Input enabled table with multiple rows

Hi All,
I have a scenario to create a table in webdynpro for abap. This is a user interface. Here user will be providing value for tabe in multiple rows. And once user will press the Save button then all the rows of table will be read and will be saved in database.
My problem is the table is displaying only one row as input enabled not all the rows. Can anyone please help on this? Points will be assured.
If I am providing rowCount = 2. Or more than 2 then it is creating short dump.
Thanks & Regards,
Ashvender

Hi Ashvender
In init method of your view :
Read the context node with which u have binded the table control fields.
Create a internal table same as structure of your context node
append blank records for as many editable rows u wanted
Bind the internal table.
Ex:
node_table TYPE REF TO if_wd_context_node,
elem_table TYPE REF TO if_wd_context_element,
stru_table TYPE if_v_table=>element_flight ,
lt_stru_table TYPE if_v_table=>elements_flight .
node_table = wd_context->get_child_node( 'TABLE' ).
clear: stru_table.
do 5 times.
append stru_table to it_table.
enddo.
node_table->bind_table( it_table).

Editable table with multiple rows

Hi All!
We're trying to develop some application in VC 7.0. That application should read data from some R/3 tables (via standard and custom functional modules), then display data to user and allow him/her to modify it (or add some data into table rows), and then save it back to R/3.
What is the best way to do that?
There's no problem with displaying data.
But when I try to add something to table (on portal interface), I'm able to use only first row of the table... Even if I fill all fields of that row, I'm not able to add data to second row, etc.
Second question. Is it possible to display in one table contents of output of several BAPIs? For example we have three bapis, one displaying user, second displays that user's subordinates, and the third one - that user's manager. And we want one resulting table...
And last. What is the best way to submit data from table view in VC (portal) to R/3 table? I understand that we should write some functional module, that puts data to R/3. I'm asking about what should be done in VC itself. Some button, or action...
Any help will be appreciated and rewarded :o)

Issue in retrieving all the records from ADF Table with multiple row

Hi,
As per my requirement, I need to fill the table with multi selected LOV values and when user clicks on commit, I need to save them to database.
I am using ADF 11g, Multi select table. Using the below ADD method, I am able to add the records but if user clicks on cancel, I need to remove those from view and clear the table as well.
But the Issue I am facing is, in my cancel method, always I am getting half of the records. Lets assume table contains 100 records but in my cancel method, I am getting only 50 records.
Please let me know what is the issue in my source code.

Adobe Form Table with multiple rows

Hi,
I am facing problem with mutliple rows item in the table. A row which doesn't have data is occuping the space in the form. Need solution to remove the space .
i used the code in Form CALC in client.
if (HasValue($) == 0)
then $.presence = "hidden"
else $.presence = "visible"
endif
But it is not working. And also i need display a text field based on the condition.in the form How can i write code in the Form CALC. Plz help me out in this.
Thanks & Regards,
Narasimha

Hi Narsimha,
First of all why is your blank row getting displayed?Adobe automatically takes care of this. It would display a new row only if there's flow of data in the next row. i.e. if you have a new item to be displayed in this new row.
You must check your table properties first.
For hiding fields i can help you.But I m not sure if this issue is still open.

Powerpivot excel pivot-tables with multiple rows (problem expand / collapse)

Hello,
I made a pivot table with powerpivot so I get kind of data:
The problem I have is that when I reduced the city of Bordeaux for example, given this city are reduced both that really interests me as the other non-company (all cities Bordeaux are reduced).
I would like to know how to get it is there that the city which interests me is reduced?

Hi,
As I have no idea of your PowerPivot data. And I have a litter confused about
'the city which interests me is reduced' .
Did you want to get the city whose volume（maybe sales volume) is reduced than last year ?
If so,I suggest you create a calculated column in PowerPivot to get the YTD of previous year using DAX. then in pivot table you can use this dimension to do a filter.

Empty table with multiples rows and 2 columns for processing data

Hi,
I am very new to adobe forms. I have the requirement that the user will enter some data in the table rows and I should process them to update in a z-table as well as use that data for MB1A tcode. I am not sure what to use here. Which is the best. I dont know anything about webdynpro. Can it be done directly in SFP transaction without using web-dynpro?
Also if I need more rows I should give them the option to add rows. How does the submit button work here when the user enters the data in all the 10 rows.
I heard about web services and I know a little about it, can it be achieved though that? Please help me. I need to finish 4 forms like this and each form should take me to the next form level.
Kaps.

