Time Sparsity and Gaps in Data ???
Hi,
I have a cube with 7 dimensions and having over 70 million rows. I have made all dimensions including time to be sparse. Now the problem is that there are gaps in my data for certain days after I maintain cube, which seems strange. Also, the aggregation at lower levels(days) is not correct whereas aggregations on higher levels (like year) are absolutely correct.
On the other hand, if i dont make time dimension sparse then there are no gaps in data and everything looks fine. All aggregations are fine in this case in every level.
Can any1 explain this behaviour please ?
Regards.
Hi Riccardo:
At your suggestion, I used the Convert From Dynamice Data to 2D array before saving the array using Write to Spreadsheet File. When I collected 2 seconds of data at 1,000 Hz, there are fewer than 200 lines of data in the spreadsheet file (no gaps in the data, see the txt file attached). For comparison, the file saved using Write to Measurement File has close to 1,000 lines (with gaps in the data, see the xlsx file attached). Thanks for your time.
John

Can I use an external drive for Time Machine and storing other data?
At the moment I have one external drive, a 500gb LaCie. My internal drive is 160gb. I don't think I'll be using all 500 of those gigabytes for a while, so I want to put them to good use. Can I make a partition on this drive and use that for Time Machine, leaving the rest of the drive for my documents and other files? If so, how would I partition the drive? I'm not fluent in Disk Utility and even though I'm pretty sure I know how to do it, I don't want to screw up. Also, how big a partition would you recommend?
While we're here, I have a second question, somewhat relevant to the first. Could I move my Time Machine backups to a second drive if I wanted to? Also, if I used a big drive (say 1tb) could I use Time Machine to backup my current LaCie to a partition on that drive? Thanks in advance.videoCWK wrote:
Does that also mean that I could back them both up on a very big drive?
Yes. Time Machine will, by default, back up all of your external drives unless you specifically exclude them.
Also, will Time Machine backups eat all my space after a lot of usage?
It depends on what you do on your Mac. If you work often with very large files (video editing, heavy photo editing, big disk images, Microsoft Entourage data file, Parallels disk image file, etc) then your backup drive could fill up very quickly.
I use my Mac mostly for e-mail, web browsing, iTunes, iPhoto, and the occasional iMovie project. I have 92 GB on my main hard drive (60 GB of which are my iTunes and iPhoto libraries, and one iMovie project.) My Time Machine backups consume 155GB on my backup drive, and that's after using Time Machine for a full year. -
Retrieve date, time, guid and user id data from IP u2013wrong mapping of fields
Hi
I have used the How to guide Line Items in BI Integrated Planning to implement the functionality to save the username, guid, date and time of who is planning. I do not get any errors but the field 0uname is empty and the guid field gets the username of the planner (0uname). The date and time field get populated correctly. Why does the fieldu2019s username and guid populated incorrectly? Do I have to change the code (I just copied the code from the How to document)? To me the abap code looks correct.
We use BI 7.0 and SPS 17.
Kind regards
ErikTry this: Just replace the objects for ...LOGD = date, ...LOGT = time and ...LOGU = User:
FIELD-SYMBOLS: <l_chavl> TYPE ANY,
<l_curk> TYPE ANY.
ASSIGN COMPONENT '/BIC/M2PLOGD' OF STRUCTURE c_s_chas to <l_chavl>.
<l_chavl> = sy-datlo.
ASSIGN COMPONENT '/BIC/M2PLOGT' OF STRUCTURE c_s_chas to <l_chavl>.
<l_chavl> = sy-timlo.

Customer and Vendor Master Data.
Hi,
Can any body plz tell me how the customer and vendor master data created in real time implementation and the master data's are created by FI CO consultants.
And plz. tell me the procedure
Thank youHi
In Real Time Master Data team will look into Creation of the Master data.This will be as same as how you create in a training class.For every external party with whom we do business must be created as a Vendor or a Customer.The system offers seperate functions for maintaining Customer Master Records and Vendor Master Records depending on the requirements of your Organization.
A Complete Customer Account consists of General Data at the Client Level , Company Code Segment and Sales Area Segment.These Data records can be maintained Centrally for all areas or seperately for Financial Accounting and Sales and Distribution.
A Complete Vendor Account consists of General Data at the Client Level , Company Code Segment and Purchase Organization Segment.Vendor Master Records can be maintained Centrally for all areas or seperately for Financial Accounting and Materials Management.

