Get sample row for each recrd.
I have a table EMP
having columns as as
GROUP , GROUP_NAME, EMPNO , EMP_NAME
Having following data

XML DB: is it possible to get a row for each element in a container element?
I have an XML document containing a container element (collection). If I query, using an XPath expression, the contained elements I get a row for each container element with the contained element concatenated. Is it possible to get a row for each contained element?
I run this simple query:
select extract(xmltype('<colors><color>Red</color><color>Green</color></colors>')
, '/colors/color/text()').getstringval() from dual
And get this result:
EXTRACT(XMLTYPE('<COLORS><COLOR>RED</COLOR><COLOR>GREEN</COLOR></COLORS>'),'/COL
RedGreen
1 row selected.
What I would like to have is:
Red
Green
2 rows selected.
Wishful thinking or possible? Many thanks!Sure. This is where our XMLSequence() function comes in. It allows you to treat the top-level nodes in a nodeset as if they were rows in a table when combined with the TABLE() operator. Here's an example.
First, to make the SQL look a little cleaner, I like to define a function like this:
create or replace function testdoc return xmltype as
begin
return xmltype('<colors><color>Red</color><color>Green</color></colors>');
end;.
To break out the nodeset of <color> elements as a table, we use the following query:
select value(list_of_color_elements).extract('*/text()').getStringVal() as color
from TABLE( XMLSequence( extract(testdoc(),'/colors/color'))) list_of_color_elements.
Or, using the new-in-9.2 extractValue() operator so we don't have to remember the text() part:
select extractValue( value(list_of_color_elements), '.') as color
from TABLE( XMLSequence( extract( testdoc() ,'/colors/color'))) list_of_color_elements.
Here the TABLE(XMLSequence(...)) combo produces a table of XMLType, with one XMLType object in each row of the table.
In general, if the XMLType instance were coming from an XMLType table xmltab the query would look like this:
select extractValue( value(colors), '.') as color
from xmltab x, /* Important that this table comes earlier in the FROM clause! */
TABLE( XMLSequence( extract( value(x),'/colors/color'))) colors.
And if the XMLType were instead in a column of XMLType named doc in a table xmltab, then we would have the syntax:
select extractValue( value(colors), '.') as color
from xmltab x, /* Important that this table comes earlier in the FROM clause! */
TABLE( XMLSequence( extract( x.doc ,'/colors/color'))) colorsOnce you get the hang of it, you'll see that the combination of TABLE(XMLSequence()) to "shred" XML nodes into rows, and XMLAgg() to aggregate fragments of XML across multiple rows back into a single document, is quite powerful. -
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

I'm trying to get the count for each row to total count for each month
Something like this
Hardware | Jan
Monitors | 5
Processors | 137
Printers | 57
etc........
How can I write a query for this. I can get the Hardware column but don't know how to get the next column.If you can provide more data like sample input DML statements it would have been wonderful..
Assuming is , you need a pivot. Here is an article on basic Pivot..
http://sqlsaga.com/sql-server/how-to-use-pivot-to-transform-rows-into-columns-in-sql-server/
something like this may be..
DECLARE @Input TABLE
Hardware VARCHAR(20),
[Date] VARCHAR(20)
INSERT INTO @Input VALUES('Monitor', '01/01/2014'), ('CPU', '01/01/2014'), ('Monitor', '01/03/2014')
, ('ABC', '01/01/2014'),('Monitor', '02/01/2014')
;WITH CTE AS
SELECT Hardware, LEFT(DATENAME(M, [Date]),3) AS [MonthName] FROM @Input
SELECT *
FROM
SELECT Hardware, [MonthName], COUNT(Hardware) AS Count FROM CTE GROUP BY Hardware, [MonthName]) a
PIVOT (MAX([Count]) FOR [MonthName] IN ([Jan], [Feb])) pvt
Please mark as answer, if this has helped you solve the issue.