Hello!
You don´t have to tell me, I am the ABAP developer as well. I know that there is very little like ..."career" value in learning scripting in some obscure languages like Java script or Form Calc for Adobe forms. But trust me, you won´t have to learn much. You will have to learn how to manipulate the presence of form fields (or variable values, but that is the same like setting the presence to hidden, you only pass a constant or any other value).
In the mentioned guide, in the last chapter you can just copy and next paste the ready to use scripting bacis. I think you should find the add/ remove row scripts there as well.
The right scenario is not always easy to pick, consider this:
- how many forms at the same time will the user have to fill? (if one --> offline, if more --> portal/ WD)
- do you want the user to work with the NW portal? do you have licenses for the new users? (WD)
- how often will the people fill their forms? how important the processes are? how many values will come from the backend tables (like how many search helps you would use if you can)
etc. etc.
Hope that clarifies things a little for you

Web dynpro screen with multiple rows with columns that can be edited

Web dynpro screen with multiple rows with columns that can be edited individually:
Hi
I am busy creating a screen in web dynpro for ABAP which we would like to make available via Portal ESS (Portal 7).
I need to add 'n type of table (or almost something like Excel) or something in which someone can type a few paycode numbers (there should be lets say 10 blank rows in which info can be typed in and if I click on a button or so, more rows must be added if necessary. Then in the other colums stuff like amounts must be entered which one should also be able to edit then and there.
Can anyone assist in what I can use for this? There does not seem to be some existing element that I can use.
Help will be appreciated.
Regards
Debbie

Hi Debbie,
Whiel Creating table you need to be care full that use chose INPUT FIELD as the CELL EDITOR. Just guessing that if ur table is not editable u might have choosen TextView as default cell editor type.
check link for details on TABLE UI
[http://help.sap.com/saphelp_erp2005/helpdata/EN/b5/ac884118aa1709e10000000a155106/frameset.htm]
easy way is to first add UI ELEMENT TABLE to your VIEW, then right click over it & select create binding from context. After you have a pop up where you can select what columns you want what should be its cell editor etc.
Greetings

Issues in Table with Multi-Row Insert

I have created a master detail screens using jheadstart on 2 separate pages, Master in the Form layout and detail in the Table Layout with multi-row insert, update and delete flags ON. Have set the New Rows count = 2.
Issue 1
If I try to delete any existing rows, it gives error for new rows saying value is required for the mandatory fields. It should just ignore the new rows if I have not updated any values for any attributes in the those row(As it does for non Master-Detail Table layout). I guess this might be happening because the jheadstart code is setting the foreign key for new rows the detail, but not resetting the status of the rows back to INITIALIZED.
I also noticed that the create() of underlying EO is getting called for those blank rows when I click on 'Save' button, even if I have not changed any data in those rows.
Issue 2
When I try to select the new rows also for deletion, I am getting a '500 Internal Server Error' with following stack trace... This is also happening for normal (non Master-Detail) Table layout.
java.lang.IllegalStateException: AdfFacesContext was already released or had never been attached. at oracle.adf.view.faces.context.AdfFacesContext.release(AdfFacesContext.java:342) at oracle.adfinternal.view.faces.webapp.AdfFacesFilterImpl.doFilter(AdfFacesFilterImpl.java:253) at oracle.adf.view.faces.webapp.AdfFacesFilter.doFilter(AdfFacesFilter.java:87)
Issue 3
I have put some validation code in the validate() method in the MyEntityImpl.java class.
The validate method seems tobe getting called lots of times, in my case 20 times, where the new rows are just 2.
Environment:
Jdeveloper 10.1.3, JHeadStart 10.1.3 build 78, Windows XP
thanks

