Data Adaptor - Sample Code (DerbyDataAdaptor)

Hello,
I am trying to understand the DerbyDataAdaptor which is mentioned in the the Oracle Policy Automation Developers Guide. The guide states that their are some files stored @
examples\interview-engine\data-adaptor\src\create_db.sql
examples/interview-engine/data-adaptor
examples\rulebases\compiled\Parents and Children.zip
I cannot locate all these files, I am looking at the location C:\Program files (x86)\Oracle\Policy Modelling\examples. Their is no interview engine folder nor rulebases folder.
However I can find Parents and Children.zip but it is not at the location specified above,I'm not sure if it is the same example.
Please can you help me locate these files?
And if you can provide any help you think may be useful for the DerbyDataAdapter that would be most helpful.
Many Thanks

Hi,
Have now found where these are located, it's in the Java Runtime Zip file, thanks.

Sample code on how to populate data in DropDownListbox

Hi all
i am new to the webdynpro for java.
i have one UI element called DropDownListBox and i want to populate some desired values to the dropdown list box.
what are the different ways are there to populate data in DropDownList box.
for example i have city as dropdownlist box and i want to populate some values in drop downlistbox like bangalore,hyderabad,chennai and delhi,
can you pls send the sample code on the same?
Regards
Suresh Babu

Hi,
If you want to retrieve the city names then you can use the standard tables in R/3.
We have countries list in T500T. Like this we have table for the cities also.
Or
You can manually populate a table and bind this table to the list box.
Please check out this link -

Sample code converting binary data to image file

Hi experts ,
I need sample code to convert binary data (bytes) in to an image file.
any help will be appreciated.
Thanks and Regards,
Naresh

You need to show binary and decimal? Or now just decimal?
If binary and decimal, you can right click on your indicator and choose "Display Format...". If you select the Advanced Editing Mode, you can make soft interesting display formats. This includes showing the same value in mulitple ways in the indicator. Try something like "%032b - %d" for the format string.

Sample code in Update Rule to restrict data selection?

We used to restrict data selection in InfoPackage data selection, e.g., for company code range when loading data from a source system (e.g. EBP which is similar to R3), but somehow the company code range we set in InfoPackage data selection not working and we found actually it occurs on the source system side when running RSA3 on EBP side and input the company code range in RSA3 selection section, but still it extracts data beyond the company code range. We don't understand why EBP data selection doesn't work, then we consider in update rule on BW to set the company code range. We know in update rule, we can select Start Routine, formula, or routine to set the company code range. But we would be appreciated if experts here can recommend which one is the most efficient to load data fast for data load performance reason and would be appreicated if you can let us know the sample code!
Thanks in advance!

If you expect a useful answer here, you'll have to narrow your thread(s) to one specific
issue. Posting a (virtually) complete application specification is far too broad and
comprehensive for any one thread in these forums.
Pick *one* aspect of this project and describe what problems you're having writing the code.
Post a new thread for each specific problem.
As posted, you appear to be hoping to find code already completely written for this project.
Most sample code illustrates *one* task, not a dozen. If you aren't able or willing to do
the lion's share of the coding yourself, you may have to consider contracting a developer.

Sample code for routine

Hi all,
This is what I want to achieve. I have an attribute for an IO, but the values for that has to be decided at the transfer structure level. I want to write a routine in the transfer rules to populate the field.
I have another field that gets populated from R/3. I need to write a routine which would take this value and see if it falls in the range and have to decide the value and populate.
I have gl_account coming in, and in the routine I need to take that value of the gl_account and see if it falls in the range of 1 5000 or 6700 - 8130 if so assign a + sign and if not assign a sign to the new field.
Any sample code would be appreciated and rewarded.
Thanks,
Sri

Routine sample code for reading 2 fields from existing DSO

Hi Gurus,
I am a monkey when it comes to write ABAP code. I have one DSO-A where we store accounting info of purchading (from DS 2lis_02_acc) and one DSO-B getting data from 2lis_02_scl data source.
We need to write a rountine to read DSO-A for G/L account and populate DSO-B G/L account field.
Please provide me the sample code for this.
Warm Regards,
Anil

Hi anil,
Create a local table this is type of you source,
Data : LV_table TYPE XXXX
use the select statement to read the table of DSO .You have to use th active table for the dso that you want to read data from.
Select xxxfieldxxx FROM /BIC/A..........50
into lv_table where
filed name of of scheule line probably order no and item no .
<soruce-fields>-IOBELN = IOBELN
and <source-fields>-IOBELP = IOBELP.
Checke the techinal name i am not sure about it. It will be something like that.
Cheers mate

A sample code to check records of a system table?

hi ABAP4 experts,
We are pretty new at ABAP4. We would be appreciated if you can provide a sample code to check how many records and calculate a total amount for a specific field, e.g., DMBTR in a system table, e.g., BSEG. Note: there is no any selection for this table BSEG, we just want to get the total record count in this table and also the total amount for a specific field e.g. DMBTR in this table.
Do we have to use an internal table to transfer all the records of BSEG into the internal table to get the result?
We will give you reward points!