Getting the first row for each group
Hi Everyone,
I have a query which returns a number of rows, all of which are valid. What I need to do is to get the first row for each group and work with those records.
For example ...
client flight startairport destairport stops
A fl123 LGW BKK 2
A fl124 LHR BKK 5
B fl432 LGW XYZ 7
B fl432 MAN ABC 8
.... etc.
I would need to return one row for Client A and one row for Client B (etc.) but find that I can't use the MIN function because it would return the MIN value for each column (i.e. mix up the rows). I also can use the rownum=1 because this would only return one row rather than one row per group (i.e. per client).
I have been investigating and most postings seem to say that it needs a second query to look up the first row for each grouping. This is a solution which would not really be practical because my query is already quite complex and incorporating duplicate subqueries would just make the whole thing much to cumbersome.
So what I really new is a "MIN by group" or a "TOP by group" or a "ROWNUM=1 by group" function.
Can anyone help me with this? I'm sure that there must be a command to handle this.
Regards and any thanks,
Alan Searle
Cologne, GermanySomething like this:
select *
from (
select table1.*
row_number() over (partition by col1, col2 order by col3, col4) rn
from table1
where rn = 1In the "partition by" clause you place what you normally would "group by".
In the "order by" clause you define which will have row_number = 1.
Edit:
PS. The [url http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/functions004.htm#i81407]docs have more examples on using analytical functions ;-)

How to Get Missing Dates for Each Support Ticket In My Query?
Hello -
I'm really baffled as to how to get missing dates for each support ticket in my query. I did a search for this and found several CTE's however they only provide ways to find missing dates in a date table rather than missing dates for another column
in a table. Let me explain a bit further here -
I have a query which has a list of support tickets for the month of January. Each support ticket is supposed to be updated daily by a support rep, however that isn't happening so the business wants to know for each ticket which dates have NOT been
updated. So, for example, I might have support ticket 44BS which was updated on 2014-01-01, 2014-01-05, 2014-01-07. Each time the ticket is updated a new row is inserted into the table. I need a query which will return the missing dates per
each support ticket.
I should also add that I DO NOT have any sort of admin nor write permissions to the database...none at all. My team has tried and they won't give 'em. So proposing a function or storable solution will not work. I'm stuck with doing everything
in a query.
I'll try and provide some sample data as an example -
CREATE TABLE #Tickets
TicketNo VARCHAR(4)
,DateUpdated DATE
INSERT INTO #Tickets VALUES ('44BS', '2014-01-01')
INSERT INTO #Tickets VALUES ('44BS', '2014-01-05')
INSERT INTO #Tickets VALUES ('44BS', '2014-01-07')
INSERT INTO #Tickets VALUES ('32VT', '2014-01-03')
INSERT INTO #Tickets VALUES ('32VT', '2014-01-09')
INSERT INTO #Tickets VALUES ('32VT', '2014-01-11')
So for ticket 44BS, I need to return the missing dates between January 1st and January 5th, again between January 5th and January 7th. A set-based solution would be best.
I'm sure this is easier than i'm making it. However, after playing around for a couple of hours my head hurts and I need sleep. If anyone can help, you'd be a job-saver :)
Thanks!!CREATE TABLE #Tickets (

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.

hi
i have sorted the internal table by field f1 and i need to insert the first row for each f1 entry.
I tried AT NEW f1. But that doesnt seem to work.
Kindlly help.
Thanks.*--ENSURE THAT age IS FIRST FIELD IN INTERNAL TABLE it_gir while declaring it.....
SORT it_gir BY age ASCENDING.
LOOP AT it_gir INTO wa_gir.
AT NEW age.
<b>*--if there are fields which are getting populated with **** instead of original values....then use below statement...</b>
read table it_gir index sy-tabix.
MOVE-CORRESPONDING wa_gir TO wa_final1.
APPEND wa_final1 TO it_final1.
clear wa_final1.
ENDAT.
ENDLOOP.
now it should definitely work.....
if not check in debugging mode if data exists or not....!!!