Thanks for the reply.
Issue 1:
What I have observed that in case of multi-row select enabled tables, the blank rows do not have any data. This is because the EO's create() method is called only when we post the data using 'Save' button. Thus the Foreign Keys are also not setup. This is a correct behavior since create() and FK setups etc should get done only if the user has inputted any value in the new rows and thus intend to insert new data into the table.
I am able to find the exact cause of this issue. It is happening because in the details table, I have a column which needs tobe shown as checkbox. Since we can only bind checkbox to an Boolean attribute in VO, I have created a transient attribute of type Boolean, which basically calls the getter/setter of actual attribute doing the String "Y"/"N" to true/false conversion. Here is code for the transient attribute getter/setter
public Boolean getDisplayOnWebBoolean() {
return "Y".equals(getDisplayOnWeb()) ? Boolean.TRUE : Boolean.FALSE;
public void setDisplayOnWebBoolean(Boolean value) {
if(Boolean.TRUE.equals(value))
setDisplayOnWeb("Y");
else
setDisplayOnWeb("N");
Now when I click on the "Save" button, the setter for the boolean field is getting called with the value = false and this is resulting into the row being maked as dirty and thus the validation for the required attributes is getting executed and failing.
Issue 2:
Confirmed that correct filter-mapping entries are present in the web.xml.
Now when I select the new blank rows for deletion and click save, following exception is thrown:
java.lang.ClassCastException: oracle.jheadstart.controller.jsf.bean.NewTableRowBean at oracle.jheadstart.controller.jsf.bean.JhsCollectionModel.getRowsToRemove(JhsCollectionModel.java:412) at oracle.jheadstart.controller.jsf.bean.JhsCollectionModel.doModelUpdate(JhsCollectionModel.java:604) at oracle.jheadstart.controller.jsf.lifecycle.JhsPageLifecycle.processModelUpdaters(JhsPageLifecycle.java:541) at oracle.jheadstart.controller.jsf.lifecycle.JhsPageLifecycle.validateModelUpdates(JhsPageLifecycle.java:571)

How to create a table with multiple select on???

Hi all,
I am new to webdynpro and my requirement is to create a table with multiple selection on.I have to add abt 10 rows in the table but only 5 rows should be visible and moreover a verticalscroll should be available to view other rows.Can anybody explain me in detail how to do that.Please reply as if you are explaining to a newcomer.Reply ASAP as i have to do it today.
Thanxs

Hi,
1. Create a value node in your context name Table and set its cardinality to 0:n
2. Create 2 value attributes within the Table node name value1 and value2
3. Goto Outline view> Right click on TransparentUIContainer>Apply Template> Select Table>mark the node Table and it's attributes.
you have created a table and binded its value to context
Table UI properties
4.Set Selection Mode to Multi
5.Set Visible Row Count to 5
6.ScrollableColCount to 5
In your implemetaion, you can add values to table as follow:
IPrivate<viewname>.ITableElement ele = wdContext.nodeTable().createTableElement();
ele.setValue1(<value>);
ele.setValue2(<value>);
wdContext.nodeTable().addElement(ele);
The above code will allow you to add elements to your table node.

Select on table with 1800 rows is slow

I have a table with 1800 rows. Each entry has a geometry position and a geometry polygon around the position. I am using the polygon to detect which (other) entries are near the current entry.
In the following testdata and the subsequent query, i am filtering on 625 (of 1865) rows, and then using the .STContains-method to finding other rows (the testdata is fully found by this query, in the live database the values are not so regular as in the testdata.
The query take 6500 ms. In the live database, only 800 records are (yet) in the table, and it takes 2200 ms.
select SlowQueryTable.id
from SlowQueryTable
inner join dbo.SlowQueryTable as SlowQueryTableSeen
on SlowQueryTable.[box].STContains(SlowQueryTableSeen.position) = 1
where SlowQueryTable.userId = 2
(The query in the live system is even more complex, but this is main part of it and even simplified as it is just takes too long).
This script generates test data and runs the query:
-- The number table is just needed to generate test data
CREATE TABLE [dbo].[numbers](
[number] [int] NOT NULL
go
declare @t table (number int)
insert into @t select 0 union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9

--on SlowQueryTable.position.STDistance(SlowQueryTableSeen.position) < 5
where SlowQueryTable.userId = 2
drop table #t1
drop table SlowQueryTable
drop table numbers
Using an explicit index hint does do the job, but then the query gets slow if i change the where clause:
select SlowQueryTable.id
into #t1
from SlowQueryTable
with (index([SlowQueryTable_box]))
inner join dbo.SlowQueryTable as SlowQueryTableSeen
on SlowQueryTable.[box].STContains(SlowQueryTableSeen.position) = 1
where SlowQueryTable.userId = 2
leads to 600ms, and changing the where clause
where SlowQueryTable.id = 100
slows it again down to 1200ms. Filtering on ID get massively slowed down when using index hint on the spatial index.
Since the table in the live system will grow to 10000+ rows, and the query is called often by users, I badly need a more efficient query.
Do I have to create a different queries for each use-case, some with index hints and some without?

