Null Values from a Data Source

This is more of an implementation question than a
troubleshooting question. Also, since I've been unable to find any
documentation on this I was wondering if anyone has come across
this behavior or found a bug with it.
Yesterday I was working on an application to explore some
proof of concept aspects of Flex for an application I'm developing.
I started running into a problem with Flex Data Services throwing
back an 'Unknown Property: "clientaddress1"' error whenever I tried
to update data. It seemed that whenever I tried to update a record
in the database it would thrown the Unknown Property error. I spent
a good chunk of the day trying to figure out what was causing this
and finally gave up and called it a day.
This morning I was reassessing what the problem was and
trying to find the differences between my database and my code and
I stumbled upon the fact that I could add no records and modify
them without a problem, however if I tried to access an existing
record and update it I'd get the Unknown Property error.
I start analyzing the database and found that I'd configured
the database to use null values for empty values and the records
that I created with the database had null values, however, any of
the values inserted from Flex were inserted as blank values. As
matching my action script class as clientaddress1 = ""; So, upon
further testing I fould that Flex was not processing the null
values correctly, so that when it came back and rightly generated a
Conflict Error...and then called AcceptServer() it was unable to
find the clientaddress1 property of the class.
Also, if any of the properties in the database are null it
throws the same error. Basically it seems to have invalidated the
object just because one value was null. So if all of my values from
the DB are set to something and only one field is set to null it's
still throwing the error on the first alphabetical item of the
properties.
I can resolve the problem by not using null values in the
database, but...what sort of effect would this have on someone
working with a large legacy database that extensively uses nulls
for undefined values?
Also, if a Flex guru could explain the reasoning for this
happening I would greatly appreciate it!
Best regards,
Chris Maloney

I realize that I didn't clarify that I am using ColdFusion
for getting the data. This class was generated by the Create CFC
wizard in Flex Builder.

Report Builder Wizard and Parameter Creation with values from other data source e.g. data set or views for non-IT users or Business Analysts

Hi,
"Report Builder is a report authoring environment for business users who prefer to work in the Microsoft Office environment.
You work with one report at a time. You can modify a published report directly from a report server. You can quickly build a report by adding items from the Report Part Gallery provided by report designers from your organization." - As mentioned
on TechNet.
I wonder how a non-technical business analyst can use Report Builder 3 to create ad-hoc reports/analysis with list of parameters based on other data sets.
Do they need to learn TSQL or how to add and link parameter in Report Builder? then How they can add parameter into a report. Not sure what i am missing from whole idea behind Report builder then?
I have SQL Server 2012 STD and Report Builder 3.0 and want to train non-technical users to create reports as per their need without asking to IT department.
Everything seems simple and working except parameters with list of values e.g. Sales year List, Sales Month List, Gender etc. etc.
So how they can configure parameters based on Other data sets?
Workaround in my mind is to create a report with most of columns and add most frequent parameters based on other data sets and then non-technical user modify that report according to their needs but that way its still restricting users to
a set of defined reports?
I want functionality like "Excel Power view parameters" into report builder which is driven from source data and which is only available Excel 2013 onward which most of people don't have yet.
So how to use Report Builder. Any other thoughts or workaround or guide me the purpose of Report Builder, please let me know.
Many thanks and Kind Regards,

Hi Asam,
If we want to create a parameter depend on another dataset, we can additional create or add the dataset, embedded or shared, that has a query that contains query variables. Then use the option that “Get values from a
query” to get available values. For more details, please see:http://msdn.microsoft.com/en-us/library/dd283107.aspx
http://msdn.microsoft.com/en-us/library/dd220464.aspx
As to the Report Builder features, we can refer to the following articles:http://technet.microsoft.com/en-us/library/hh213578.aspx

How to eliminate null values from the data?

This query displays data for a project with approval & submission dates...I'm trying to eliminate records that have null values in Approval & submission date columns at the same time. But rather keep the records that have atleast one submission date or approval date?
SELECT distinct QP.QIP_id,
        Max(decode( Upper(QP.Status_CD), Upper('Approved') , Effective_date, null )) as Approved_date,
        Max( decode( Upper(QP.Status_CD), Upper('Submitted') , Effective_date, null ) ) as Submitted_date
         FROM Llp_Sys.Project_Status QP
         WHERE SYSDATE >= qp.effective_date
            AND (qp.terminated_date IS NULL OR SYSDATE < qp.terminated_date)

Infosource Fields with values from multiple Data Sources

Hi Experts,
My question is:
i have to load values of only few fields of 0LIS_11_VAHDR and few fields of 0LIS_11_VAITM into one infocube.
If i just create one infosource with those fields only in communication structure, but then i can assign only one data source at time, how to load values from another datasources at same time?
Can i do it using single infosurce? and if yes any guideline....
Thanks......