How to create a loop to run total of records for before and after unconstant date
Post Author: Ann2
CA Forum: Formula
Here is the data sample:
ID period code date
1 00 I 01/01/1999
1 00 Z 01/02/1999
1 00 G 12/05/1999
1 00 M 01/01/2000
There are many students with many periods and many codes. I need to save a date when code = 'G' and count separateley records per student/period 2 times - before and equal that date and after that date, so in the end for period 00 I will have 2 values: 3 (before) and 1(after).
There are periods from 00 to 08. I am counting students abscencies before and after warning letter was sent (code G).
The result data should look : 00 01 02 03 04 05 06 07 08 00 01 02 03 04 05 06 07 08 Total
3 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 4
Please help me.
Thank you.

Thank you for your answer, but I do care about the date the 'G' happened, because I need to reset count.
The logic behind is this:if a student absent for more than 8 times per period - the letter will be sent out to the parents , that will be code 'G' with period '-1' (it may happen that there will never be code 'G' , but I need to track all absencies). Once the letter is sent, the count starts over (the count starts over the next day after code 'G'). The absencies which happened before or the date the letter sent should count toward 'previous' abscenices, all other - absenices after the letter.
So basically I need total per period and total per period before or the day with code 'G'. Running total with reset with formula code = 'G' does not work.
I created a formula field which has global date (when code 'G' happenned) and it says if globaldate >= periodDate then date (1900,01,01) else (2100,01,01) and that formula is ok, but I can not use it in running total or can not create group on it and insert total.
Please help me with this. Thank you.

I have this doubt. I've just bought an external drive, especifically a Seagate GoFlex Desk 3 tb.
I want to know if it is recomendable to make a partion exclusively for time machine and let another one so I can put there music, photos, videos, etc that I should need to use or copy to another computer.
May half and half, 1.5 tb for time machine and 1.5 tb for data.
I have an internal hard drive of 500 GB (499.25 GB) in my macbook pro.
Any recommendation?As I said, yes. Be sure your Time Machine partition has at least 1 TB for backups.
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to two (2). Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. -
How can I restore my data from iCal? I didn't make any backup, but I use time machine with an external HD. I deleted iCal when I deleted my gmail account. I have tried to restore, but I can only restore the iCal software and not the data.
So what is your question?
If you forgot your encryption password:
Warning: Make sure it's a password you will remember or write it down for safekeeping. If you encrypt an iPhone backup in iTunes and forget your password, you can't restore from backup and your data will be unrecoverable.
If you can't remember the password and want to start again, you must perform a full software restore and chooseset up as a new device when iTunes prompts you to select the backup from which to restore.
The above comes from here:

Trying to restore after getting a new hard drive. I can see the backup on the Time Capsule and on the correct date but it is Greyed out. That is it wont let me open it and restore the machine. Have tried also Migration Assistant, no luck.

