How to populate values in F4 help based on another F4 help in a TMG

Hello All,
I have created a TMG for a table. Have added that to customization also. Now, in that table I have 2 fields say carrid and connid. In the F4 help of carrid, all carrids will be displayed. Now if the user selects one carrid, the next field connid should show only those connids related to carrid. How this can be achieved in a TMG. If in a module pool, we can write POV or etc. But in TMG, how can we ?

How to display a sequence in item?

hi! well, i donÂ´t know how to display a sequence in item. i created a sequence in sqlworkshop. now i want what the sequence will display in item(for example :P8_COD_SERVICES). I HOPE ANSWER. BYE
(AH! I TRYNG IN ITEM.DEFAULT VALUES BUT NOTHING)

Alvaro,
Maybe the item source type could be SQL Query and the query would be: select seq.nextval from dual. Or you could have a before-header page computation do the same thing for the item.

How to display data from a recordset based on data from another recordset

How to display data from a recordset based on data from
another recordset.
What I would like to do is as follows:
I have a fantasy hockey league website. For each team I have
a team page (clubhouse) which is generated using PHP/MySQL. The one
area I would like to clean up is the displaying of the divisional
standings on the right side. As of right now, I use a URL variable
(division = id2) to grab the needed data, which works ok. What I
want to do is clean up the url abit.
So far the url is
clubhouse.php?team=Wings&id=DET&id2=Pacific, in the end all
I want is clubhouse.php?team=Wings.
I have a separate table, that has the teams entire
information (full team name, short team, abbreviation, conference,
division, etc. so I was thinking if I could somehow do this:
Recordset Team Info is filtered using URL variable team
(short team). Based on what team equals, it would then insert this
variable into the Divisional Standings recordset.
So example: If I type in clubhouse.php?team=Wings, the Team
Info recordset would bring up the Pacific division. Then 'Pacific'
would be inserted into the Divisional Standings recordset to
display the Pacific Division Standings.
Basically I want this
SELECT *
FROM standings
WHERE division = <teaminfo.division>
ORDER BY pts DESC
Could someone help me, thank you.

Assuming two tables- teamtable and standings:
teamtable - which has entire info about the team and has a
field called
"div" which has the division name say "pacific" and you want
to use this
name to get corresponding details from the other table.
standings - which has a field called "division" which you
want to use to
give the standings
SELECT * FROM standings AS st, teamtable AS t
WHERE st.division = t.div
ORDER BY pts DESC
Instead of * you could be specific on what fields you want to
select ..
something like
SELECT st.id AS id, st.position AS position, st.teamname AS
team
You cannot lose until you give up !!!

How To Display Value In inputText When List Is Used

Hello,
I have a question regarding how to display value from List in a jsf page?
From a Map, i could display like
<ice:inputText id="plantno" value="#{bean.detailedRowData['plantno']}"So if I am using a List instead of Map, how can I refer value in List so that I could display my plantno?
<ice:inputText id="plantno" value="#{bean.?????}"Thanks

Create a backing bean method that fetches the value from the list for you.
<ice:inputText id="plantno" value="#{bean.plantNo}"/>
public class MyFunkyBean {
private List<String> rowdata;
public String getPlantNo(){
return rowdata.get(INDEX_AT_WHICH_THE_PLANTNO_IS_STORED);
}It really isn't possible to turn the list into a regular bean/entity?

How to display value in memory

How to display value in memory, except call function 'LIST_FROM_MEMORY' .
Thanks.

Hi
See this
may be useful
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens
SAP global memory retains field value through out session.
set parameter id 'MAT' field v_matnr.
get parameter id 'MAT' field v_matnr.
They are stored in table TPARA.
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data
to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
ABAP memory is temporary and values are retained in same LUW.
export itab to memory id 'TEST'.
import itab from memory Id 'TEST'.
Here itab should be declared of same type and length.

How to display values and new char line (blank line)

Hi,
In database, one field contains values followed by new character lines (blank lines) after blank lines there is no values. Finally, I would say the field contains values and blank lines. Every thing is fine in database.
In Crystal Reports the field is displaying only values. Need to display values and blank line.
User is asking after values new character lines (blank line) to be shown. They enter like that in an application. The user doubt is why report is not showing what they enter in the application.
In detail explanation, front end tool is ASP.NET and backend is SQL Server.
User enter some values in note field, after that they hit enter button in the same field, cursor will go next line...user may hit u2018enter buttonu2019 more than 5 times. So note field contain values and some blank lines which are created by after hitting enter button.
If user opens the application, they could see values plus blank lines in the note field.
They are fine with the application.
In Crystal Reports, the note field shows only values.
User is questioning that why we could not see in report we enter.
I checked in .Net application and SQL server database it is fine. It is displaying values and blank line.
Please help me out how to display values followed by blank lines in Crystal Reports - the way they enter in the application.
Thanks and Regards,
Manjunath N. Jogin

Hi,
Sharonmat,
I tried as you suggested. It is still displaying only values.
I would like to explain again.
it is not exactly null values.
In .Net application it is called 'new char line'.
it shows those many lines look like null.
it is working fine in database.
Why it is not working in Crystal Reports? I am wondering...
Thanks for your suggestion.
Debi,
User may enter any number of blank lines or they may not enter blank lines.
That is the reason I can not always give more height or blank text object.
Thanks for your suggestion.
Please suggest me some more suggestions,
Thanks and Regards,
Manjunath N. Jogin

How to get Value of a item of first record when current record is second

How to get Value of a item of first record when current record is second in Form6i ?
get_item_instance_property dose not allow to get value.

