Comparing data b/w biw and oltp

hi
Could some one can halp me how to compare data between biw and oltp system.which has been extracted.
Thank for your precious time spent to help me in learning.
Thanks,
Jagadeesh

Jagadish,
It is not always all extracted data are coming from one standard table and comparison is easy. most of the time from multiple tables. There are couple of things you can do.
1. If you know any R3 functionals you can inquire about reports available that produce the same kind of column groupings.
2. If no one exists or do not get much help from them, and if you have SQ01 access in R3 you can create a query to bring the same columns fromcorresponding tables (This is a harder because you need access and need to findout from where data is coming from though info is available in help.sap.com).
3. more practical would be select a small subset of data, with right filters in your selection columns of the info package and extract data, at the same time use the same selection in RSA3 (R3 side) to extract data and compare. This should tell you whether what you have in R3 is matching with the extracted data.
4. After your transformations you can compare the same with your info provider (cube or ODS) contents as well.
hope this helps,
Award points if useful.

What's wrong with my code for comparing date retreived from db and sysdate?

Hi all,
I need to retrive date from the DB and compare it to system date.i have posted the code below.i get java.sql.SQL Exception:Io exception:Socket closed.
What's wrong with the code?please help me.Thanks in advance.
public boolean date() throws IOException, SQLException {
Connection con1;
long millis = System.currentTimeMillis();
Timestamp timestamp = new java.sql.Timestamp(millis);
ResultSet rs4 = null;
try
Class.forName("oracle.jdbc.driver.OracleDriver");
con = DriverManager.getConnection(
"jdbc:oracle:thin:@abc:1605:xyz",
"cdf", "cdf");
Statement stmt_exp = con.createStatement();
rs4 = stmt_exp.executeQuery("SELECT DATE FROM TABLE_NAME")
while (rs4.next()) {
Timestamp timestamp2 = rs4.getTimestamp("expire_date");
con1.close();
catch (Exception e)
e.printStackTrace();
finally
//ResultSet rs4 = null;
//Timestamp timestamp2;
Timestamp timestamp2 = rs4.getTimestamp("expire_date");
if (timestamp2.compareTo(timestamp) < 0) //sysdate < exp date
return true;
} else {
return false;
}

Didn't you understand what BalusC said? You're closing the connection and then trying to use the ResultSet. The ResultSet will be closed when you close the connection so you can't use it anymore.
You should close the connection last thing in your code, probably in a finally. And after you close your ResultSet and Statement.

Compare Date Modified on OneDrive and LocalStorageFile

I can't find an easy way to compare two files
When uploading (CreateBackgroundUploadAsync) file from LocalStorage to Onedrive the Modified Date kind of appearing is changed since it become a place holder and not the real file.
How can I compare Date Modified (updated_time is NOT the real Modifed Date) and also I would not like to download file back to either the phone or Desktop as it good be lengthy.
I should only download/upload files which are different. Basically just to synchronize files.
Thanks

Hi,
Based on my research, the Date Modified changed could be due to corrupt Update Sequence Number Journal. The USN Journal is a feature of NTFS which maintains a record of changes made to the volume.
You could try to refer to article below to check if it could resolve the issue.

How to compare data between two tables?

Hi,
My team is trying to develop a SAP data migration tool (DMT) using ABAP.
One of the functionalities in the DMT is to validate the data in the staging area against the loaded SAP data.
The tables in the stagin area are customer tables (i.e. user-defined tables starting with Y, Z).
How do I compare the data in the staging area against data that are loaded into SAP tables? Are there some built-in SAP functions to do this? Or, are there some better ways of doing this (e.g. instead of comparing against data in the SAP tables, we compare with some INTERNAL tables)?
Any help would be greatly appreciated, thanks!

Hi Kian,
Use <b>SCMP</b> transaction to compare data between two tables and you can not use this for comparing internal tables.
Thanks,
Vinay

How to compare delivery date in schedule lines and PGI in outbound delivery

Hi,
I want to create a report to monitor and compare different dates in sales and delivery process.
One of my key figure is the comparison between date confirmed to the customer, that I can find in the schedule line of the sales order, and the actual goods issue date from the outbound delivery.
But I can't succeed in making the link between delivery and schedule lines, means between LIKP and VBEP.
Would you have any idea?
Thank you.

It seems there's no exact (table) connection / link between delivery item and schedule line item.
Those who were searching for this thing (link / connection between delivery item and schedule line) were recommended to use FM "RV_SCHEDULE_CHECK_DELIVERIES".
This FM calculates the delivered quantity for each schedule line, so it makes link between the delivery item and schedule lines - however if you check the code it's quite sophisticated...
(if you put a breakpoint in the FM and display a SO in VA03, you can check how the parameters have to be populated with data).

