XML INVOICE Report RAXINV, Taxline is repeating for each invoice line
Hi Tim
Thanks a lot for your blog
Greeting !!
I have successfully created XML report for AR invoice Printing learning from your blog but stuck to a problem , whenever Invoice is having multiple lines ,say 20, then for each invoice line there is tax line printing 20 times like this:
PART NO.| CUSTOMER PART#/DESCRIPTION | UNIT PRICE | QUNTITY|
A123 | 34 WELD-ROD | 52 | 22 |
Tax Exempt @ 0.00
A234 | 238-AL WIER | 63 | 55 |
Tax Exempt @ 0.00
........ Assume there are 20 lines then tax line also repeating 20 times which i don't want .It should get printed only once if it is same
pls help me to achieve this
Thanks
RahulThanks Tim for Your Instant reply.
I have gone through your duplicate line elimination but my requirement is not this
I'll explain it, I am using LINE_DESCRIPTION tag for printing item description and this tag have two value for it, when the LINE_TYPE =LINE then LINE_DESCRIPTION tag is printing the line description and if LINE_TYPE =TAX
then LINE_DESCRIPTION tag is printing the taxline information. Now if I have 20 lines in Invoice then the tax line will also repeat for 20 times, and if i use duplicate line elimination logic and I have same item it'll not print that item, some times whole invoice become blank.
So I want to print 20 lines and out of that 15 lines are have same tax rate then it should print once at the end of 15th line and for remaining 5 lines if tax rate is different for each line then it should print at the end of each line (5lines)
In the linetreevariable i used <xsl:variable xdofo:ctx="incontext" name="invLines" select=".//G_LINES [LINE_TYPE!='FREIGHT']"/> i.e. I want only line type=LINE and TAX
Thanks

How can I open another iCloud account for each devices with the same apple id
my family has 2 iPhones 1 iPad 1 Macbook and 1 iMac. I had all the devices set up with one iCloud under 1 Apple ID. Now things are getting so mixed up with pictures, videos, calendar, notes and reminders etc. 1 iPhone is also unable to sync due to not having enough storage for all our devices. Someone from Genius Bar said we can have iCloud for each device under 1 Apple ID. I backed up all pics. videos notes important docs to my iMac and MacBook then I turned off all iCloud in all of the devices now I need help to create a new iCloud account at least for my 3 mobile devices to end all the confusion. every time I try to click the button "set up iCloud on this device" I always go back to apple site with step by step by step instruction but I keep going around in a loop. Please help
I'm not sure what they told your at the Apple store, but each Apple ID can only create a single iCloud account. If you want separate accounts for all these devices, they will have to be created using separate IDs. Note: you can do this and still share the same ID for other services such as your iTunes store account. The iCloud ID does not need to be the same as the ID used for other services.
To create an account, go to Settings>iCloud and sign in with a different Apple ID. If you want to migrate a copy of the current iCloud data to the different accounts, start by saving any photo stream photos that you want to keep to your camera roll (unless already there) by opening your my photo stream album, tapping Select, tapping the photos, tap the share icon (box with upward facing arrow), then tapping Save to Camera Roll. If you are syncing notes with iCloud that you want to keep, you'll need to open each of your notes and email them to yourself so you can later copy and paste the text into new notes created in your new account. Then go to Settings>iCloud, tap Delete Account (which only deletes it from this device, not from iCloud; the devices keeping the current account will not be effected by this), provide the password to turn off Find My iDevice and choose Keep on My iDevice when prompted. Then sign back in with a different Apple ID to create your new account and choose Merge to upload your data. -
I have been using one apple ID for 4 family members. Up until now it hasn't been a problem but now that we all have our own devices how do I create new apple ID's for each of us and them move the approprioate things from the original apple ID account to the new ones for each of us?

