Mass Updating of Selected Rows

(As you can see from my low number of posts I'm new to ApEx, so any information you can provide is appreciated.)
Hi,
I've been asked to include what I consider a heavy duty feature on a report. It has been requested that there is a form region above a report region. The form will have some fields on it to be used to mass update selected rows.
For instance, let's say the report is a list of employees and their dept and the form has a dropdown dept field that contains a list of depts. They want to be able to select certain employees on the report, then select a dept from the form and then click an Update Rows button. They want the selected rows to be updated with the selected dept. * Also, they don't want the report to be editable. * The only way to update any rows is thru the Update Row button.
I'm new to ApEx and can code in JavaScript, but am not an expert in either. And, I'm still trying to figure out what JavaScript syntax works in Element Attributes, etc. fields. But, I digress.
I have looked over several threads, and went to several demo pages, and have learned some things. Hopefully they are correct. If not, please correct me.
- Using the Row Selector is tricky.
- You can get the Row Selector on a regular SQL report by changing it to Updateable SQL, adding the Row Selector type, and changing it back.
- You can only see row information on a column if the column is editable.
I now have a report that is NOT editable and has NO editable columns. And the report has the Row Selector. Also, the ID (key) of each row is the first column of each row. (It's a link field that populates another page.) With the ID I can populate the correct record. I'm thinking I need to populate the ID again in another column into a text field and then be able to access that value on the selected rows.
Here's my dilemma. (That is, if I'm on the right track.) I need to know which rows are selected and then access the ID (key value) of that row. After that I can let my PL/SQL do the work.
- - 1. How does the 2nd ID need to be defined such that people can't edit it, but the value can be retrieved? And, how is this done? I assume something can be put in the Element Attributes. If so, will you please provide the code?
- - 2. What is the trick to knowing which rows are selected? An example snippet of code would be great here too.
- - 3. Also, tell me if I'm on the wrong track and need to provide a solution in a different way.
Sorry for the novel, but I wanted you to have a good idea of what I'm trying to accomplish so you may provide appropriate answers.
Thanks much, Tony

Hi Tony,
check out the following threads:
Re: Reference a value within a report????
Re: MRU - trying to restrict UPDATE to only certain users - everyone INSERT
BTW, you don't have to use any JavaScript. When you write your "Update pl/sql process" for the tabular form, just reference you page item which contains the department for your mass update.
eg.
FOR ii IN 1 .. Apex_Application.g_f01.COUNT
LOOP
    UPDATE EMPLOYEES
      SET DEPARTMENT_ID = :P4_NEW_DEPARTMENT_ID
    WHERE EMPLOYEE_ID   = Apex_Application.g_f02(Apex_Application.g_f01(ii))
END LOOP;Hope that gives you a direction how to solve that

How to update the restricted rows that were selcted using fetch

Hi
I have to fetch one row at a time from my staging table using JDBC Sender Adapter, which is configured against AS400 DB2 and push it to R/3.
The select SQL looks like this in JDBC Sender Adapter
 select jedata, oxruns from fxjrnep2 where oxsts=' ' fetch first 1 rows only
 and
update sql is
 update suplib.FXJRNEP2 set OXSTS='SUC' where OXSTS=' ' 
The problem here is my select gets one row, which is what i want, but my update actually updates all the rows that satisfied the where condition oxsts=' ' instead of one.
I couldn't use fetch first 1 rows only at the end of the update sql to update the selected row. DB2 does not allow fetch in update sql.
Can anyone suggest solution here or recommend alternative?
Best Regards
Venkat

check for update query where u can club the select stmt u had used with udpate like:
update suplib.FXJRNEP2 set OXSTS='SUC' where OXSTS = (select jedata, oxruns from fxjrnep2 where oxsts=' ' fetch first 1 rows only
just need to try combinations of this type.
if still this is not working use a bpm and get all the records where OXSTS is null and process record one by one within a block

Mass Update of date in Qualified table

I having problem in updating End availability date in Partner Specific Data (which is a qualified table). How can do a mass update of selected records. I have written an assignment expression which has no error but it is not doing the update.
Regards,
Marcel

Hi Marcel
Assignment and validation does not work well for qualified table. It will work for only first qualified linked record and not all.
for mass update you can use import manager map the date qualifier field and select replcae action for qualified update in the destination item.