Need help in using SQL in a jsp file to compare date and time

hi every one,
Actually I am doing a project using JSP. I need to compare a date field in the database (MS Acess) to the current system date and time. I have to do this in a select statement.
I have alredy defined a variable of type Date in the JSP file and I am comparing this variable to the date in the database through a select statemant.
Here is what I am doing
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-mm-dd hh:mm:ss");
java.util.Date today = new java.util.Date();
String myDate=sdf.format(today);
query = "SELECT Car_ID, Model_ID, Year, Ext_Color, Price from Cars where EDate <= "+myDate+" ;";
EDate is the feild in the database and it's format is (5/12/2008 5:29:47 PM) it is of type Date/Time in MS Acess.
when I execute the query it gives the following error
SQL error:java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression 'EDate <= 2008-10-16 08:10:07'.
I hope any one can help me with that error and answer my question, I've tried too many things but nothing helps
Thanks in advance :-)

Hi,
When the comparision is needed to be done with the current date , we don't need to send in Java
Date then format it and compare with MS Acess Date.
In MS Access we have Date() function which will give you the current date.
So you can try rewriting your query as following :
query = "SELECT Car_ID, Model_ID, Year, Ext_Color, Price from Cars where EDate <= Date() ;"; ---------------------
Hope this helps.
Thanks

How to compare date and time together

Hi,
How to compare Date and Time together?
For example in a database table there are two fields rundate and runtime. I want to compare these two with perticular date and time in the program. Like, I want to pull all the records where the records's date and time are less than a perticular date and time in the program.
Hope the question is clear...
Thanks.
Kavita

Hi Kavita
There is no as such Date and Time Comparision FM in Standard SAP But You can define your own like this
<b>FUNCTION ZAV4_COMPAREDATETIME.
""Lokale Schnittstelle:
*" IMPORTING
*"     REFERENCE(DATE1) TYPE DATS
*"     REFERENCE(TIME1) TYPE TIMS
*"     REFERENCE(DATE2) TYPE DATS
*"     REFERENCE(TIME2) TYPE TIMS
*" EXPORTING
*"     VALUE(TWOISMORETOPICAL) TYPE C
twoismoretopical = ''.
if date2 > date1.
    twoismoretopical = 'X'.
else.
     if date2 = date1 and time2 > time1.
       twoismoretopical = 'X'.
     endif.
endif.
ENDFUNCTION.</b>

Function module for comparing dates and times

Hi,
I have a date and time stamp in one filed for example as below:
20070125183045
(the first 8 are date in YYYYMMDD format, the next 6 is time in HHMMSS format). Now I want to compare this value to another such value in terms of date and time. First I want to compare dates and then times. Do you know any function module that can serve this purpose?
Thanks very much!

You can compare these using the function module DURATION_DETERMINE. This fuction will give you the difference, and it can be in a view different units, such as the difference in days, months, etc.
Funciton module takes in Start date and time and end date and time.

Compare data and return the different columns

Good Afternoon,
I am trying to compare the data in two tables and return only the columns and data where there is a difference.
I have a compare script which checks every column in the two tables against each other, but as there are 200 columns in the tables it is tricky to see which column has a difference.
So in my result set if coulum N is the differenct I would only want to return column N from both tables in the result set.
I hope that this all makes sense?.

Easiest way is to use tablediff utility for checking difference between tables

Compare dates between 2 different rows and columns

I'm having problems figuring this out. Here is an example table:
What I need to be able to find is any records where the Discontinue_Date is greater than the Effective_Date on the next row for a given Customer ID and Part_ID. This is a customer pricing table so the Discontinue_Date of row 53 for example should never
be greater than the Effective_Date of row 54130, these are the records I'm looking to find. So I'm looking for a SELECT query that would look for any records where this is true. Obviously the last Discontinue_Date row for a Customer_ID will not
have a next row so I wouldn't want to return that.
Let me know if anyone has any ideas or if more clarification is needed, I've been struggling with how to get started on this!!
Thanks very much in advance!
JIM

>> I'm having problems figuring this out. Here is an example table: <<
NO! Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data
should use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums. You pasted a colored picture that we have to transcribe into DDL to do your job for you. But you also do not know basic terminology!
Rows are not records, since tables are sets, there is no “next row” concept, rows do not have physical row numbers, etc. Your mindset is still in a spreadsheet and not RDBMS.

