Developing JSP using SQLJ

Does anyone know how to develop JSP using SQLJ? This chapter is not availabe in the developer's guide. And which one is a better solution, JSP + BC4J or SQLJ?

I would stick with the JDK 1.1.8 in JDeveloper 3.0. SQLJ and JDBC do not yet support JDK 1.2 (they will in Oracle 8.1.6 and JDeveloper 3.1... not sure about OAS 4.0.9, but I would suspect so).

Summary Detail Screens in one window using PanelSplitter

Hi All,
I'm using JDev 11, ADF BC, Windows XP(OS), IE 7.
I would like to have a summary screen in first facet and detailed screen in the second facet.
The dynamic search should be enabled in the summary screen. Onclick of a value in a options displayed in the summary,
the detailed form for that screen should open in the second facet, that form should be editable.
Assistance is appreciated...
Thanks in advance...

hi,
When i've used SelectOneCheckBox the concept of PPR works between facets(first and second).
But when i used a table and try to show the values of one column in the selected row from the table it doesn't display the value.
I've tried converting the value to String and then displaying it, but that doesn't work either.
Now i would like to know is there a way to make a particular column variables as CommandLink and on click of
that open the respective page in the Second facet.

Use of revision no,revision date field in bom header details screen

Hi all,
Please let me know use of revision no,revision date field(customer fields tab) in bom header details screen.I tried with F1 ,no information.
Thanks
Sukumar

Dear,
In standard SAP in BOM header overview there are 4 tabs.
Quants/Long text.
Further Data
Admin Data
Doc Assignment.
I think Customer fields tab may be customized based on client's requirement.
I Know about revision level. It Identifies the change status of a material.
The revision level can be uniquely assigned to changes made using a change number.
Hope this helps. Correct me if i my understanding of the problem is wrong.
Thanks and Regds

Custom property not displaying at folder creation or Details screen

Hello everyone
I have created a custom boolean property that I need to have displayed both at folder creation and in the Details screen of a folder after it's created. The property is in the default namespace, and is in the Custom group. I have created a properties file for the label and created the necessary meta data extension. The folder validity pattern is " / " and the Resource Type listed is "normalct" so that it's active for folders only.
Then I went to Property Groups and listed my new property in the Group Items field of the Custom group. The Custom group is a part of "all_groups" so that group is displayed both when a new folder is created in KM and when the Details screen of a folder is displayed.
However, my custom property isn't displaying under the Custom tab when I go to create a new KM folder, nor when I view the Details screen of an existing folder. What configuration am I missing? Do I have to develop a custom property renderer for each new property I need to create? I was hoping I could achieve this result with configuration changes only, but I must be missing something.
Any help would be greatly appreciated and rewarded.
Thanks in advance,
Fallon

Hi Fallon,
actualy, if you want this property to be displayed only for folders and not for documents, you don't need to specify the resource type for folders. Setting "/" or "/**" for "Folder Validity Patterns" and "" (empty) for "Document Validity Patterns" should be enough.
If you sill experience problems, you have to check all settings, for example with the settings suggested in this <a href="https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/2654">weblog</a>. If you use the "default" Property Group in the property settings, you don't have to enter the Property ID in a special Property Structure Group that in turn is integrated in the all_groups Property Structure Group.
Hope this helps,
Robert

Detail screen for row level locking

Hi All ,
I have developed row level locking for a table , Next requirment is to display the details of each row i another screen when the user click on each row .And if the row which is clicked for display is geyout in first screen then it should be grey in details screen also .If the row is editable in the first screen then it should be in change mode in details screen .
I appreciate the help and support .
please provide the answer as soon as possbile .....
Thanks,
NJ

