Exclude duplicate or overlapping data when adding time fields

Post Author: Mark O
CA Forum: Formula
I am using Crytsal Reports XI. I have a several rows of start times, end times and total minutes. I would like to get a total time but some of the times are duplicates or overlapping each other. These duplicates/overlaps are not errors; they need to be in the report. I just can't double count the time. I am seeking a result of 45 Total Min in the below example. Thanks.

I'm not sure if your example is misleading!
For what you've shown a simple calculation between the start time of the first record and the end time of the last record gives your answer (assuming an ascending sort on start time, end time). However, this might just be because there's always an overlap in your example data.
Another solution might be to compare the start time of each record with the end time of the previous record, and choose the appropriate one of these as a new 'start time' for each record. But this might just be because the end times in your example data are always >= the end time of the previous record.
Is the following example possible? Would you want the final answer to be 50?

Not able to see Metadata fields when adding the fields to the rule in UCM

Not able to see Metadata fields when adding the fields to the rule even after creating them in information fields of configuration manager.It is happening for few fields only.We are using 10.1.3 version of UCM.Kindly provide a solution if any.

Dhilipan,
I am trying to setup AES at the current Customer.
You are right on LR_JP to be linked to customs code list instead of ACE and I do achieve that if I were to maintain the Custom code list by maintaining the assignment for EAR in a separate test.
I was infact trying to follow the link: http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/30c7015e-c191-2d10-71b9-95907dc8edd1?overridelayout=t…
On this document, if you look at page# 14 thru 17, it has the steps I described in my original note with customs code still appearing in the drop down for 'EXCPT' for EAR.
Nevertheless, I wanted to default Type = C50 when the license type for the line on the Customs declaration is 'EXCPT' but if you see the very last screen-shot below, even though the license type configuration has default value as 'C50' it did not get pulled into the line item Documents tab when I tried to pick the category as 'CUII'.
Let me know your thoughts on defaulting the data into Customs declaration for AES filing.
What I want to achieve is the following:
When License type is 'EXCPT', system should default the type as 'C50'
Should put the License type 'EXCPT' into the number field
Should put the actual License# 'ENC' into the Supplement field
Should put the ECCN # '5A002' into the Details field

Missing birth date when adding apple-id for child

When adding apple-id for child the field for adding birth date is missing in form.

If they are 13 they would obtain a normal Apple ID (13 is the age cutoff historically for an Apple ID). They should create one normally and then you can associate it with your account. I don't know if purchase control will work with that.

Trigger a Signature Date when Digital Signature Field is Signed

I'm looking for a way to have a date field populate when a digital signature field is signed on my Adobe Designer Form. The signature technology I'm using does not work seamlessly with Adobe LiveCycle Designer and is unable to add the date when the document is signed. So I was thinking I could call a function to add the date to the date field when the signature field is signed. I just dont know how to do it.
Please help!
Thanks!

Here is some code that will allow you to check the signature field:
// check to see if Claimant signature field is signed.
var oSOM = claimsign.somExpression; // Returns the full SOM expression i.e. xfa[0].form[0].form1[0]...
var truncSOM = oSOM.substring(15); // Truncating 'xfa[0].form[0]' from SOM to get acroforms name of the field.
var oState = event.target.getField(truncSOM).signatureValidate(); // Get the current field's signed state
In this case the signature field is called claimsign. After running this code the variable oState will conatin a value ....if it is 0 then the field is not signed. So you can add code like this:
if (oState == 0 ) {
     // signature field is not signed
     app.alert("You must sign the form before submitting")
} else {
     //The signature field is signed
     go through your submission process code
Hope that helps

Form Validation using Javascript error when adding extra fields

Hi,
I have a form (with a few fields which require validation) which works just fine. I have added extra fields to the form and require them to validate too. My problem is that they are not showing via the behaviours/validation box and I can't figure out how to sort it! They are contained within the form element. I have tried to delate the original validation and start again but to no avail.
Please can someone help me?
Code below.
Many thanks
function MM_validateForm() { //v4.0
var i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
for (i=0; i<(args.length-2); i+=3) { test=args[i+2]; val=MM_findObj(args[i]);
    if (val) { nm=val.name; if ((val=val.value)!="") {
      if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
        if (p<1 || p==(val.length-1)) errors+='- '+nm+' must contain an e-mail address.\n';
      } else if (test!='R') { num = parseFloat(val);

Overlapping data when more data column chart SSRS

Hi guys,
In my ssrs report the column chart display is not good when more number of datas are viewed.How to overcum this issue
I searched more on this issue no good solution found.
I attached screenshot for this report,
any suggestions pls
Thanks,
R.B

Hi R.B,
I can reproduce the issue in my local environment. If there are more column data with adjacent values in the chart, the label will be overlapped due to the insufficient space. In this scenario, there are several properties you can use to try to get the labels
to fit better. Click the data point to open the Properties Windows, then go to the SmartLabels node.
Expand the "NoMoveDirections" node. This will give us a lot of directions that we can use to restrict the directions that the labels can move in. We can try to change directions to see if it helps.
Try to enlarge the chart size and use the method below to adjust the column size, it will free up more space to contain the label.
http://www.bidn.com/blogs/ChrisAlbrektson/bidn-blog/1832/ssrs-adjust-bar-chart-width
If we want to remove the black arrow, we can refer to the following thread:
http://social.technet.microsoft.com/Forums/en-US/e3019086-4f72-4898-ba86-2e7c97c8fae4/ssrs-series-lable-overlaping-issue?forum=sqlreportingservices
Alternatively, we can use Tooltip property to instead of actually displaying. Type the same expression with Value field in the Tooltip property.
Hope this helps.
Thanks,

How Can I Keep Photo Data When Adding Photo To New Book?