Thanks Csound1, wish I have seperated everything from the beginning but when your kids are little and start buying music etc it just didn't seem like an issue.
That has a familiar ring to it -
Hello,
Between my family, we have 2 iPhones, multiple computers, iPads, and an Apple TV ALL tied in to the same Apple ID (the one I created when I got my first device). With iCloud coming, I wanted to know if I need to create separate Apple IDs for each family member (for emails, contacts, calendars, etc.). For instance, I would like to share certain contacts and a calendar with only my wife, all media between all family members, and have home sharing so that I can play/stream content on my Apple TV. Will there be a way to have multiple and distinct me.com accounts and yet share the same Apple ID?
Apologies for being verbose — just wanted to give ample info/background.
Thanks,
Jay.I happened to stop at the Apple store yesterday for a separate issue and had a discussion about iCloud. Seems like this is how iCloud works (also, there's another thread on this forum that explains it well).
Each member of the family can have their own iCloud ID, which will be used for Mail, Calendar, Contacts, Apps, Bookmarks, Media, Photos, etc. and having this content synced automatically with a Mac (computer). The iCloud IDs work in tandem with the associated Apple ID — so while you cannot have multiple Apple IDs, you can certainly have multiple iCloud IDs tagged with a certain Apple ID.
While all this makes sense from the iOS device standpoint, I'm unclear on how things will sync with a Mac computer, especially if the family uses a single iMac with multiple login IDs for various members. For instance, I currently have an iMac and iTunes content resides in my Public folder, which my wife can still access when she logs in with her login ID. I'm guessing that I'll be able to set up her iCloud ID using her login, set up my iCloud ID using my login, while both our iMac logins will retain the same Apple ID. This would take care of syncing Photos, Contacts, Calendars, etc.
Another (not sure if unique) problem I face is our Address Book — right now, we have one GIANT address book with different groups set up. Certain groups sync to her iPhone, while others to mine. Some contacts are common between both of us. I'm hoping that if she/I updates a common contact, then the change will be reflected in both our groups of contacts. I hope this makes sense — for instance, I update a contact named Joe, and he's on my group of contacts in my iPhone. Hope iCloud updates the master contact card for Joe on the iMac, which would then automatically trigger the update on my wife's group of contacts—that Joe also belongs to— leading to an update on her iOS device as well.
Apologies for the lengthy response.. -
How to create one primary key for each vendor
Hi all
i am doing IDOC to jdbc scenario
i am triggering idoc from R/3 and the data is going into DB table vendor through XI.
structures are as follows:
sender side: ZVendorIdoc (this is a customized IDOC , if i triger IDOC for multiple vendors then it triggers only 1 idoc with multiple segment )
Receiver side:
DT_testVendor
Table
tblVendor
action UPDATE_INSERT
access 1:unbounded
cVendorName 1
cVendorCode 1
fromdate 1
todate 1
Key1
cVendorName 1
if i trigger idoc for multiple vendors ,for example vendor 2005,2006 and 2010 . then i can see that the only key comes from the very first field (2005) and the whole record for vendor 2005,2006 and 2010 goes into the table with this(2005) as a primary key
now again if i send data for these three vendor 2005, 2006 , 2010, in which record for the vendor 2005 is same and for 2006 and 2010 are different than it takes 2005 as a primary key and it does not update the data in the table.
my requirement is like this: for each vendor there should be one unique key assigned.
for above said example there should come three keys one for each vendor .
could you please help me how to do this???????????Hi,
In Mapping Make the statement is 0-unbounded.For each vendor create a statement.This will solve your problem.