Yes, if a process holds many row level locks on a table, those locks by default can be escalated to partition locks, and, if necessary, table locks. Unless you are getting and holding many locks on a given table, this will not happen.
You say you are exporting data. If all you are doing is selecting from the table (not updating, deleting or inserting data) and you are using the read committed transaction isolation level, you would only hold a lock on a row for the small fraction
of a second when you are actually reading it. So you will never have large numbers of locks at one time. If you are doing large numbers of updates, inserts, or deletes in a singletransaction or if you are doing large numbers of selects in a single
transaction with the isolation level set to repeatable read or serializable, then it is possible to get enough locks to cause SQL server to escalate to partition or table locks. This is normally a good thing (that's the reason Microsoft made it the default).
To many locks eats up memory.
However, if you determine this is causing you a problem and you do not want the locks on a particular table ever escalated, you can use the ALTER TABLE SET (LOCK_ESCALATION = DISABLE) command to prevent most cases of lock escalation on a table by table basis.
See BOL for a description of the ALTER TABLE command. However, I would recommend you not use this unless you have determined that lock escalation is causing you problems. It is very easy to make things worse, not better by doing this.

How to prevent error message for material description in MDG material detail screen, when user click on check action

Dear Experts,
I have a requirement for making material description as non mandetory in change request view of mdg material screen.
I have done that using field usage in get data method of feeder classes, but still message is displaying.
This message 'Material description is mandatory is displaying with check action only, but not with save or submit after i anhance field property as not mandetory.
How to prevent error message for material description in MDG material detail screen, when user click on check action.
Thanks
Sukumar

Hello Sukumar
In IMG activity "Configure Properties of Change Request Step", you can completely deactivate the reuse area checks (but will then loose all other checks of the backend business logic as well).
You can also set the error severity of the checks from Error to Warning (per CR type, not per check).
Or you provide a default value for the material description, e.g. by implementing the BAdI USMD_RULE_SERVICE.

SAP Work Manager customization - adding a new field to equipment details screen (Syclo Agentry)

Hi Experts,
I am trying to add a field (NAME1) on the Equipment details screen under work orders in work manager 5.3 application.
I have performed the following steps, but I am getting an error while connecting to the application.
1) Create extension for Equipment class to add a new field.
2) added the new field (Name1) as the property to the standard object Equipment.
3) Added the field on the screen.
4) Added the field (name1) to the complex table ctEquipment.
5) Added the JAR file to Agentry.ini file.
6) Changed the Class mapping for parameter "Equipment" under group "SAPOBJECT" to point it to the custom (Extended) class.
7) Changed the class mapping for complex table parameter "ctEquipment" under group "CT_SAPOBJECT" to point it to the custom class.
8) after publishing the changes and re-starting the server, I get following error.
the log file generated (message.log) also has the same description.
What am I missing here? Any help would be really appreciated.

Hi Emanuel,
Thanks for looking into this issue.
I have performed the following steps as suggested by you, still it doesn't seem to work and gives the same error.
Below are the changes done on the ECC Side.
1) Copied the standard equipment class /SYCLO_CL_PM_EQUIPMENT1_DO to custom class ZSYCLO_CL_PM_EQUIPMENT1_DO. Changes made in the GET Method to get custom equipment related data
2) Modified the standard equipment structure /SYCLO/PM_EQUI_STR by adding one custom field
3) Configured this custom class as the object handler in the equipment mobile data object
4) Configured this custom class as the object handler for the equipment complex table
5) We are still using the standard BAPI Wrapper itself for getting the equipment data and the added field is reflected in the BAPI Wrapper table parameter
Is there something we are missing?

How to display user define value in list screen from detail screen

Hello Experts
I am working on task in which i have to display the user define value on list screen. like i have one list list screen which have one button for add..once i click on add which navigate to detail screen and detail screen has two fields one for ID AND other for name and detail screen has one button for save once i put value for id and name and click on save button which will navigate to previous list screen and those values which should be display on list screen.
Regards:
Sumit

Hi Sumit,
To navigate to the Master page on button click , you need some thing like,
oSplitApp.toMaster("masterpage_id");
to understand the navigation for Master/Detail page , have a look at,
http://help.sap.com/saphelp_uiaddon10/helpdata/en/df/adb6b7247e4826b0fcde472b029840/content.htm
Also to pass value from Detail page to Master page, you can use a Global variable to store your values on click of the Save button. For eg. You may have a global JS file which both Master and Detail page can access like App.Js, Application.JS etc.
After navigating to the Master page, you can read the Global variables and show it on your Master page.