I've run your example and can confirm your results. There's a couple of things that I noticed though.
After looking at query plans, it's not a matter of "with spatial index" vs. "without spatial index". You have two spatial indexes, one on each column (position and box). When you don't hint the "box" spatial index, the query
uses the "position" spatial index. Because of what they are indexing (points vs. polygons), the "box" spatial index requires a lot more IO. With some (non-spatial) predicates, the "box" spatial index gives better performance,
with others the "position" one does. I've yet to figure out exactly why (short on time, I might get back to it in future), but you can examine query plans and use the spatial index diagnostic procs (e.g. sp_help_spatial_geometry_index_xml ) in
addition to the diagnostics you're running to see why and if you can find a better performing plan/index.
Bear this in mind. Given a choice of multiple spatial indexes, the SQL Server query optimizer is not able to choose (for the most part, IO etc. aside), which one is best. Also, there is usually only one choice of spatial query plan shape, in general. If
your query is more complex than the one in your example, you might benefit by breaking it in two: one query to filter out all the rows and predicates that don't use a spatial index and one query that uses the spatial index on the subset. I've had good
luck with this other situations with complex queries involving spatial predicates. This method may not be applicable to a spatial query as simple as the one in your example, however.
Hope this helps, Bob

Import the table with 0 rows

Hi
I have a problem to import a dump that contains the tables with 0 rows.
When i exported from ORACLE 11.2 64 bit on SERVER 2008 i noticed that log didn't confirm the tables with 0 rows.
When i want to import to ORACLE 11.2 64 bit on other SERVER 2008 i have a lot of errors on this tables with 0 rows.
In the log i get the same tables with 1 row at least, but no one with 0 rows.
I open my dump in TEXTPAD and i see it contains "CREATE ....." these tables.
I don't understand why it happens. I used FUll DUMP by SYS, it didn't help.
This is not first time when i export and import dumps,no errors.
I'm using command "EXP" and "IMP" and every time it's ok.(IF it's a releavent)
Why it happens? any solutions for this issue?
Thanks

I've found (i guess so) solution to this issue
here are two links to this new feature that is called deffered segment creation
The reason for this behavior is 11.2 new feature ‘Deferred Segment Creation‘ – the creation of a table sent is deferred until the first row is inserted.
As a result, empty tables are not listed in dba_segments and are not exported by exp utility
http://www.nativeread.com/2010/04/09/11gr2-empty-tables-skipped-by-export-deferred-segment-creation/
http://antognini.ch/2010/10/deferred-segment-creation-as-of-11-2-0-2/
And this is i've found in official documentation from oracle
Beginning in Oracle Database 11g Release 2, when creating a non-partitioned heap-organized table in a locally managed tablespace, table segment creation is deferred until the first row is inserted. In addition, creation of segments is deferred for any LOB columns of the table, any indexes created implicitly as part of table creation, and any indexes subsequently explicitly created on the table.The advantages of this space allocation method are the following:A significant amount of disk space can be saved for applications that create hundreds or thousands of tables upon installation, many of which might never be populated.Application installation time is reduced.There is a small performance penalty when the first row is inserted, because the new segment must be created at that time.
To enable deferred segment creation, compatibility must be set to '11.2.0' or higher. You can disable deferred segment creation by setting the initialization parameter DEFERRED_SEGMENT_CREATION to FALSE. The new clauses SEGMENT CREATION DEFERRED and SEGMENT CREATION IMMEDIATE are available for the CREATE TABLE statement. These clauses override the setting of the DEFERRED_SEGMENT_CREATION initialization parameter.
+Note that when you create a table with deferred segment creation (the default), the new table appears in the _TABLES views, but no entry for it appears in the SEGMENTS views until you insert the first row. There is a new SEGMENTCREATED column in _TABLES, _INDEXES, and _LOBS that can be used to verify deferred segment creation+
Note:
The original Export utility does not export any table that was created with deferred segment creation and has not had a segment created for it. The most common way for a segment to be created is to store a row into the table, though other operations such as ALTER TABLE ALLOCATE EXTENTS will also create a segment. If a segment does exist for the table and the table is exported, the SEGMENT CREATION DEFERRED clause will not be included in the CREATE TABLE statement that is executed by the original Import utility.

I have regisetred a EIT with multiple rows Yes, can we change it NO now.

I have registered a EIT with multiple rows Yes, can we change it NO now.

Hi,
Yes you can change this through back-end.
Register extra information (types) concurrent program run the package HR_REGISTER_EITS and insert definintion of an EIT in respective INFO_TYPES tabel for example if person EIT then definition is stored in PER_PEOPLE_INFO_TYPES.
In this table we have column MULTIPLE_OCCURENCES_FLAG which can have value as Y or N, Y - Multiple entries allowed, N - Multiple entries not allowed.
You need to update the value of this flag to N for your EIT definition and you are done.
Thanks,
Sanjay