If you registrate one Apple ID for each iPhone/iPad, you'll get 5GB on iCloud for each Apple ID, right? I have two iPhones and one iPad with the same Apple ID, why can't I get 5 GB fo each of them?
Actually, everyone missed one point, when a device is priced, the cost of icloud storage space for that device is also included in it that is why they are able to give you 5gb each for each user ID, in nutshell there is nothing free coming with apple device purchase, it is paid for. What they are trying by giving only 5gb per user ID irrespective of the number of devices used is pure broadlight looting, they take money from you when you buy each device and give you nothing, This is a case of goods and services bought but not fully deliverd ie apple can be suied for discreminatory treatment towards it's users. I wonder why no one tried this yet in America where everyone sue everyone for petty things..... there is no one to take up this issue? . if tim got any love for the guys who shell out money for the devices his company makes, he should be implimenting this as priority before someone wake up from sleep and sue him.
-
We have several apple products in the family. I would like to set up different icloud accounts for each memeber. I lately noticed having activated different devices with same icloud account that each device can access everyones messages by going in their settings and clicking which number or email they want to use to see messages. Let me make sure I am understood, on my sons ipod in his messages settings he can switch to my cell number and see all my messages. Re setting the devices isn't my great issue but can i set up each kids user account on my mac to their individual icloud accounts?
Thanks!Any devices connected to the same icloud account can sync all the data on that account. For this reason an icloud account is really for a single user.
On a mac, if each user has their own account, then the itunes for that mac account should be set up to connect to that user's icloud account (System preferences>icloud). -
I have multiple devices in my family. Each of us has an iPhone and an iPad. Is there a way for each of us to have our own Apple ID but one account so we can all get the same music, movies, books, etc. I can't see paying twice for something in the same family.
Welcome to the world of digital media. Your can't really transfer it. I don't know what the rules are about transferring to your spouse but I do know that in some cases when you die, your heirs cannot inherit your digital media. This is why there is still an advantage to buying the CD since the usage rights belong to whomever holds the physical media.
A possible workaround is to burn the songs to a music CD with yout account (tracks only without song titles) and then having your wife upload it as a regular music CD onto her account. It's been a while since i've done this so I'm not sure if it would work now.
Please note that I'm not advocating copyright and/or TOS violations. I'm only suggesting ways to copy music for your own personal use which has traditonally been permitted. I only did this because I wanted to convert iTunes songs to mp3 files so I could burn them onto a data CD for use in my car. It would make sense that since married couples are a joint entity, this would be personal use.
Also, I'm not a lawyer so don't take this as legal advice. -
Creating view to get first row for each table !!
I am having tables(more than 10) which are related using foreign key and primary key relationship.
Example:
Table1:
T1Prim T1Col1 T1Col2
Table2
T2For T2Prim T2Col1 T2Col2 T2Col3
(here T2For will have value same as T1Prim and in my design it has same column name i.e. T1Prim)
Table3
T3For T3Prim T3Col1 T3Col2 T3Col3
(here T3For will have value same as T2Prim)
and so on.
The data in the tables is like For table1 there will be one record, for table2 there will be one record and for table 3 there are more than one records.
Can i view either the first record for each of them or all records from each of them by writing the following view.
I have written a view like this:
Create or replace view test (T1Prim,T1Col1, T1Col2,T2Prim,T2Col1 T2Col2, T2Col3, T3Prim,T3Col1, T3Col2, T3Col3)
As
Select
Table1.T1Prim,
Table1.T1Col1,
Table1.T1Col2,
Table2.T2Prim,
Table2.T2Col1,
Table2.T2Col2,
Table2.T2Col3,
Table3.T3Prim,
Table3.T3Col1,
Table3.T3Col2,
Table3.T3Col3
From
Table1,
Table2,
Table3
where
Table1.Prim = Table2.For
and Table2.Prim = Table3.For
When i ran the select statement on the view I am not getting any data. Whereas there is data when select is ran on individual table.
Can someone please tell me where i am goofing.
Thanks in the anticipation that i will get some hint to solve this.
Eagerly waiting for reply.
Thanks !!I mean use a collection :
Collection Methods
A collection method is a built-in function or procedure that operates on collections and is called using dot notation. The methods EXISTS, COUNT, LIMIT, FIRST, LAST, PRIOR, NEXT, EXTEND, TRIM, and DELETE help generalize code, make collections easier to use, and make your applications easier to maintain.
EXISTS, COUNT, LIMIT, FIRST, LAST, PRIOR, and NEXT are functions, which appear as part of an expression. EXTEND, TRIM, and DELETE are procedures, which appear as a statement. EXISTS, PRIOR, NEXT, TRIM, EXTEND, and DELETE take integer parameters. EXISTS, PRIOR, NEXT, and DELETE can also take VARCHAR2 parameters for associative arrays with string keys. EXTEND and TRIM cannot be used with index-by tables.
For more information, see "Using Collection Methods".
Syntax
Text description of the illustration collection_method_call.gif
Keyword and Parameter Description
collection_name
This identifies an index-by table, nested table, or varray previously declared within the current scope.