</HTML>Hi,
Let me make sure u r working with table control.
First u have to create a event(VALIDATE) to do the validation.
Inside the event,
1. First get the current index where user has pointed the curson
2. Once u get the index read the internal table with index value.
3. Now u can compare the col1 and col2 values and populate the error message.
1. DATA : lo_elt TYPE REF TO if_wd_context_element,
l_index type i.
lo_elt = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
CALL METHOD LO_ELT->GET_INDEX( RECEIVING MY_INDEX = l_index.
above code should be written inside the event.
Thanks, -
I don't want a new row for each line of text
I have exported a pdf document which is a table full of text in columns (by month). The conversion seems to react randomly so that in some places several lines of text in a column are converted to just one cell (great, just what I want) and then in others, a block of text gets split into a row for each line of text --- very annoying ...
What would make this happen? Is there a workaround so that you can tell the conversion how to react to blocks of text?
hope someone can helpFor optimal export the PDF needs to be a well-formed tagged PDF.
The basic PDF page content has no format, styling, rows, columns, etc.
Just objects painted to the PDF page at a specified location.
You can return to the authoring file, clean that up to support accessible PDF output, then post process the PDF with Acrobat XI Pro to finalize making the PDF PDF/UA compliant. Export of that would be better.
You can manually tag the PDF such that it is PDF/UA compliant than export from that . This would provide you better export.
You can clean up the export you already have.

Multiple parameters one row for each record
I have this query I want the user to be able to allow the user to enter multiple MATL_CODE_MOD as a parameters, the problem is that the GURMAIL table have multiple records one for each GURMAIL_MATL_CODE_MOD, so it will give me duplicates.. How I can code this, so I can allow the user to enter multiple MATL_CODE_MOD codes, and have only one row for each record...
and GURMAIL_MATL_CODE_MOD in ('8IBC','8IBD')
select
spriden_id,
spbpers_name_suffix name_suffix,
spbpers_name_prefix name_prefix,
spriden_last_name last_name,
spriden_first_name first_name,
spriden_mi mi,
srbrecr_term_code,
srbrecr_majr_code,
srbrecr_program_1,
saturn_midd.utlq.f_matl_code_type(srbrecr_pidm)
FROM
saturn.srbrecr,
saturn.spriden,
saturn.spbpers,
SATURN.SPRADDR,
general.gurmail
WHERE
spriden_pidm = srbrecr_pidm
and gurmail_pidm = spriden_pidm
AND spriden_pidm = spraddr_pidm
--and srbrecr_term_code = decode(p_term ,'%',SRBRECR_TERM_CODE,p_term)
and spbpers_pidm = spriden_pidm
and spriden_change_ind is null
--and gurmail_matl_code_mod
and SRBRECR_PROGRAM_1 = 'CMQ'
and GURMAIL_MATL_CODE_MOD in ('8IBC','8IBD')
--AND SPRADDR_ATYP_CODE = 'CM'
AND SPRADDR_STREET_LINE1 IS NOT NULL;Hi,
SELECT DISTINCT ...will keep duplicate rows out of the result set.
Depending on your data, another possibility might be to not join the table that contains GURMAIL_MATL_CODE_MOD. Do an EXISTS sub-query on that table instead.
If you need more help, post some sample data from all the tables, and the results you want from that data.
Simplify, if possible, You can probably post a problem with 2 or 3 tables, each with 2 or 3 columns, that will have the same answer.