Select for update returns no rows even though there is no locking thread

I'm using Ibatis library over oracle sql for my query. The select for update statement returns no rows. This happens intermittently. When this was happening last time, I executed the select statement on sqldeveloper (but without the 'for update') and got rows. This situation is not easily reproducible so I've not yet been able to ascertain whether rows are returned on sqldeveloper with the 'for update' clause. But I know for sure that there was no other thread locking the rows. How could this be happening?

The select for update statement returns no rowsWhy do you think that a select for update will always return rows?
the for update clause if there not to garantee the presence of rows but to lock the row when it is present
sql> select * from t;
         A          B C
         1          1 step1
         2          2 step2
         3          3 step3Then session 1 issues the following select
SELECT     *
      FROM t
     WHERE a = 1
FOR UPDATE NOWAIT;If session 2 issues the same select before session 1 commits or rolls back
SELECT     *
      FROM t
     WHERE a = 1
FOR UPDATE NOWAIT;It will get the following error
ERROR at line 1:
ORA-00054: resource busy and acquire with NOWAIT specifiedBut if session 2 issue such a kind of select
sql> SELECT     *
2        FROM t
3       WHERE a = 99
4 FOR UPDATE NOWAIT;
no rows selectedYou see then that a select for update can return no rows

After upgrading to CF10, the selected row of my cfgrid is no longer passed on form post.

I have a cfform which contains a cfgrid and prior to the 9 to 10 update, upon submission of the cfform, the selected row of the grid was passed/posted to my form action page as:
__CFGRID__gridForm__renewalGrid
This contained all the data from the selected row, I.e.:
__CFGRID__COLUMN__=PROJECTID; __CFGRID__DATA__=T01081002AP; __CFGRID__COLUMN__=APPLICATIONS; __CFGRID__DATA__=PQFD; __CFGRID__COLUMN__=OWNERUID; __CFGRID__DATA__=HT2008; __CFGRID__COLUMN__=TEAM; __CFGRID__DATA__=Roberts; __CFGRID__COLUMN__=ROLE; __CFGRID__DATA__=AASBOAPMX; __CFGRID__COLUMN__=REGION; __CFGRID__DATA__=Southwest; __CFGRID__COLUMN__=EXISTING; __CFGRID__DATA__=K8045F; __CFGRID__COLUMN__=SOD; __CFGRID__DATA__=0; __CFGRID__COLUMN__=INITIALEMAILDATE; __CFGRID__DATA__=01/28/2013; __CFGRID__COLUMN__=MESSAGEDATE; __CFGRID__DATA__=; __CFGRID__COLUMN__=SECONDEMAILDATE; __CFGRID__DATA__=; __CFGRID__COLUMN__=ESCALATIONDATE; __CFGRID__DATA__=; __CFGRID__COLUMN__=COMPLETEDBY; __CFGRID__DATA__=TH2878; __CFGRID__COLUMN__=COMPLETIONDATE; __CFGRID__DATA__=02/06/2013; __CFGRID__COLUMN__=MONTHPULLED; __CFGRID__DATA__=Jan2013; __CFGRID__COLUMN__=TOTALITEMS; __CFGRID__DATA__=2; __CFGRID__COLUMN__=RELIEVINGPSA; __CFGRID__DATA__=; __CFGRID__COLUMN__=MODIFIEDBYTS; __CFGRID__DATA__=02/06/2013; __CFGRID__COLUMN__=MODIFIEDBY; __CFGRID__DATA__=T228Y8; __CFGRID__COLUMN__=CREATEDBY; __CFGRID__DATA__=KV3M36; __CFGRID__COLUMN__=CREATEDTS; __CFGRID__DATA__=01/28/2013; __CFGRID__COLUMN__=NEWSA; __CFGRID__DATA__=; __CFGRID__COLUMN__=DELEGATESTATUSNOTE; __CFGRID__DATA__=Access; __CFGRID__COLUMN__=STATUS; __CFGRID__DATA__=Completed; __CFGRID__COLUMN__=DATATYPE; __CFGRID__DATA__=Appl New
After upgrading to CF10, and with no changes to the code, performing this same process, __CFGRID__gridForm__renewalGrid is still passed in the form scope to my action page, but now it is empty.
I have not yet uninstalled CF9, so I brought it up on a different port, and I can run the same code as CF9 or CF10 and watch... in 9 the selected row is passed, in 10 it is empty.
Is this a bug? Is there a work around? Please help.