COUNT
COUNT returns the number of elements that a collection currently contains, which is useful because the current size of a collection is not always known. You can use COUNT wherever an integer expression is allowed.
For varrays, COUNT always equals LAST. For nested tables, normally, COUNT equals LAST. But, if you delete elements from the middle of a nested table, COUNT is smaller than LAST.
DELETE
This procedure has three forms. DELETE removes all elements from a collection. DELETE(n) removes the nth element from an index-by table or nested table. If n is null, DELETE(n) does nothing. DELETE(m,n) removes all elements in the range m..n from an index-by table or nested table. If m is larger than n or if m or n is null, DELETE(m,n) does nothing.
EXISTS
EXISTS(n) returns TRUE if the nth element in a collection exists. Otherwise, EXISTS(n) returns FALSE. Mainly, you use EXISTS with DELETE to maintain sparse nested tables. You can also use EXISTS to avoid raising an exception when you reference a nonexistent element. When passed an out-of-range subscript, EXISTS returns FALSE instead of raising SUBSCRIPT_OUTSIDE_LIMIT.
EXTEND
This procedure has three forms. EXTEND appends one null element to a collection. EXTEND(n) appends n null elements to a collection. EXTEND(n,i) appends n copies of the ith element to a collection. EXTEND operates on the internal size of a collection. So, if EXTEND encounters deleted elements, it includes them in its tally. You cannot use EXTEND with index-by tables.
FIRST, LAST
FIRST and LAST return the first and last (smallest and largest) subscript values in a collection. The subscript values are usually integers, but can also be strings for associative arrays. If the collection is empty, FIRST and LAST return NULL. If the collection contains only one element, FIRST and LAST return the same subscript value.
For varrays, FIRST always returns 1 and LAST always equals COUNT. For nested tables, normally, LAST equals COUNT. But, if you delete elements from the middle of a nested table, LAST is larger than COUNT.
index
This is an expression that must yield (or convert implicitly to) an integer in most cases, or a string for an associative array declared with string keys.
LIMIT
For nested tables, which have no maximum size, LIMIT returns NULL. For varrays, LIMIT returns the maximum number of elements that a varray can contain (which you must specify in its type definition).
NEXT, PRIOR
PRIOR(n) returns the subscript that precedes index n in a collection. NEXT(n) returns the subscript that succeeds index n. If n has no predecessor, PRIOR(n) returns NULL. Likewise, if n has no successor, NEXT(n) returns NULL.
TRIM
This procedure has two forms. TRIM removes one element from the end of a collection. TRIM(n) removes n elements from the end of a collection. If n is greater than COUNT, TRIM(n) raises SUBSCRIPT_BEYOND_COUNT. You cannot use TRIM with index-by tables.
TRIM operates on the internal size of a collection. So, if TRIM encounters deleted elements, it includes them in its tally.
Usage Notes
You cannot use collection methods in a SQL statement. If you try, you get a compilation error.
Only EXISTS can be applied to atomically null collections. If you apply another method to such collections, PL/SQL raises COLLECTION_IS_NULL.
You can use PRIOR or NEXT to traverse collections indexed by any series of subscripts. For example, you can use PRIOR or NEXT to traverse a nested table from which some elements have been deleted.
EXTEND operates on the internal size of a collection, which includes deleted elements. You cannot use EXTEND to initialize an atomically null collection. Also, if you impose the NOT NULL constraint on a TABLE or VARRAY type, you cannot apply the first two forms of EXTEND to collections of that type.
If an element to be deleted does not exist, DELETE simply skips it; no exception is raised. Varrays are dense, so you cannot delete their individual elements.
PL/SQL keeps placeholders for deleted elements. So, you can replace a deleted element simply by assigning it a new value. However, PL/SQL does not keep placeholders for trimmed elements.
The amount of memory allocated to a nested table can increase or decrease dynamically. As you delete elements, memory is freed page by page. If you delete the entire table, all the memory is freed.
In general, do not depend on the interaction between TRIM and DELETE. It is better to treat nested tables like fixed-size arrays and use only DELETE, or to treat them like stacks and use only TRIM and EXTEND.
Within a subprogram, a collection parameter assumes the properties of the argument bound to it. So, you can apply methods FIRST, LAST, COUNT, and so on to such parameters. For varray parameters, the value of LIMIT is always derived from the parameter type definition, regardless of the parameter mode.
Examples
In the following example, you use NEXT to traverse a nested table from which some elements have been deleted:
i := courses.FIRST; -- get subscript of first element
WHILE i IS NOT NULL LOOP
-- do something with courses(i)
i := courses.NEXT(i); -- get subscript of next element
END LOOP;
In the following example, PL/SQL executes the assignment statement only if element i exists:
IF courses.EXISTS(i) THEN
courses(i) := new_course;
END IF;
The next example shows that you can use FIRST and LAST to specify the lower and upper bounds of a loop range provided each element in that range exists:
FOR i IN courses.FIRST..courses.LAST LOOP ...
In the following example, you delete elements 2 through 5 from a nested table:
courses.DELETE(2, 5);
In the final example, you use LIMIT to determine if you can add 20 more elements to varray projects:
IF (projects.COUNT + 20) < projects.LIMIT THEN
-- add 20 more elements