Gerd,
You're right, there are several other triggers that must be coded, but I was responding to Steve's statement about Inserting or deleting records from the multi-record block. For the record, I use the following to manage a Record Group:
* When-New-Block-Instance - Initialize the RG
* block Post-Query - populate the RG
* When-Create-Record - add new record to RG
* When-Remove-Record - remove record from RG
* block When-New-Item-Instance - capture previous value of the item or row
* When-Validate-Item - Item specific Insert, Update, Delete of values in the RG
There are a few other places as well, but these are the minimum. It might seem like a lot of code, but then again, I don't use this solution for every multi-line block. Like all tools, you use the right tool for the job. :-)

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,

How to acquire display value of selected item on select list? Or...

I have a select list generated from a SQL query that I need to get the display value from.
Ideally, the display value and the submitted value of the select list would have been the same, but I can't seem to get APEX to allow populating a select list's display value and submitted value fields with the same database column.
If you have any idea how to do either of the above, I'd love to hear from you here!
Cheers,
Ben

you forgot the extra quotes I guess:
declare
l_sql VARCHAR2(4000);
begin
l_sql := 'SELECT product_name,project_name,information_access_system,dataset_name FROM v_dms_product WHERE product_name = ''' || :P24_CHOOSEPRODUCT || ''' GROUP BY product_name,project_name,information_access_system,dataset_name';
return l_sql;
end;

How to retain value in LoV item in Tabular Form, after Page Refresh

Hi,
I have a tabular form, which contains 2 items(columns), of type "Select List - named LoV".
Now, 2nd item(column) in tabular form, that LoV should get populated based on user's selection value in first item LoV.
1. So how do I refer to the value, that user selected in first item's LoV? I will have to use this value as reference in LoV query of my 2nd item ( on this tabular form)
2. Everytime I select value in first item LoV, page gets refreshed, as my requirement is to calculate 2nd item's LoV based on selected value in first item. So after this page refresh, first item LoV loses its value that was selected before the page refresh happened. So how do i retain this value in first item LoV? I have an unconditional process, that on every submit(refresh) of page, I set all my items with their corresponding values. But problem is what do i mention there to refer to this first item ( of type LoV) of tabular form?
I looked in view source of my page, this item is referred as f03.
So i used "apex_application.g_f03", to set this item to its value, in my uncoditional submit process. But it did not work. I tried to refer this item as "f03" in this unconditional submit process. But still it did not help, the selected item loses its value after page refresh(submit).
Please help.
Thanks and Regards,
Ravi.

Hi Rave,
You will have to use Javascript and Ajax to change the values as ApEx submissions will lose your results unless they are saved into the database.
Remember, that as you are using a tabular form there will be lots of items called f01, fo2, fo3 etc on the page (one per row).

Is it possible to change the display value of a domain-based attribute?

Hello,
I've selected a domain-based attribute for one of the leaf member attributes in the same entity, aka parent id, since it's a self-referencing entity. However, I cannot find a way to display anything but the code value in the drop-down (see below).
Is there a way to change the display value so that I can choose the attribute from the entity from which I want the user to choose? In other words, I would like to display the hierarchy name instead of the code, which is really just the primary id.
Thanks in advance!
Ben Lezin

1. In the explorer page, settings dialog, you can change the display format to show only name.
2. We cannot use other freeform attribute as DisplayFormat, rather than Code Name. So there are 2 option here:
a. Remove HierarchyName attribute and just use Name attribute. In the next release, we will allow give Name, Code attribute a displayname, so you can give Name display name as "HierarchyName" in the SQL Vnext release.
b. Make a Business Rule to update Name when HierarchyName is changed.

How to keep values in text items.

Hi,

TEAM_LOV := select team d, team_id r from teams;
TYPE_LOV := select type d , type_id r from types where team_id=:P4_TEAM;
1. For P4_TEAM item is select list with redirect .
2. For P4_TYPE item is select list.
Problem:=
When i create a new record and enter new values in the text items above the P4_TEAM item and then selects the list of values from P4_TEAM then the values from the above text items gets clears . How to prevent the clearing the item values.
If i use select list with submit. then i have validation on two items so i gives validation errors.
Help !
Thanks,
Ramesh

Hi Ramesh,
I had the same problems and solved it with AJAX. then only the second list is updated and no submit or redirect is needed.
Otherwise you could set a condition for your validation, i.e. only if item is not null.
