Limitation on the size of playlists within a tab?

Is there a limit on the number of files you have have within a specific tab's playlist? I've gotten a request for a project that would put about 500-550 small audio files into a playlist, but I'm not sure if iTunes U will let a list get that big.
We could break the playlist into smaller chunks, for this particular project, we'd rather not do that if we don't have to.

Ken,
The biggest I've ever seen is this:

161 items in a playlist.

Is there a limitation on the Size of Attachments to SBO Documents?

Hi, Experts.
Is there a size limitation to the Attachments that you can Attatch to an SBO Document like an Activity?
Does this depend only on the Hardware Specifications, or does SBO also limit the Size of Attachments?
Any help would be appreciated.
Thanks,
Marli

Hi Marli,
There is no limitation on the size of attachment. Otherwise also, SBO stores only the name of the file and copies it to the attachment folder. Since, in SBO, only the name is stored, therefore the size of the attachment does not matter.

How to reduce the size of PlayList display slightly?

I just want to see the selections at the very bottom which are cut off.

Nope. I want to reduce the SIZE of the screen, because the very bottom is off the big screen and I can't scroll down to it! I want to get the curser under the right lower corner to raise it, but I can't.

Limiting/controllong the size of the attachments

Hi,
I have developed a PDF form(which contains a SUBMIT button), and an application that processes it. As the PDF may contain files attached, the problem I face is: is there a way to limit or control the size of the complete PDF(including the attached files) that the user tries to send?
I imagine it exits, but I'm not able to find it.
Thanks in advance for your help.

My research shows that there is no way to limit the size of attachments to a PDF. I suggest you enter it as an emhancement.

How to list the active Alerts used within a tab(report) within a Document

Hello
We have a number of tabs/reports within a single webi document. There are a couple of alerts within the webi document but only one is used within a given tab/report.
Is there an API around that will help me query the alerts that are enabled within each tab/report within a given document instance?
There is an IReportProcessingInfo class that is around for it looks like its not applicable for Webi documents.

Hi Madhu,
Below is a sample code to traverse through the ReportStructure and get the Alerters from the cells.
Hope this helps.

How to change the size of playlist icons

I find the bigger sized icons for playlists in iOS 7.0.3 to be way too big-this causes lots of wasted space and is impossible to see all your playlists at one time. Is there any way for me to resize them?

Click on the Finder/Desktop
From the View menu > Show View options.
This is as large as they go
If your having trouble seeing when web browsing I have a alternative for that.
Firefox + NoSquint + Theme Font & Size Changer

How do I increase the size of icons within Word and other apps on my MacBook Pro

Trouble reading icons on top of menu bars etc...ie Microsoft Word and even Apple software. How can I get the text larger over all on my 15" MacBook Pro?
?

The icons in the menu bar and text can be increased by using a different display ratio. System Preferences>Displays. Try 1344x840 or 1280x800.

What are the size limitations, if any? Best practices?

Are there any limitations on the size of the Spiceworks database (including knowledge base), outside of the system it lives on, or a point at which it might begin to affect performance? If so, is there an archive feature, or is the solution deleting old tickets and kb articles?
This topic first appeared in the Spiceworks Community

Hi Astrid,
Thanks for reaching out.It could be a out of memory issue.
If you increase the memory that SAP Predictive Analysis is allowed to consume.
Go to the location where SAP Predictive Analysis was installed. In my case it is:
C:\Program Files\SAP Predictive Analysis\Desktop
Here you find a file "SAPPredictiveAnalysis.ini" - open this in Notepad and change the
"-Xmx" parameter to approximately half of our PC/laptops memory.
For instance in your case you could try with: -Xmx4096m
I have outlined this is a few more steps here:

What are the size limitations in Predictive Analytics - regression charts

I'm trying to display the trend chart for an Exponenential Regression Prediction and I got the following error. The Regression itself runs OK and provides a summary, but I can't display the data on a chart.
There's only 1 other related posting- Error PAS10066 and it doesn't provide much more info than is in the error itself.
Does anyone have extra info on what the size of the limitation is? Is it something that can be overcome with extra RAM etc?
I'm using the desktop version of PA 1.19, and I'm on a 64 bit installation of Windows 7 with 8GB of RAM, processing a csv file with 1.1 million rows.
I've used some filters in the Prediuct workflow to cut down on the amount of data being processed, and I got past the PAS10066 error and am now getting a max call stack size error - can't find anything related on SCN for this one.
Many Thanks
Astrid