Hi there,
I am a beginner in Visual Basic Express 2010. I have a Point of Sale program that uses DataGridView to display records from an external microsoft access
database using the fillby query.
It works, but it repopulates the same row each time, but i want to be able to display multiple records at the same time, a new row should be filled for
each click of the fillby button.
also I want to be able to delete any records if the customer suddenly decides to not buy an item after it has already been entered.
so actually 2 questions here:
1. how to populate a new row for each click of the fillby button
2. how to delete records from data grid view after an item has been entered
Thanks
VishwasHello,
The FillBy method loads data according to what the results are from the SELECT statement, so if there is one row then you get one row in the DataGridView, have two rows then two rows show up.
Some examples
Form load populates our dataset with all data as it was defined with a plain SELECT statement. Button1 loads via a query I created after the fact to filter on a column, the next button adds a new row to the existing data. When adding a new row it is appended
to the current data displayed and the primary key is a negative value but the new key is shown after pressing the save button on the BindingNavigator or there are other ways to get the new key by manually adding the row to the backend table bypassing the Adapter.
The following article with code shows this but does not address adapters.
Conceptually speaking the code in the second code block shows how to get the new key
Public Class Form1
Private Sub StudentsBindingNavigatorSaveItem_Click(
sender As Object, e As EventArgs) Handles StudentsBindingNavigatorSaveItem.Click
Me.Validate()
Me.StudentsBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.MyDataSet)
End Sub
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'MyDataSet.Students' table. You can move, or remove it, as needed.
Me.StudentsTableAdapter.Fill(Me.MyDataSet.Students)
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Me.StudentsTableAdapter.FillBy(Me.MyDataSet.Students, ComboBox1.Text)
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Me.MyDataSet.Students.AddStudentsRow("Jane", "Adams", "Female")
End Sub
End Class
Get new key taken from
this article.
Public Function AddNewRow(ByVal sender As Customer, ByRef Identfier As Integer) As Boolean
Dim Success As Boolean = True
Try
Using cn As New OleDb.OleDbConnection With {.ConnectionString = Builder.ConnectionString}
Using cmd As New OleDb.OleDbCommand With {.Connection = cn}
cmd.CommandText = InsertStatement
cmd.Parameters.AddWithValue("@CompanyName", sender.CompanyName)
cmd.Parameters.AddWithValue("@ContactName", sender.ContactName)
cmd.Parameters.AddWithValue("@ContactTitle", sender.ContactTitle)
cn.Open()
cmd.ExecuteNonQuery()
cmd.CommandText = "Select @@Identity"
Identfier = CInt(cmd.ExecuteScalar)
End Using
End Using
Catch ex As Exception
Success = False
End Try
Return Success
End Function
In closing I have not given you a solution but hopefully given you some stuff/logic to assist with this issue, if not perhaps I missed what you want conceptually speaking.