Get lastest row for duplicates
I have an Excel spreadsheet that has multiple rows for a specific customer. I want to only keep the row for each customer that has the earliest shipping date but I want all the columns. Can I do that with PowerPivot and if so, how?
Hi RACAND,
Thanks for providing the Excel workbook. I've taken a look at the data and the rows that have been highlighted appear to be the rows with the latest shipment dates as opposed to the earliest ones.
If you are indeed trying to return values for the rows with the earliest shipment date then you can use the following DAX formula to create a calculated column that will flag the rows for each Customer ID that has the earliest shipment
date:
=
'Order'[SHIP_DATE] =
CALCULATE(
MIN('Order'[SHIP_DATE]),
ALLEXCEPT(
'Order',
'Order'[CUSTOMER_ID]
Note: If you want the opposite effect (i.e. flagging the latest shipment date per customer) then you can swap the 'MIN' function with the 'MAX' one.
This formula will return a 'true' or 'false' value per row. In the below example I have called the column 'FIRST_SHIP_DATE'.
On your customer table, you can then use the following pattern to pull back the values from the Order table for each Customer where the Order[FIRST_SHIP_DATE] has a true value.
=
CALCULATE(
LASTNONBLANK(
<<Put the order table column name here>>,
1
'Order'[FIRST_SHIP_DATE] = TRUE()
An example of this pattern being used to add the 'SHIP_TO_ADDRESS' column from the Order table onto the Customer table is...
=
CALCULATE(
LASTNONBLANK(
'Order'[SHIP_ST_ADDRESS],
1
'Order'[FIRST_SHIP_DATE] = TRUE()
After applying this pattern for two other columns I got the following result...
Hope this helps but if I have misunderstood part or all of your requirement, let me know ;)
EDIT: You can replace where I have used:
'Order'[FIRST_SHIP_DATE] = TRUE()
With just:
'Order'[FIRST_SHIP_DATE]
For example, we can update the following formula:
=
CALCULATE(
LASTNONBLANK(
'Order'[SHIP_ST_ADDRESS],
1
'Order'[FIRST_SHIP_DATE] = TRUE()
to be written as:
=
CALCULATE(
LASTNONBLANK(
'Order'[SHIP_ST_ADDRESS],
1
'Order'[FIRST_SHIP_DATE]
This is because the column already returns a true/false value.
Regards,
Michael

Hi,
I need to get the details for each user hit.
Apparently, this table has the IMPRESSIONS column which returns the total number of hitcounts and VISITS which counts the number of unique user who accesses the portal. What I am trying to look for is to get all the details per hitcount. I need to find out how many time a specific user accessed a specific page or iview.
I also used the table WCR_USERPAGEUSAGE, which I get the information of the users counted in the VISITS column in the first table.
I could not get the specific user per hit.
Please enlighten me if this is possible and how to do this?
Thanks!Hi Catherine,
Why not use the portal activity report iView?
In the portal activity report iView the 3rd option allows you to choose a page for example and see
the user who accessed it and how many times.
Thanks and BR,

Qry:How to get different price for each price list (variable area) in order
1-How to get different price for each price list (variable area) in order for sale. for the opportunity to display and select multiple prices.
2- I add a location store from a table in line item and I want to see this area in order,.
I 'm created 2 field location(item line and order), 1 table location
I tried this for exemple : select $ [userfieldlocation.OITW]Thanks Suda for your answer,
the Formatted Search for prices is OK, but for the Item locations in warehouse this is not so simple,
I must have several (at least 2) locations for the item in the Warehouse and a track of this location and search possibilities.
read carefully and imagine how (Management warehouse locations)
I added a user table '@Location' who linked to a user field 'U_Location in Item master data --> lnventory data line and an ather user field 'U_Location' in sales order
I met the value of location in the table (list of locations for any warehouse), I select the location of each item while receiving merchandise in the user field of inventory data line (Item M data) and this value appears in the sales order 'U_Location' user field ( only the location value in the default warehouse for this Item)
or
create an user field 'location' in Good receipt PO to fill it while receiving merchandise that appears in the sales order to give possibility to find/select the location of the item at this order and in Item master data
I think we will use all these tables
@LOCATION
PDN1
OITM
OITW
OWHS
RDR1