appears that apple has changed SMB code, and now its not possible login from windows on mac.
i installed snow leopard and now works fine.
apple is capable to make it run paying new license of smb code, but isnted of this, apple has created new protocol smbx and now, all others need to adapt your code to apple..
bad movement.. i am thinking sell imac and no back to apple anymore..

Selected rows appear in random order when selected from ADF Table

Hi All,
I am working in ADF 10.1.3
I have a ADF Table with a multi select option associated with a DataBean, My requirement is when I select multiple rows from the table and click on some button to goto next page, the selected rows are not getting populated as per the selection order.
Example: If I select 1st,3rd,5th,7th,9th rows from the ADF Table then in the next page I see the results as 3rd,1st,5th,9th,7th. - Randomly it is getting displayed.
I am using the following code to get the records from Multi select ADF Table.
I am adding the selected records to a List.
selectedRowSet = this.getTable1().getSelectionState().getKeySet();
rowSetIter = selectedRowSet.iterator();
if (selectedRowSet.size() > 0)
Integer index = Integer.parseInt((String) rowSetIter.next());
Object rowData = this.getTable1().getRowData(index.intValue());
The order is getting jumbled when I see the final list.
Pls help me in this.
Thanks

Hi Frank,
Thanks for the update.
We are using 10.1.3.3 and already our application in QA Testing. User need this to be fixed. Is there any work around for this problem?
Thanks

To capture the selected rows along with edited field contents in alv report

Dear All,
         I do have requirement where, in alv report output one field is editable and need to save the content of the edited field along with the selected rows.
         For example If there are 10 records displayed in the alv output with 20 fields.
Out of this 20 fields one field (say XYZ) is editable. Also i have already created a new pushbutton (say ABC) on alv output. Now in the alv output if we maintain some value in the field (XYZ ) for the 2nd and 4th record and select this two records, and when clicked on the pushbutton (ABC) it has to update the DB table.
      I am using the Func Module 'REUSE_ALV_GRID_DISPLAY'.
      Your early reply with sample code would be appreciated.
Thanks in Advance.

HI Naveen ,
There is an import parameter "i_callback_program" in the function module,
plz pass the program name to it.
Capture the command by passing a field of type sy-ucomm to "I_CALLBACK_USER_COMMAND ". Check the returned command and
and program a functionality as desired.
u can try the event double_click or at line selection. there u can use READLINE command to c if the line has been selected.
In case it is , process the code segment.