Is there a for-each statement in XSQL like the one in XSL?
I'm trying to do the following:
<?xml version="1.0" ?>

</allusers>
</database>Now as you can see, I have 4 instances of <checkboxuser> in my XSQL page. These values are being passed in from checkboxes on the previous page. Is there an XSQL command that will say something like <xsql:for-each select="/database/request/parameters/checkboxuser"> ?
So that it'd look something like this in the original code:
<?xml version="1.0"?>
<!--<?xml-stylesheet type="text/xsl" href="/dvd/xsl/admin/listuser.xsl"?>-->
<database connection="dvddb" xmlns:xsql="urn:oracle-xsql">

<xsql:query id-attribute="" tag-case="lower" rowset-element="allusers" row-element="userinfo">
SELECT FIRSTNAME AS "FIRST-NAME",
LASTNAME AS "LAST-NAME",
EMAIL AS "EMAIL",
USERNAME AS "USER-NAME",
PASSWORD AS "PASSWORD",
ACCESSLEVEL AS "ACCESS-LEVEL"
FROM LKUP_USER
WHERE USERNAME = '<xsql:for-each select="/database/request/parameters/checkboxuser">'
ORDER BY ACCESSLEVEL
</xsql:query>
</database>Or something like that... The XSL works fine, but not when I want to pull info from the DB.. :)

can any one help me on what kind of indexes do i have to create?
1. one index for each column used in "where clause"
2. one index for 8 columns and some other indexes for other used columns
3. one index for all columns
or something else etc...

Let me suppose that you are runing OLTP database and you have a where clause with 8 columns.
1) are all those where clause equalities (where col1 = and col2 =) or there are inequalities?
2) could you evaluate the most repetitive columns?
3) could you know the column that could have the best clustering factor (the column which most follow a certain order in the table)
Based on that I would suggest to create one b-tree index having 8 columns (even though that it seems for me to high) this index should follow the following points:
1) put the most repetitive column at the leading edge (and compress the index if necessary)
2) put the columns that are used in equalitity predicate first
3) put the column having the best clustering factor first
The most precise index you have the best access you could gain.
Of course that you have to know that an index access is not always good and a FULL table scan is not always bad.

Using an IF Statement in Numbers on Entire Column for Each Value that is True
Hi,
I am trying to create a formula to help calculate a chart chart.
I need to gather the SUM of Column A for Each instance that Column B of the same row is =TRUE. I need to do it in the most general way possible as this formula will be gathering information from multiple tables and creating a sum.
For Instance:
TABLE 1
Column A
Column B
5
True
3
False
4
True
1
False
TABLE 2
Column A
Column B
5
True
3
False
4
True
1
False
The result I am looking for would be 18.
Thanks for any input.JE,
Here's an expression that you could use:
=SUM(SUMIF(Table 1 :: B:B, TRUE, Table 1 :: A:A), SUMIF(Table 2 :: B:B, TRUE, Table 2 :: A:A), and so forth for additional tables)

Using If condition in For EACH Group
Hi all,
I want to use if condition in for-each-group. Basically my requirement is that i want to use dynamic grouping. There will be two groups and the upper group and lower group will be selected on the basis of a report parameter.
I hope i made it clear enough. So please help me in this. Any ideas will be highly appreciable.
Thanks and regards
NaveedYou can add a If condition filed after the for-each field
for EG : <?if:ADDRESS_TYPE = 'Employee Address'?>
and then add anothet field which has <?end if?>
Hope this helps.
Thanks,