Field label of a CUF in SC item basic detail screen

Hello all
We're on SRM 5.0 with SRM Server 4.0 SP08.
I added a customer field (CUF) in SC item by adding and activating an append structure in INCL_EEW_PD_ITEM_CSF_SC and in INCL_EEW_PD_ITEM_CSF. I also implemented BAdI BBP_CUF_BADI_2 in order to set this CUF to visible / read only.
When adding an item to my SC and navigating to the item basic details screen, the CUF is showing up properly EXCEPT that its label on the left hand side corresponds to the technical field name in my append structure... and it shows up in capital letters as well.
Is there any possibility to influence the labeling of CUF's ? I mean without the need of a modification?
Any useful hints appreciated!
Renaud

Hi
As Disha told, Using SE11 transaction, you need to make changes to Custom Data Element (Short/Medium/Lon Description) you are using in the Append Structure of the INCL (Includes) and make the changes there to reflect on the Shopping cart screen.
Let me know incase you need any other details.

Custom field in limit order Details screen

hi all,
i am trying to add cuf.field called purch. Group which is not present in limit orders details -> Basic data tab. one of the structure has the value of purchasing group so i didn't include any custom field in shopping cart items structure "CI_BBP_ITEM_SC". just i want to map this value to the custom screen field for display only .when i see in the SAP GUI it is visible but not in the ITS Screen. do i need to change the internet service file if so Pls help me..
helpfull answers will be rewarded...
Thanks,
Henry

Hi Henry,
You can use the 'Append structure' concept to add custom screen field and use one of the BAPIs to assign values to it. The value could come from the shopping cart item structure.
You dont need to change the ITS for it.
Thanks,
Waheed