Pop up based on selected rows

Hi,
I have a multi-row select report with checkboxes. I would like to have it so you can check off your desired rows and click a button to have another window popup with the row information displayed in a different layout. The reason I am doing this is because I want to print specific rows (3 at a time, actually) in a particular format (ie not horizontally). I can get this to work with static fields in the region but cannot make the leap to multi-row select.
I'm thinking it's a combination of passing htmldb_application.g_f01 to pick the checked rows and then have javascript loop through the values in the report and place them in fields on the pop up. I found other postings, but they were for update of the multiple rows: I'm looking to just copy the text from the rows themselves to another window.
Is this possible?
I want a specific format to print out data in non-row fashion for a select set of data.
Does this make sense?
Thank you,
Dean

I believe I was getting caught up because I was trying to mix server side and client side functions.
I ended up doing two things slightly different.
Created a new small table to house my selections:my_print.
I had check boxes on the rows and an after submit process that would delete the rows in the selection table and insert the key values of those selected.
BEGIN
DELETE from MY_PRINT;
FOR i in 1..HTMLDB_APPLICATION.G_F01.count
LOOP
INSERT INTO MY_PRINT (CARD_ID) VALUES (HTMLDB_APPLICATION.G_F01(i));
END LOOP;
END;
Then when I added a Submit "Print" button that took you to another page. That page was a print-friendly formatted report which selected the rows off the my_print keys. To get the format I ended up modifying the report template behind the page. This required a little trial and error with the different template types but I got what I wanted with a vertical named template and custom HTML tagging on the Row Template to build the page like a table.
It's all server side now and loads within the page, rather than a pop-up.
It accomplished the ultimate goal of being able to print selected rows in a format I liked. Plus, doing it this way was way easier than trying to code it all with a pop-up.
good luck
dean

How to get selected row values in a table using check box

Hi ADF Experts,
JDEV Version 11.1.1.7.0
My requirement is getting the selected row valuesof a af:table using a checkbox(multi select).
Thanks,
Animesh

Hi,
add a transient attribute to the POJO entity and update this through a check box. The ensure you have autosubmit=true set on the check box. In a value change listener set or remove the row's checbox attribute value

A selected row in af:table does not get sorted.

Hi,
When a table supports single selection and the table contains quantity of rows gt it can fit into its viewport, then, on sorting, selected row gets out of the sorting process. But when you move to the end of the table, select a row there and then sort the table, then all rows sorted correctly. The selected row, after sorting, always set as a first row in the current viewport, doesn't matter whether it is in the order or out of it.
Noteworthy, when number of rows is lt the viewport allows:
1. sorting works as it should to;
2. on sorting/PPR'ing, as it gets some time, one can see how the viewport updates in two steps and in the first step the first row is the selected one.
JDev's version is 11.1.1.3.0.
VO, iterator and tree bindings, af:table all the props related to data retrieving, fetching and row displaying have default values.
What can cause that?
Thx,
Y.

Hi,
so what you are saying is that the selected table row is not sorted but added on top. I tried to reproduce this with 11.1.1.3 but can't see the issue. I tried with editable and read-only tables

