BEX Exception with NetStream

Hi,
We have a flex component, which need to simultaneously stream upto 16 CCTV camera streams. We are using a Media Server(Wowza) to convert the RTSP stream to RTMP and display in flex.
Initially we tried the video display component, available with the flex framework..but when we were streaming more streams the application hanged and the PC monitor started to flicker. because some of the camera's will be not reachable in our deployment
Hence we removed the videodisplay component and wrote our own custom classes and add the video component at run-time. We are creating a single netconnection object and multiple netstream objects(one per CCTV/surveillance camera stream).
video = new Video(videoWidth, videoHeight);
video.name = "camerafeed";
video.attachNetStream(netStream);
addChild(video);
But after a while we are getting BEX (Buffer Overflow Exception)..
Appreciate if somebody can explain the maximum limit of the video component and the limits for the number of netstreams that can be created in one netconnection?.
Why is the VideoDisplay Flex component not able to switch between multiple camera's and display multiple streams?
Our PC is windows 7, having AMD Radeon H6650 graphics card.
Thanks,

Mavi:
Have you ever received a resolution to this error?
We have a user getting this on an infrequent basis... not consistently.
Any suggestions appreciated.

Problem about Bex Exception

Hi All,
I have some problems with bex exception. In my query, I have 3 columns (the third one is a rate calculated from the first (C1) and second columns (C2)). I have a characteristic in row which lists the different values. Sometimes, I have no value for C1 and C2 and also, the value rate is space (thatu2019s normal behaviour). I must highlight some rate by
If rate < 55         bad
If rate => 55      good
I did an exception
Bad        except1    BT      0 to 54
good      except2    GE      55
That works fine but my problem is :
The rate cells with a space value are also highlighted with the bad colour. Have you some idea to avoid this behaviour ?
C1                        C2                                                 Rate
1000                         5                                               200   (C3)
100                        20                                                5    (C3)
space                              space                               space   (C3)
1st C3 is green
2nd C3 is red
3rd C3 is also red (I want to leave blank)
Thanks fot your help.

Error an exception with the type CX_SY_CONVERSYION_NO NUMBER Occurred

Hi all
I am trying to execute a demand report,which is of normal complexity,means some selections,new formulas, 2 variables,around 10 characteristics/Key figures.
But this query thrwoing this error.and just disconnects from Bw server. with all users(means who ever access).The error is smae for all users.
Error the argumnet 10,00,000 cant be interpreted as a number
Error an exception with the type CX_SY_CONVERSYION_NO NUMBER Occurred
And starngely this query works fine in Dev/Qa.No error at all.
So i did the transport again 2 times from Qa -->Prod,but still the error remains the same in Prod.and just kicks out of system
Any possible advice here appreciated.Many Thanks.
Regds,
Preethi.

I had a request who works fine since one year and these last two days i have a CX_SY_EXPORT_NO_SHARED_MEMORY.
I tried many things like rebuild indexes, reload stats oracle .. but these actions didn't solve my problem.
I didn't want to modify parameter via RZ11 because this request was working fine before and the system is stable (no more user or more activity than the past)
I solved the situation by a deletion of Olap cache.
So:
Try to delete the OLAP cache by the RSRCACHE and reload again yu request (but be care because yu will erased the cache for all Bex request..)

Report on BEx query with 2 structures (one in rows and one in columns)

Hi, experts! I have to make Crystall report on BEx query with 2 structures, one in columns (with KF's), and one in rows. Is it possible to create such report? Because when I create such report, I cant see fields in structures, only characteristics fields.
Ok, I found samr problem in another thread. Sorry.
Edited by: Mikhail Sychev on Dec 5, 2009 9:53 PM

Hey Flora,
Happy to hear that its working now.
Answering your question, again its upto the connection and report format you are using. Based on your question i hope you your report output should be like this.
You cannot map to two labels for the series, again this report format is possible only in cross tab through Webi. I would suggest you to concatenate the material and month in a dimension in webi like below.
I have done the concatenation in excel level, i would suggest you to do that in webi. Try to reduce the formula as much in excel.
or
If you are using Query browser connection, then i would suggest you to create a separate report which will display the actual vs plan material wise, here you need to pass the material as a prompt.
Hope this helps in clear, please revert me for any clarification.

Exception with DefaultTableModel

Dear all,
I want to instatiate this class and add to my JTable. However, I can't make an instance of this.