My dear, the problem is that even for the first solution (only one infosource) you have to manage two separate dataloads, since linking several datasources to one infosource means only that you can manage a unique communication structure, but different transfer rules/structures and, avove all, two different infopackages !
So, you have anyway to face the automation issue of your dataloading.
My suggestion has been more functional and conceptual than technical (for which I gave the same answer, that is, "you can do it"): you are not loading a master data source (the same object 0MATERIAL) with attributes, texts and hierarchies (and in this case it's obvious that you have to use one infosource); here you want to use the infosource dedicated to the header flow to load item info too (and you will have to use the same and unique update rules).
Again, no problem from a technical point of view, but I guess that someone who will look into your architecture, probably, will have something to say with this kind of choice !!!
Bye,
Roberto

To extract null Values from the source in Infopackage selections - Very Urg

Hi All,
I need to pull the data which has null values from source. I tried to write routine by giving l_t_range-low = '' , space. nothing is working.
Please guide me with sample code.
Very Urgent.
Regards
Mano

Hi Mario.
Assuming that you want to avoid uploading of records having
zero for a keyfigure:
Create a startroutine for transfer rules and add this coding:
DELETE DATAPAK WHERE VALUE = '0'.
OR
LOOP AT DATAPAK.
IF DATAPAK-VALUE = 0..
DELETE DATAPAK.
ENDIF.
ENDLOOP.
'VALUE' represents the fieldname in transferstructure
Please let me know if i misundersttod the issue.

Null values from DB2 cause problems

Hi,
I have another problem with database link to DB2 using IBM iSeries Access for Linux on 64 bit OEL5 with Oracle Database gateway and unixODBC 2.2.14.
DB link works. However, null values from DB2 cause problems. Date columns that are null on db2 return a date '30.11.0002', and character columns that are null return an error ORA-28528: Heterogeneous Services datatype conversion error.
isql returns correct results.
How can i fix this? Perhaps set some parameters for data conversion on the gateway?
Thank you.

If the driver is not fully ODBC level 3 compliant and misses functions, we're lost. But sometimes the drivers are ODBC level 3 compliant but miss the correct 64bit implementation. In those cases we can tell the gateway to use the 32bit ODBC level 3 standard by setting in the gateway init file:
HS_FDS_SQLLEN_INTERPRETATION=32

How to use a property from other data source

Scenario: we have 2 datasources, that each have their own set of records having different properties. What I need to do is grab 1 property that exists in all records of 1 of the datasources and display it in the records of the other datasource. There is 1 "common" property (called by different names) in the records of both Data Sources, that have the same value; so this property could be the link between those records even though they belong to 2 different Data Sources.
Here's a simple example:
Data Source " Department" has records that have the properties: 'Name', 'Age' and 'Nationality'.
Data Source "Staff" has records that have the properties:'Staff_name', 'Position'.
The 'Name' and 'Staff_name' have the same values, and can be used to link the 2 records.
I'd like to get the records in the 'Department' data souce to also contain the property 'Position" from the "Staff" datasource .
Is there a manipulator that can do this?
Thanks!
J

Thanks Pravin,
But I don't want to join all data from the 2 datasources - I just want one property from one data source to appear in the records of the other data source.

Data Extraction from Multiple data sources into a single Infoprovider

Hi Experts,
Can anyone send me links or examples on how to extract data from multiple data sources into 1 Cube/DSO.
Can anyone send me example scenarios for extracting data from 2 data sources into a single Cube/DSO.
Thanks
Kumar

Hi Ashok,
Check the following link from SAP help. Ths is probably what you are looking for.
[ Multiple data sources into single infoprovider|http://help.sap.com/saphelp_nw70/helpdata/en/e3/e60138fede083de10000009b38f8cf/frameset.htm]
Data from multiple data sources which are logically related and technicall have the same key can be combined into single record.
For example, if you have Sales order item and sales order item status .
These both have the same key - sales order and item and are logically related.
The Sales order item - provides information on Sales order item - material , price, quantity, plant etc.
The item status - povides information on delivery status, billing status, rejection status....
These are two different data sources 2LIS_!1_VAITM ad 2LIS_11_VASTI.
In case you have few master data attributes coming from different systems ie tow data sources in different systems say completely defines your master data. Then you could use a DSO or infoobject to combine the records.
If you want to see aggregated data you use a cube.
ie say you want to analyzae the customer revenue on a particular material and a particular project.
The project details would come from Project syatem and Sales details fom sales flow.
The data is then combined in the DSO with key cutomer and sales area say.
Then it is aggregated at cube level...by not using sales order in the cube model...so all sales order of the same customer would add while loading the cube.. to give direct customer spend values for your sales area at aggregated level.
Hope this helps,
Best regards,
Sunmit.