All of my photos in IPhoto have dates and descriptions as part of the file names. When I transfer then to make a book, all of this data goes away. Is there any way I can keep this data as a description of the photo.

Where are you transferring the file to and how? As long as you use iPhoto the title and description remain associated with the photos. Are you referring to the title and having the title show on the book's page along with the photo? There is just one theme that displays the title: Folio
The only way to get the description to display is to change the title to what you put in the Information/Description field. That can be done automatically with the Applescript described in my post here: http://discussions.apple.com/thread.jspa?messageID=5400478&#5400478
OT
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier versions) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. There are versions that are compatible with iPhoto 5, 6, 7 and 8 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
NOTE: The new rebuild option in iPhoto 09 (v. 8.0.2), Rebuild the iPhoto Library Database from automatic backup" makes this tip obsolete.

-5002 error ("No Data ") when adding record to a UserTable

B1 2007A
Here's my code. I've stripped it about as far as I could to try and solve this problem... but I must be missing something. Basically, I referenced the UIDIBasicApp for the UserTables portion.
In the "PopulateUserTable" subroutine, where I attempt to add the record with:
lngRetCode = objUserTable.Add()
... lngRetCode comes back as "-5002". The error message is "No Data ".
I've added records with the same data into the table through B1 User-Defined Windows and it accepts the data without a problem. I've been re-checking the code, and searching the forums and the help file since last week, and I haven't found any reference to a problem like this.
Any ideas? Thanks!

Duplicate Songs On iPod When Adding New Playlist?

Hi All-
I'm experiencing a new problem that is driving me crazy. It seems to have started after the last iPod updater but that could just be coincendence. Now, whenever I copy a playlist from iTunes to my video iPod, it will copy most of the song files as well (not all of them but a good portion) - making many duplicate song entries on my iPod that I then have to go in and delete?
Any ideas?

Settings for fios actiontec router using coax when adding time capsule as ac router

I would like to set up my new time capsule as my main wireless router on a fios coax-wan internet that is currently using the m1424wr revisiion I router.
What are the settings i should use for the actiontec versus the time capsule and what is the best way to set it up to take advantage of the AC wireless on the TC without losing set top box features providing by the actiontec router over coax?
I got the TC to conenct via WAN to LAN on actiontec but i think that may limit my ability to take advantage of the capabilities of the time capsule.
Any suggestions ont the best set up given I have multiple devices both iOS, OSX and need relaiable coverage of a 3 story town house.
Thanks!
Tim

Best setup is to bridge the TC.. which I think is how you set it up.
I got the TC to conenct via WAN to LAN on actiontec but i think that may limit my ability to take advantage of the capabilities of the time capsule.
You do miss the guest wireless network and BTMM on the TC itself... but otherwise it is the best for everything else.
Tell us if you need these functions.
To cover a 3 storey town house a single wireless router is not going to be adequate.. if you can place the TC on a different floor to the modem that could be very helpful, with ethernet to link the two.
Otherwise you need an Express or two so the coverage can be extended.

Reports Developer V9.0.2.0.3, problem when adding sum field

My report stops working as soon as I add a summary field to the first query. Not even using it yet, just adding it, and closing the report (.jsp) and then opening it again. I have been trying to debug this problem for a couple of days now. This is how I found out the problem occurs after adding the summary field.
I get the message "REP-0002 Unable to retrieve a string from the Report Builder message file."
Then, I look at the report. There is no layout, everything in the data model view is molded together. VERY STRANGE.

Try using .rdf rather than .jsp to save the report. This may get around your problem unless you're using the websource. You could also try saving to XML and make sure that loads/saves correctly.

DB Utility (SE14) when adding new fields on standard dictionary table

Hi all,
we're searching of an official SAP document (or OSS Note) that certifies the mandatory use of DB utility (SE14) when we add one or more custom fileds on an append structure of a standard table (i.e. like VBAP).
Note: The custom append Structure already exists.
Thanks in advance,

I have a list A with a calculated field named A.A. I have a list B that has a lookup field to list A, to field A.A, named B.A. I add the two lists in a wiki page and I try to connect them - I.E., select a row from A and the rows from B would be automatically
filtered.
The B\Connections\get filtered values from A and select Provider:A.A, Consumer B.A doesn't bring any results. If I do the exact opposite: A\Connections\get filtered values from B and select Provider:B.A, Consumer A.A works fine. But, this is not what
I want.
If the A.A isn't calculated field, everything works fine. So, it looks like there's an issue with calculated fields acting as consumers.
Is this a known issue and are there any know workarounds? A workaround is to abandon calculated field and use sharepoint designer workflow.
Thank you

Hi,
According to your post, my understanding is that you had issues about connecting web parts.
I try to reproduce the issue, however, everything works well.
Create a custom list named List A, add a caculated column named A.A(Formula: =Title).
Create a custom list named List B, add a lookup column named B.A(List A: A.A).
Create a page and then insert the two list view web parts.
Edit page, select List B->Connections->Get Filtered Values From List A.
Then I can filter the List B.
I recommend to create another caculated column and get filter value form it to check whether it works.
Best Regards,

Error when Time field is left empty

Hi:
Does anyone know the exact reason for the following error? When I leave the input field of type Time empty I get the below error. It seems to orginate when the time field is being set internally by web dynpro. Thanks for your help.

Subramania,
Strange that this error occurs at all: seems that you first type value on UI, left field, return back to field and then clear value... So there is "change event" at server.
Anyway, check your RFC module -- probably this is mandatory parameter and you may not left it blank. Also check whether some default value can be used.