Create a VC Model for BEx queries with Cell Editor

Hello All,
I am trying to create a VC Model for BEx queries with Cell Editor.
BW Development Team has created a BEX query with complex restrictions and calculations using Cell Editor feature of BI-BEX.
The query output in BEx analyzer is correct where all values are being calculated at each Cell level and being displayed.
But, while creating VC model, system is not displaying the Cells.Thus, no VC Model can be created.
I have executed below steps:
1. Created a VC Model for BEx Query - ZQRY_XYZ
2. Create Iview -> Create a dataService -> Provide a Table from the Output
In the Column field system is not showing any of the Cells (present in Cell Editor)
Please help me to solve this issue.
Thanks,
Siva

Hi
If 'Cell Editor' is been used then that query must have the structure in it. You have to select that 'structure' object in your 'VC Table'.
If you select that then you will get the required result in the output. This structure will be the structure where 'cell reference' is used in BI query, You have to select that structures name.

Exception with the type CX_SY_OPEN_SQL_DB occured and was not handled

Hi Champs,
I am working on an interface which picks up file uploaded in a XI server and process it. The Function module used is a Z function module, developed locally.
I am uploading an tab limited file in XI server and a background job processes the file. The tab limited file contains Payelement Transaction ID as primary key. And after validation of elements like WBS element, cost center etc the file is posted using BAPI BAPI_ACC_DOCUMENT_POST. And all the Payelement Trans Ids are also replicated in a Z table, with there status viz. Success or Error or Warning.
After background job was completed, we found in Tcode SXMB_MONI that the file was in error.
The error message was :
Error during proxy processing An exception with the type CX_SY_OPEN_SQL_DB occurred, but was neither handled locally, nor declared in a RAISING clause The system tried to insert a data record, even though a data record with the same primary key already exists.
But to my dismay, I found that some of the Payelement Trans Ids were posted for a document and are also replicated in my Z table.
From the error it seems that we are inserting a record that is already there in the document. I have checked in for BAPI's input parameter, there is nothing duplicate.
Note: Insertion in Z table is made after the BAPI BAPI_ACC_DOCUMENT_POST.
Can you help me out in this issue as it is now getting into veins
Reagrds,
Nishant

Hi,
Even we have faced this kind of issue. In order to solve this just write the following code:
1) Before inserting records in to Z table, write one select query on that table with primary key fields in where clause. Pass the value that are returned by BAPI BAPI_ACC_DOCUMENT_POST to the key field.
2) If sy-subrc = 4, insert records in Z table else Continue and dont insert records in this table.
This will solve your problem.

Prashant

Imac 27" Intel Core 7 CPU. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware scan and all is fine. Did clean wipe from Mavrick back

Imac 27" Intel Core7 CPU 16 Gig RAM. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware diagnostic and all is fine. Did clean wipe from Mavrick back to Mountain Lion but problem remains. Apple Store can do no more.

I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly...

PI - Proxy processing An exception with the type CX_SY_CONVERSION_NO_NUMBER

Hi All,
We have PI sync scenario,SOAP to Proxy.
We are geeting the below error in Proxy .
Error during proxy processing An exception with the type CX_SY_CONVERSION_NO_NUMBER occurred, but was neither handled locally, nor declared in a RAISING clause The argument ' 1,000.000' cannot be interpreted as a number.
But when the same data got updated in Proxy.Not sure about the root cause of the error.
Regards,
Arun

Hi ,
It looks like proxy is not able to convert string to number or the format of number is incorrect. This is only possible reason of this exception.
The argument ' 1,000.000' cannot be interpreted as a number.
Check out if the format is correct.. .

you are missing <backing-map-scheme>. Do like following:
<caching-schemes>
          <distributed-scheme>
               <scheme-name>distributed-scheme</scheme-name>
               <service-name>DistributedQueryCache</service-name>
               <backing-map-scheme>
                    <read-write-backing-map-scheme>
                         <scheme-ref>rw-bm</scheme-ref>
                    </read-write-backing-map-scheme>
               </backing-map-scheme>
<autostart>true</autostart>
          </distributed-scheme>
          <read-write-backing-map-scheme>
               <scheme-name>rw-bm</scheme-name>
<internal-cache-scheme>
     <local-scheme>
                    </local-scheme>