At startup hold down the Command+Option/Alt+r keys until you see a globe on the screen. Then use disk utility to partition and format the drive HSF+ and then select Reinstall Mac OS X. whatever version of OS X that originally came on your system will be installed and then you can upgrade back to Mavericks. -
Missing Pictures.
Have made a rebbot from Time Machine, and now I lack a lot of pictures. Can see icons, but not enlarge them. Especially pictures where 2009 is included in the date is missing?
When I set up my desktop, I can find some of the pictures. Where do They hide, and what shall I do.
Have made back up, but unfortunately a little too late. What to do?
MacBook Pro 15 "late 2008, Processor 2.53 Ghz Intel Core 2 Duo, Graphics NVIDIA GeForce 9400M 256 MB, Software Mac OS X 10.7.4 Lion (11E53).1. You did not get an error message telling you that your iPhoto library was getting full. You got a message telling you that your HD was getting full, right?
OS X needs about 10 gigs of hard drive space for normal OS operations - things like virtual memory, temporary files and so on.
Without this space your Mac will slow down as the OS hunts for space on the disk, files will be fragmented, also slowing things down, apps will crash and the risk of data corruption - that is damage to your files, photos, music - increases exponentially.
Your first priority is to make more space on that HD. Nothing else can be done until you do.
Purchase an external HD and move your Photos and Music to it. Both iPhoto and iTunes can run perfectly well with the Library on an external disk.
Your Library has been damaged from being run on an overfull disk.
How much free space on it now? -
My iMessage for my Macbook Air is not working. I have updated everything. My system is running on OS X Yosemite Version 10.10. When I go to send a message, it says no delivered with a next to it. I have tried serval different options on trying to get it to work to include logging out of iCloud and checking my date and time and updating FlashPlayer. I have done about everything I can think of. Any help would be greatly appreciate!

So I have just had my potentially duff 1Tb hard drive replaced by apple and uploaded my data from time machine only to discover that pages is now speaking to me in a different language. The keyboard has been selected as UK during setup. Any idea how I can get back to qwerty?
roxandiv wrote:

What exactly are you referring to? Are the menus or templates for Pages in a different language? Does something strange appear on the screen when you type?
Could you perhaps use the Camera icon here to post a screenshot of what you are seeing?
To make sure you have the right keyboard, go to system preferences/language & text/input sources and make sure that only the box for US or British is checked (and that the box for French or German or anything else is not checked). -
Time capsule deleted all my data and overwrote it with a backup
I found Time Capsule in finder and it let me create a folder and put my stuff in it. I was using it as an auxilliary hard-drive right next to the backups.
I put DVD installation media, old files, student work history, and a lot of stuff on there.
Time Capsule decided to delete all of my data one day to make room for a backup.
People should know this.
Do not put anything on your Time Capsule that you want to keep, unless perhaps it's on another partition (if that works).
I'm not too disappointed about it as it wasn't my critical stuff, but still. It's lost forever now.
And it's supposed to be a Time Capsule for @#($*%& sake.JKMarshal wrote:

That's not a good idea. See #Q3 in Using Time Machine with a Time Capsule for details.
Time Capsule decided to delete all of my data one day to make room for a backup.
No, it didn't. Time Machine cannot delete other data to make room for backups.
Under extreme circumstances, when it finds your backups corrrupted beyond repair, it may delete all your Time Machine Backups, but not until you confirm via this prompt:
What most likely happened is, something happened to the Time Capsule or its disk that damaged/corrupted everything -- your backups and other data.
How old is it? They don't last forever; most seem to run well for 3-4 years, but some fail earlier, others live longer.
Do you have power failures? If so, those are murder on electronics. Consider getting a small U.P.S. system for your Time Capsule (and modem, etc., as appropriate). -
My 2 TB Time Capsule’s memory is full because it will notautomatically delete old files as it is supposed to, so it is giving me zerobackup of my two computers now. How can this be fixed so my Time Capsule deletes the old data and savesthe new?
Neither my local computer consultant nor I have been ableto change any of the settings in Time Machine to correct this problem. Working with the choices in the TimeMachine, there does not appear that there is any way to change the frequency ofthe backups either, so, after a year has elapsed, the time capsule is full, andmy only choice appears to be to erase all the current data on the Time Capsuleand start over, something that I do not want to at all let alone repeat on anannual basis. My questions are:
What can be done to have my Time Capsule delete old filesas it is supposed to do, so it has memory available to allow my computers toback up?
Is this a software problem that can be fixed online or isdoes this require a mechanical fix of defective hardware?How much data is being backed-up from each Mac? (see what's shown for Estimated size of full backup under the exclusions box in Time Machine Prefs > Options).
Is there any other data on your Time Capsule, besides the backups?
Most likely, there just isn't room. Time Machine may be trying to do a very large (or full) backup of one or both Macs, and can't. Since it won't ever delete the most recent backup, there has to be enough room for one full backup plus whatever it's trying to back up now, plus 20% (for workspace).