Hi Kevin,
Using SUM directly in SQL will NOT work for table BSEG because BSEG is pool table. You will get an ABAP error.
"Aggregate functions and the addition DISTINCT are not supported in field lists for pooled and cluster tables".
You need an internal table to transfer all data from BSEG and perform calculation for count and sum.
Concerning about performance running perhaps you can code something like this.

Default data adaptor error when deploying a war file in weblogic

Hi All,
Newbie here with a few questions regarding the deployment of OPA 10.1. Really hoping you guys can help...
1) I'm attempting to deploy an unexploded web-determinations.war file on WebLogic. Thanks to this forum I've got past the issues of "rulebase directory not found" etc. However, i'm now faced with an issue which I can't find any info on. Please see below.
3672074 [[ACTIVE] ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'] WARN com.or

I've got the following entry in the application.properties file too...
# Default XDS data adaptor file path
#xds.file.path =data
From what we can see we believe the code is getting a null pointer because of the following method in the WebDeterminationsServletContext class.
public String resolveFullPath(String path)
File f = new File(path);
return f.isAbsolute() ? f.getAbsolutePath() : this.servletContext.getRealPath(path);
We believe the getRealPath(path), highlighted in red, is returning null. Any ideas how we can resolve this?
2) The second issue I'm facing is with regards the plugins.libraries property in the application.properties file. I've got the entry as
plugin.libraries =DataAdaptor.DA;
which should point to our customised data adaptor. However I'm getting the following error.
4242994 [[ACTIVE] ExecuteThread: '2' for queue: 'weblogic.kernel.Default (self-tuning)'] WARN com.or
acle.determinations.web.platform.servlet.WebDeterminationsServletContext - Can not find class: Data

acle.determinations.interview.engine.local.LocalInterviewEngine - Can not find class: DataAdaptor.D
A
3) Also, does anyone know if it's possible to deploy a web-determinations.war file containing additional internal application code? What we're attempting to do is deliver a single war file which not only holds the web determination code but also all the code for an application which wraps the OWD within it. At present this just isn't working. I'm not sure what the conflict is exactly. The only way i seem to be able to get this working is by deploying the code in two seperate war files.
Any help on these issues would be greaty appreciated.
Thanks,
Taj

(2) is being caused because your data adaptor plugin is not installed properly. The jar that contains your plugin needs to go in the WEB-INF/lib directory and you must specify the fully qualified class name in the plugin.libraries property of the application.properties file.
If you haven't provided a custom data adaptor, Web Determinations will configure and attach the default one for use instead, which is file based. If you are deploying to WebLogic as an unxeploded war, you must configure the directory the default data directory the plugin will uses by specifying an absolute path that your instance of Web Determinations has read/write permissions to in the xds.file.path property of the application.properties file. In your case (1) is basically being caused by (2) since if the your data adaptor was loaded correctly the default one wouldn't load at all.
As for (3) yes it's likely possible, provided you don't have library conflicts. How it's done really depends on what these additional customisations consist of.

Badi ME_PROCESS_REQ_CUST Sample Code required for changing the values

Dear Friends,
I am new to the Badi technology. We would like to populate/change the standard field values, (Purchasing group) during Purchase Requisition creation/change.
Method --> PROCESS_ITEM.
I tried the following code, but system blnaks out all the field values entered during PR creation.
Appreciate, if you could provide me some sample code which can be of help.

Sample code----
METHOD if_ex_me_process_req_cust~process_item .
DATA: k_mereqitem          TYPE mereq_item,
        om_data              type mereq_item,
        om_datax             type mereq_itemx,
    k_mereqitem = im_item->get_data( ).
    check im_count = 1.
    if k_mereqitem-bsart = 'ST' and
       k_mereqitem-loekz = ' '.
    om_data-pstyp = '5'. " assign default item category code
    om_data-bnfpo = k_mereqitem-bnfpo.
    om_data-WERKS = k_mereqitem-WERKS.
    om_datax-pstyp = 'X'.
    call method im_item->set_datax
         exporting im_datax = om_datax.
    call method im_item->set_data
         exporting im_data = om_data.
    endif.
ENDMETHOD.

Hi Kumar,
i have not a special solution for your case, but i use this BADI with great effort
As my comments in example are in german lg. i explain in short words what i do:
X) define data
1) select data from base item
1a) header-data
1b) item data (easy)
1c) accounting data
2+3) check field values, post warning message + mostly change values + sometimes set cursor focus on field
Have a look and give me some points if my example increased your BADI knowledge
regards
Jörg
