... This seems to stress this formatting tags thing to its limits...Thanks for confirming this.
No, this happens neither in an Open Source package nor in an important product. This is an internal product, which is continuously developed with Sun Tools since 1992 (with incidents like this one being very rare).
I am a bit concerned with this bug though, because it might indicate a weakness in the area of C++ inlining (after all, the compiler fails to correctly aggregate a sequence of three fairly simple inline functions, something which is quite common in our application). If, on the other hand, this is a singular failure caused by unique circumstances which we have hit by sheer (un)luck, it is always possible to work around this: explicitly defining a assignment operator instead of relying on the compiler-generated one is sufficient to make the bug go away. -
Mac Hard Drive Failure - How to get all info of iphone?
The computer that I sync my iphone to had a complete system drive failure. The drive is toast, nothing recoverable. There is lots of information that I have on my iphone that I now only have on my iphone: mail, contacts, notes, pictures. I want to keep all of this information, but I haven't been able to find a way to get it off the iphone.
If I sync to the fresh OSX install on the computer that failed, or one of my other macs, the iphone gets wiped squeaky clean. I obviously don't want this to occur. Does anyone know a way to create an iphone backup on a computer other than the one the iphone is set to sync to, or is there a way to access the iphone as a disk and copy the information?
Any help would be appreciated.
And yes, I have learned the "backup frequently" lesson.This is one reason why maintaining a backup is so important. The iPhone does not support disk mode, and is not designed nor intended to be a backup storage device.
If I sync to the fresh OSX install on the computer that failed, or one of my other macs, the iphone gets wiped squeaky clean.
Not true. In regards to iTunes content, an iPhone can be synced or manually managed with an iTunes library on a single computer only, and photos can be transferred from a single computer only. When transferring iTunes content and photos from another computer, all iTunes content and photos transferred from a different computer will be erased from the iPhone first, but no other content on the iPhone will be touched. Contacts, calendar events, and Safari bookmarks can be synced with the supports applications on multiple computers.
iTunes includes an option to transfer iTunes content that was purchased or downloaded from the iTunes store from an iPod or iPhone, but this is for iTunes content that was purchase or downloaded from the iTunes store only.
With your iPhone connected to iTunes on the Mac you plan on using to sync your iPhone with, first you need to authorize the Mac with your iTunes account with iTunes if your haven't already done so. Without syncing, at the iTunes menu bar go to File and select Transfer Purchases From - the name of your iPhone. If all 3rd party apps do not transfer, you can re-download a 3rd party app with iTunes on the Mac and you won't be charged again for a purchased app as long as you use the same iTunes account to re-download the app that was used to purchase the app originally.
Photos transferred to an iPhone is a one way transfer process only. Photos transferred to an iPhone are optimize for viewing on the iPhone as part of the iTunes sync/transfer process only - the original resolution of these photos is reduced, which is why Apple doesn't transferring these photos in the opposite direction, and why including these photos with your computer's backup is important.
There are some 3rd party apps that support transferring these photos in the opposite direction and if successful, the original resolution of these photos will be lost.
Before syncing contacts with the Address Book and calendar events with iCal on this Mac if there are no contacts in the Address Book and no calendar events in iCal - both are empty, enter one contact in the Address Book and one calendar event in iCal - make these up if needed, which can be deleted later. This will provide a merge prompt when syncing this data, which you want to select.
Backup, backup, bakcup backup, backup, backup.

Failure Writing file...Report processing has been canceled by user
I'm having a bit of an odd issue. In my SCOM environment I have 8 scheduled reports that management likes to look at. 7 of them are working just fine, however one of them keeps failing with the status:
"Failure writing file <file name> : Report processing has been canceled by the user."
Now this report is running every Sunday at 2:30 AM and I can assure you I am not up administering reports at 2:30 am on a Sunday.
Except for the file name this is set up identically to one of the reports that is working fine. If I write click and "run" the report it generates, though it takes a few minutes, and I can save it as an excel file to where we want it. There's nothing
in the event log around the time it says it last ran (2:30:03 AM).
Any ideas?Hi Dave,
Could be conflicting with this built maintenance at 2:30am:
There is a rule in the System Center Internal Library called "Optimize Indexes". This rule runs every night at 2:30am on the RMS and calls p_OptimizeIndexes. Make sure any standard maintenance you perform on the OpsMgr DB does not interfere
with this job.

Did you look at SQL Reporting Services Logs?
As well, you can try to change the Report Execution TimeOut in Report Manager.