Problem with primary key violation in master-detail screens

Hi,
I found a problem/bug in master-detail screens in which the PK of the detail table consist of the PK of the master table and an additional column. E.g. a manually entered sequence 'in parent'.
I will use the following simple scenario to explain the problem (it's easy to reproduce):
PROJECT table
# id (PK)
* name
PROJECT REQUIREMENTS table
# prj_id (PK)
# sequence_id (PK)
* description
Just create the BC EO, VO and AM and set both display properties of the prj_id attribute of the project requirements VO to hidden.
Create a new screen in the application structure file in which you can select a project (table-form layout) and display the details (table layout) on the same page.
With this basic setup you can generate the app to enter, update and delete projects and their requirements.
The problem occurs if you have a project with a least 1 requirements stored in the database and you try to enter a second requirement with an existing sequence_id within the project. This is an use case in which a end-user enters wrong data.
So assume we have in the database:
prj_id sequence_id description
====== =========== ===========
1 1 req1
and the end-user enters (prj_id is entered automatically as it's not displayed):
1 1 req2 >> user should have enterd sequence_id 2...
Step 1. If you try to save an error will be displayed:
JBO-25013: Too many objects match the primary key oracle.jbo.Key[227300 1 ].
And the sequnece_id is emptied automatically.
Step 2. So the end-user re-enters the sequence_id but fills in 2 now and saves.
Another error is displayed: JBO-27014 sequence_id in AppModule is required
How strange? Everything is filled in already.
Step 3. If you just hit save again (without changing anything) you got a transaction completed successfully.
I checked the logfiles and noticed an exception during after executing step 2.
oracle.jbo.AttrValException: JBO-27014: Attribute SequenceId in AppModule.ProjectRequirementsView2 is required at oracle.jbo.AttrValException.<init>(AttrValException.java) at oracle.jbo.server.JboMandatoryAttributesValidator.validate(JboMandatoryAttributesValidator.java) at oracle.jbo.server.EntityDefImpl.validate(EntityDefImpl.java:2051) at oracle.jbo.server.EntityImpl.validateEntity(EntityImpl.java:1373) at mypackage1.ProjectRequirementsImpl.validateEntity(JwTekeningnummerImpl.java:273) at oracle.jbo.server.EntityImpl.validate(EntityImpl.java:1508) at oracle.jbo.server.EntityImpl.validateChildren(EntityImpl.java:1232) at oracle.jbo.server.EntityImpl.validateEntity(EntityImpl.java:1339) at oracle.jbo.server.EntityImpl.validate(EntityImpl.java:1508) at oracle.jbo.server.DBTransactionImpl.validate(DBTransactionImpl.java:3965) at oracle.adf.model.bc4j.DCJboDataControl.validate(DCJboDataControl.java:967) at oracle.adf.model.binding.DCBindingContainer.validateInputValues(DCBindingContainer.java:1683) at oracle.jheadstart.view.adfuix.JhsInitModelListener.validateInputValues(JhsInitModelListener.java:193) at oracle.jheadstart.view.adfuix.JhsInitModelListener._doModelUpdate(JhsInitModelListener.java:166) at oracle.jheadstart.view.adfuix.JhsInitModelListener.eventStarted(JhsInitModelListener.java:92) at oracle.cabo.servlet.AbstractPageBroker._fireUIXRequestEvent(Unknown Source) at oracle.cabo.servlet.AbstractPageBroker.handleRequest(Unknown Source) at oracle.cabo.servlet.ui.BaseUIPageBroker.handleRequest(Unknown Source) at oracle.adf.controller.struts.actions.StrutsUixLifecycle$NonRenderingPageBroker.handleRequest(StrutsUixLifecycle.java:325) at oracle.cabo.servlet.PageBrokerHandler.handleRequest(Unknown Source) at oracle.adf.controller.struts.actions.StrutsUixLifecycle._runUixController(StrutsUixLifecycle.java:215) at oracle.adf.controller.struts.actions.StrutsUixLifecycle.processUpdateModel(StrutsUixLifecycle.java:106) at oracle.jheadstart.controller.strutsadf.action.JhsStrutsUixLifecycle.processUpdateModel(JhsStrutsUixLifecycle.java:140) at oracle.adf.controller.struts.actions.DataAction.processUpdateModel(DataAction.java:317) at oracle.jheadstart.controller.strutsadf.action.JhsDataAction.processUpdateModel(JhsDataAction.java:622) at oracle.adf.controller.struts.actions.DataAction.processUpdateModel(DataAction.java:508) at oracle.adf.controller.lifecycle.PageLifecycle.handleLifecycle(PageLifecycle.java:112) at oracle.adf.controller.struts.actions.StrutsUixLifecycle.handleLifecycle(StrutsUixLifecycle.java:70) at oracle.adf.controller.struts.actions.DataAction.handleLifecycle(DataAction.java:223) at oracle.jheadstart.controller.strutsadf.action.JhsDataAction.handleLifecycle(JhsDataAction.java:389) at oracle.adf.controller.struts.actions.DataAction.execute(DataAction.java:155) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:484) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:274) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1485) at oracle.jheadstart.controller.strutsadf.JhsActionServlet.process(JhsActionServlet.java:127) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:527) at javax.servlet.http.HttpServlet.service(HttpServlet.java:765) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at com.evermind.server.http.ResourceFilterChain.doFilter(ResourceFilterChain.java:65) at oracle.security.jazn.oc4j.JAZNFilter.doFilter(Unknown Source) at com.evermind.server.http.EvermindFilterChain.doFilter(EvermindFilterChain.java:16) at oracle.adf.model.servlet.ADFBindingFilter.doFilter(ADFBindingFilter.java:239) at com.evermind.server.http.EvermindFilterChain.doFilter(EvermindFilterChain.java:20) at oracle.adf.model.servlet.ADFBindingFilter.doFilter(ADFBindingFilter.java:239) at com.evermind.server.http.EvermindFilterChain.doFilter(EvermindFilterChain.java:20) at oracle.jheadstart.controller.CharacterEncodingFilter.doFilter(CharacterEncodingFilter.java) at com.evermind.server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java:645) at com.evermind.server.http.ServletRequestDispatcher.forwardInternal(ServletRequestDispatcher.java:322) at com.evermind.server.http.HttpRequestHandler.processRequest(HttpRequestHandler.java:790) at com.evermind.server.http.HttpRequestHandler.run(HttpRequestHandler.java:270) at com.evermind.server.http.HttpRequestHandler.run(HttpRequestHandler.java:112) at com.evermind.util.ReleasableResourcePooledExecutor$MyWorker.run(ReleasableResourcePooledExecutor.java:192) at java.lang.Thread.run(Thread.java:534)
This also explains why I got a error message within the application at step 2, but not an expected error message!
From the logfile I can see something is going wrong in the oracle.jbo.server.EntityImpl.validateEntity method.
To get more insight what was goning on I overridden the validateEntity method in my VO Impl class:
protected void validateEntity()
System.out.println("MARCEL>> sequenceId=" + getSequenceId());
System.out.println("MARCEL>> description=" + getDescription());
super.validateEntity();
In step 1 the validateEntity is not called.
In step 2 the sequeceId = null (and description = reg2)
I expected the sequeceId to be 2 now as I entered this. Furthermore if I look at the (JhsActionServlet) request parameters in the log, I can see that the value of the sequenceId was 2. I guess something is going wrong at this point in converting the request parametes to the EO.
In step 3 the sequeceId = 2 (as expected)
Note that I'm using the evaluation copy version of JHeadstart 10.1.2.
If this was patched in any later build, could you please tell which changes I have to make to the JHS sources to solve this problem.
Regards,
Marcel