Combining Data into one Cube from two Data-sources..

Dear Experts,
I am pulling data from two data sources and trying to combine in one Info-Cube. The data are like
Data-Source 01
1. GUID --Common
2.Document No ( User Entry)
3.Dist. Channel
4.Transaction Type
5.Date and Quantity
Data-Source 02
1.GUID -- Common
2.Billing Document ( If User drill down according to Document No , Billing Document should come in the report )
3.Billing date
4.Net Value
Out of the datas , The GUID is common between the 2 data-sources. I was thinking that, tha data will take according to its place and If i select the Document No in Report, it will atomatically fetch all the data like Tran type, dist ch, Billing Document No , Billing date.. .
The problem is , in the report Tha data is not coming as I was thinking.
And Another problem is , In future I need to create a Multiprovider between the above mentioned Info-cube and One ODS. And DOCUMENT NO is common in Cube and ODS.
Please Suggest,
How can I proceed for the following requirement.
Thanks,
Sanjana

Hi Sanjana,
In your case cube will create a problem because it will have multiple records . For example :
Data-Source 01 :
1. GUID -- 101
2.Document No - 999
3.Dist. Channel - DL
4.Transaction Type - GPRO
5.Date and Quantity - 20.02.2011 & 20
Data-Source 02
1.GUID -- 101
2.Billing Document - 6000
3.Billing date - 03.03.2011
4.Net Value - 500
Your cube will have 2 records . And your requirement is to show above two records in 1 record in the report .
Why dont you make an ODS in between , where you can put GUID as the Key field and rest all the fields as data fields. Create 2 transformations to this DSO from the 2 datasources . And let it get updated one by one . Your DSO will have 1 record only . Now either you do reporting on this DSO or take the data to the cube .
Hope the above reply was helpful.

Status from 0CRM_SALES_ACT_1 Data Source

hi
We are extracting BWSTONESYS0 BW Status from 0CRM_SALES_ACT_1 Data source. It gives data in 10 , 20 , 30 format and we looking for any data source to load the text for same.
Regards,
Monika

Hi John
I dont think that kind of mapping we need to do mannually. Becasue in our case we also enhanced this datasource with lots of indicator types of fields that are coming dynamically and not from any table, and we didnt maintain any settings in TCODE BWA1 but still values are coming fine. Please check during final update in the table are you not clearing the work area?
have you enhanced other fields also in which value is coming or this is the only fields enhanced in the datasource?

Regarding combining data from 2 data sources

Hi All,
I want to represent data from two data sources. Orders (2lis_11_vaitm) and billing (2lis_13_vditm). We have in common Plant, Material customer etc. I want the query to be executed based on Billing date. However, when I am executing the report based on billing date, I am getting all orders as 0 and I am only getting Inv qty and value. The reason for this is there is no billing date in 2lis_11_vaitm. So, how to merge these two data sources??

How to use value from one data set in other data set SQL select.

Hello all, i have one data set, and i need to get value from that data set into other data set. Something like '?' but without input. I will try to explain it with screenshots:

If both tables come from the same data source, join the two tables in one data set rather than two as shown. If they are from different data sources, use a 'join data set'

Need help Take out the null values from the ResultSet and Create a XML file

hi,
I wrote something which connects to Database and gets the ResultSet. From that ResultSet I am creating
a XML file. IN my program these are the main two classes Frame1 and ResultSetToXML. ResultSetToXML which
takes ResultSet & Boolean value in its constructor. I am passing the ResultSet and Boolean value
from Frame1 class. I am passing the boolean value to get the null values from the ResultSet and then add those
null values to XML File. When i run the program it works alright and adds the null and not null values to
the file. But when i pass the boolean value to take out the null values it would not take it out and adds
the null and not null values.
Please look at the code i am posing. I am showing step by step where its not adding the null values.
Any help is always appreciated.

How can I delete null values from List Item?

Hi Friends,
I used List item for field job_Type, I entered values in List item at design time through property pallet. When I run form I will see null values in this List Item.
How can I remove these null values from the List?
Best regards,
Shahzad

Dear Shahzad,
It can be removed by adding the following code in the When-new-Form-Instance.
Set_item_property('List name', required, property_true);
:block_name.list_name := <put your default value here>; (If you didn't oput the default value, then you will get some problem and the cursor may not navigate away from the list).