Error in receiving tableview data for selected row

Hi Collegues ,
We plan to realize an application for the maintanance of planning data . In the first step we created a value help page by using a tableview with iterator class ( 1 of the 3 methods of the Interface was filled with logic ) . We don't use any controller for that application .
A global internal table with the relevant help value data ( fgrvalues ) is used for the tableview and the call is :
TYPE I .
+CLASS CL_HTMLB_MANAGER DEFINITION LOAD.
CLEAR ONCLICKEVENT.
IF EVENT_ID = CL_HTMLB_MANAGER=>EVENT_ID.
 EVENT_DATA = CL_HTMLB_MANAGER=>GET_EVENT( REQUEST ).
 IF ( EVENT_DATA IS NOT INITIAL ) AND
 ( EVENT_DATA->EVENT_TYPE = 'click' ) .
 ONCLICKEVENT = EVENT_DATA->SERVER_EVENT .
 ENDIF.
ENDIF.+
CASE ONCLICKEVENT.
WHEN 'take' .
 TABLE ?= CL_HTMLB_MANAGER=>GET_DATA( REQUEST = REQUEST
 NAME = 'tableView'
 ID = 'fgr1_vhelp' ) .
 TABLE_EVENT = TABLE->DATA.
 IF TABLE_EVENT->SELECTEDROWINDEX IS NOT INITIAL.
 ROWSELECTION = TABLE_EVENT->SELECTEDROWINDEX.
-> ROWSELECTION - Content is now the index of the selected tableview row
We always get the selected row in TABLE_EVENT->SELECTEDROWINDEX and the table TABLE_EVENT->ALLCOLUMNNAMES filled ( column ZX_FGR1 is the 2nd column )
but we never got the tableview data for that tableview row no matter what we tried . We tried it with a tableview-event fired on 'rowselection' by user line-selection . We have deactivated the iterator or changed the BPS design value . With the same result - nothing was given back .
We found that the System-Call Return value of :
+system-call ict
did
ihttp_scid_get_form_field
parameters
m_c_msg " > c handle
name " > form field name value " < form field value
 m_last_error. " < return code+
in the method IF_HTTP_ENTITY~GET_FORM_FIELD is empty . M_LAST_ERROR occurs with value '20' .
+ ASSIGN ROWSELECTION TO .
COLUMN_VALUE = TABLE_EVENT->GET_CELL_VALUE( ROW_INDEX =
COLUMN_INDEX = '2' ). -> Column Value is empty !!+
 +CALL METHOD TABLE_EVENT->GET_CELL_VALUE
 EXPORTING
 ROW_INDEX = TABLE_EVENT->SELECTEDROWINDEX
 COLUMN_INDEX = '2'
 RECEIVING
 VALUE = COLUMN_VALUE -> Column Value is empty !!+
 +CALL METHOD TABLE_EVENT->GET_SIMPLE_DATA ....
 -> Column Value is empty !!+ *----
What could be the reason for that problem ? In generally it must be possible somehow to read the tableview data for one or all rows of the mentioned tableview .
We hope that someone can help and are very thankful for a hint or solution . If you need more details please let us know .
Please Remark: It's no solution for us to read the data by using the created internal table fgrvalues and the selectedrowindex cause in a later step we plan to update an ODS table with the manual modified planning data of an editable tableview .
Thanks a lot in advance
Dirk Läufer

Hi collegues ,
It's done .
After we've got a very helpful little hint from Brian :
The <htmlb:tableView> renders a table to the browser. It does not keep a copy of the table. The browser will also never return the table. Never. What it can return are inputfields for each cell. But then only if each cell is custom rendered as an inputfield.
we could certainly solve the problem .
We set the field we want to get back from table view on not editable inputfield via the tableview-iterator method IF_HTMLB_TABLEVIEW_ITERATOR~RENDER_CELL_START :
DATA: LCL_TABLE TYPE REF TO CL_BSP_BEE_TABLE ,
 LCL_INPUTFIELD2 TYPE REF TO CL_HTMLB_INPUTFIELD .
CASE P_COLUMN_KEY .
WHEN 'ZX_FGR1'.
* Field Firm Group
 CREATE OBJECT LCL_INPUTFIELD2.
 LCL_INPUTFIELD2->ID = P_CELL_ID.
 LCL_INPUTFIELD2->WIDTH = '100%'.
 LCL_INPUTFIELD2->MAXLENGTH = 4.
 LCL_INPUTFIELD2->TYPE = 'STRING'.
 LCL_INPUTFIELD2->DESIGN = 'STANDARD'.
 LCL_INPUTFIELD2->DISABLED = 'TRUE'.
 LCL_INPUTFIELD2->VALUE =
 GET_COLUMN_VALUE( COLUMN_NAME = 'ZX_FGR1').
 P_REPLACEMENT_BEE = LCL_INPUTFIELD2 .
Now the method in OnInputPorcessing:
TRY.
 CALL METHOD CL_HTMLB_MANAGER=>GET_SIMPLE_DATA
 EXPORTING
 REQUEST = RUNTIME->SERVER->REQUEST
 ID = 'fgr1_vhelp'
 ROW_IDX = TABLE_EVENT->SELECTEDROWINDEX
 COL_NAME = 'ZX_FGR1'
 CHANGING
 DATA = FGRVALUES_LINE-ZX_FGR1 .
 IF NOT FGRVALUES_LINE-ZX_FGR1 IS INITIAL.
* selektierte Firmengruppe übernehmen
 ZX_FGR1 = FGRVALUES_LINE-ZX_FGR1 .
 CALL METHOD NAVIGATION->SET_PARAMETER
 EXPORTING NAME = 'ZX_FGR1'
 VALUE = ZX_FGR1.
 ENDIF.
 CATCH CX_SY_CONVERSION_ERROR .
 ENDTRY.
works properly as it should be ...
An enormous Thanksgiving to you , Brian !!!!