Marcel,
I cannot reproduce this in version 10.1.2.2. We did not "fix" this, although changes in the runtime might have fixed this "silently". I suggest you upgrade to 10.1.2.2 and see whether you still get the error.

Total column not changed between header & detailed screen

I have a report with header data contains contracts information and detailed data contains orders, debit credit memo related to the contracts. I write the report using CL_SALV_TABLE to display contract value, usage in full ALV_GRID. When I double click on a contract line, it will go to the second screen to show all orders related to that contract. The second screen with orders information will be in a screen on a container with all standard function ( Export list to Excel, Word format etc..), sort, total and sub total) and a push button to go back to first screen.
The report works fine but when I am on the second screen, I total and sub total the amount on that screen in order to check with total value in header record and it total up correctly by currency.
But when I go back to the first screen, select a different contract record, double click on the line to get to the order info screen, all order data display correctly except that the total column still show amount from the previous detailed screen. If I select the column again and click the total, it will total correctly. I did refresh the data in the screen before go back to first screen but it does not solve the problem.
DOES ANYONE HAVE A SIMILAR SYMPTON LIKE THIS?
Thanks for your advice.
On the order detailed screen, I create a container with screen 100 and write PAI, PBO like this:
Screen 100:
process before output.
module status_0100.
module load_data_to_control. "Load usage data to screen
process after input.
module user_command_0100.
module status_0100 output.
set pf-status 'PF100'.
set titlebar 'T100'.
endmodule.
module load_data_to_control output.
if gr_cont is not bound.
 create object gr_cont
 exporting
 container_name = 'CONTAINER_100'
 exceptions
 others = 1.
 if sy-subrc <> 0.
 message a052(zvn) with
 ' No container object found'.
 endif.
 try.
 cl_salv_table=>factory(
 exporting
 list_display = list_display
 r_container = gr_cont
 container_name =
 importing
 r_salv_table = gr_alv_2
 changing
 t_table = gt_orders
 catch cx_salv_msg into gr_error.
 endtry.
 perform set_functions. " Set all standard function in screen 100
 perform set_column_order using gr_alv_2. "Set column format, display
 perform handle_events. "Register events for selection mode & user commands
 Display order screen 0100
 gr_alv_2->display( ).
else.
 gr_alv_2->refresh( ).
endif.
module user_command_0100 input.
data: wa_d type gt_dtab,
 ls_contract type vbeln,
 ls_order type vbeln,
 ls_invoice type vbeln,
 ls_belnr type belnr_d,
 ls_row type char10.
data: l_text type char128.
 case sy-ucomm.
 when 'RETURN' or 'BACK' or 'EXIT' or 'CANCEL'.
*... refresh the table in order to see the new data
 gr_alv_2->refresh( ).
 leave to screen 0.
 when others.
endcase.
endmodule. " USER_COMMAND_0100 INPUT

Hi ,
When you are using the CL_SALV_TABLE, what is the use of screen 100. Better populate the evnts table in CL_SALV_TABLE