Material Account Assignment Group, in Sales Order Mass Update

Sd Experts,
We just went live, our consultant updated Account assignment group at the material level but did not updated existing materials. When we caught the problem and updated exisisting materials there were some existing orders already created. Which now I am getting an account determination error due to this field being empty at the material level.
We have some sales orders that I need to update but they are just too many, currently I have been fixing them thru VF02, for to the material and update manually.
Does anyone has any idea how to mass update this field for all existing orders, to update "Account Assignment Group" field automatically
Your help will be greatly appreciated.

Hi
In Mass transaction choose object type as #BUS2032,after executing in the next screen from the tables choose#Sales Order Item Data, and from the fields choose#AcctAssgGr (MASSSDHE)-MASSSDHEAD_S-KTGRD, now execute to find fields Sales document and Sales Document item , here load all the Sales Orders for which the change is needed along with the items for which the changes are needed execute again to find the next screen with Sales Documet, Sales Document item and Account assignment which needed to be changed,now select the entire block enter new values in the Account assignment box in the above, click on the 'Carry out MAss change button ' and then save, it will take some time basing the change tobe carried and issues a log as to how many documents were changed
Hope this is clear,please do a test run before.

Mass updating a multi-valued field- to append the new value

I have a question on multi-valued fields:
I have store table with 5 multi-valued fields, say MLB, soccer, college FTBL, college Basketball, etc.
A store can have 4 MLBs, 2 soccer teams, and so on.
Say, there is a new MLB that came out called Mexico MLB team.
A user wanted to add this to 30 stores using a mass update. But remember the 30 stores can have totally different sets of values in the multi-valued fields.
How can I add this new value while still preserving the MLB teams values of each store record?
Does MDM not support this feature?
I am using SAP MDM SP6
An answer would be highly appreciated.
Thanks
Savi

Savi,
I assume you are defined these fields as multi-value lookup and linked to main table. In general, you can not because it will mess up and overwrite your multi-value entries for all of your 30 store records.
Here is something in MDM come in handy. It is following the same concept but design your model a little differently. If you model your multi-value fields into qualified lookup table, it will be easier and optimized to handle.
You can select all 30 records and mass-update with adding the new MLB entry into your Q-lookup table. Once you save, this mass-update action will respect all your diversity of each individual records with the new value added.
Hope this helps
If this answers your question, please kindly reward the points.

How to display multiple selected rows in a table inside a popup?

Hi,
I have a table on which multiple selection is enabled. I am able to get hold of multiple selected rows i.e. i am able to iterate over the selected row keys and print their values. Now, my problem is how to display the contents of all the selected rows in a popup? I get the details of only one row when I launch the popup.
Thanks
Karan

Hi,
Not confident if this works or not but just try it...
1. create a ViewLink between the same view Object.
The source and destination wil be the same Vo and the source and destination attribute will be the pk of both Vos.
2. Update the changes in Appln Module.
Open the AM and in DataModel tab .
select the Same VO from which you created table in the DataModel Listbox and select the VL in the "Avaible View Objects" List Box. Add under it(selected vo in datamodel listbox).
3. Refresh DataControl accordion.
4. in your jsff page drag and drop the child vo as a table..
See if it works
Regards,
Santosh.