Why not prevent bad data instead of trying to kludge and report it after the fact?
Consider this self-reference trick to prevent gaps in a timeline of events:
CREATE TABLE Events
(event_id CHAR(10) NOT NULL,
previous_event_end_date DATE NOT NULL
CONSTRAINT Chained_Dates
REFERENCES Events (event_end_date),
event_start_date DATE NOT NULL,
event_end_date DATE UNIQUE, -- null means event in progress
PRIMARY KEY (event_id, event_start_date),
CONSTRAINT Event_Order_Valid
CHECK (event_start_date <= event_end_date),
CONSTRAINT Chained_Dates
CHECK (DATEADD(DAY, 1, previous_event_end_date) = event_start_date).
<< other stuff for this event >>
-- disable the Chained_Dates constraint
ALTER TABLE Events NOCHECK CONSTRAINT Chained_Dates
-- insert a starter row
INSERT INTO Events(event_id, previous_event_end_date, event_start_date, event_end_date)
VALUES ('Foo Fest', '2010-01-01', '2010-01-02', '2010-01-05');
-- enable the constraint in the table
ALTER TABLE Events CHECK CONSTRAINT Chained_Dates
-- this works
INSERT INTO Events(event_id, previous_event_end_date, event_start_date, event_end_date)
VALUES ('Glob Week', '2010-01-05', '2010-01-06', '2010-01-10');
-- this fails
INSERT INTO Events(event_id, previous_event_end_date, event_start_date, event_end_date)
VALUES ('Snoob', '2010-01-09', '2010-01-11', '2010-01-15');
Since you did not write DDL for us, you can use this idiom to get a working schema.

Reconciliation to verify data in R/3 and BW

Hi Experts,
Can any one explain me how we will maintain reconciliation to verify the data in SAP R/3 and SAP BW are same or not after the data loads. Please explain all the sources that we have.
Thanks in advance
Mallik

For Unit Test, you don't need to reconcile all the records. So, I take a couple of selections. Using these, go to RSA3 in R/3 and extract the data and take sub-totals in Excel.
Now, go to Info Provider in BW, and using same selections, download the data in BW or BEx and take sub-totals again and compare both.
If the extractor is generic extractor based on View/Tables, you can go one additional step and get data from SE16 in R/3 to make sure RSA3 and Tables also match.
For Business Content extractor, its a little difficult is do this step because most of them are Function Modules.
This should be enough as long as your selections are good.
You can compare the data from RSA3. Run RSA3 and save the data in a file and then compare with BW.
You can compare the PSA data with R/3 to check whether your data transport is correct.But its very much important the end result (with data in Data Targets ex.Infocube...) should be reconciled with the R/3 data to check your update and transfer rules are working fine.
The second part is too tricky since you cannot directly compare the reports while the formats and grouping are different.
You can execute the reports in R/3 and apply the Update and transfer conversions (at least for random records) then reconcile with the BW data.
Take a look on the note: 543188
"How to Reconcile Data Between SAP Source Systems and SAP NetWeaver BI"
The Data Reconciliation procedure is still in the SAP action item for the future release.
But we can reconcile the data by extracting the reports and compare with the query output in Excel sheet.
Please check for a tool "Excel Compare" in google which is really useful in comparing excel files.

By this method you can compare your infocube data with PSA ones...clearly, every changes in R/3 (due to user exit or, above all, BW-specific standard logic) is not taken into account...if you want to consider also this part (back-end), there is no std method and it depends from every specific flow!
also check in service.sap.com/bi

One way is to define Remote Cube on the R3 data source and create multiprovider on BW with the Remote Cube and the BW target. Subtract the KF on R3 from the KF in BW - anything not 0 becomes an exception.
Sometimes the source on R3 is not as straight forward and we have had ABAP developers create summary table on R3 to compare to BW.
Actually one to one Data comparison between R/3 and BW is done during Integration Test phase. During this time we need to sit with R/3 team and work closely because they know exactly the numbers in R/3 side and which tables Data resides and all. After loading Data same data in to BW we compare the numbers between R/3 BW. If both the teams feel there is some data missing then we start the analysis. As a first stem we will see in the extractors then BW side during transformation like transfer and update rules.

verifying the data which is coming from R/3 to BW system. That is called as Reconciliation.
That process is done with v lookup functionality.

Compare data in R/3 with data in a BW Cube after the daily delta loads

Hi Friends,
How can I compare data in R/3 with data in a BW Cube after the daily delta loads? Are there any standard procedures for checking them or matching the number of records?

Hi Sunil,
If you want to check the records daily instead of checking the data in R/3 manually ......
You can try this...
If you have staging DSO(level 1) that means whatever data is in source system load it to Staging DSO without any routines or any modifications.
Now load this DSO data to Cube or DSO(level 2) as per your requirement with routines etc.
Now Staging DSO contains Source system data.
Now the level 2 Cube or DSO contains BW data with some modifications.
Now create a Multiprovider based on level 1 and level 2 data targets.
Now create a report on which keyfigures you want to test the data.
In Multiprovider there is a field called 0infoprovider in data packet dimension.
you can drag this infoprovider to the columns and restict your keyfigures with level 1 and level 2 data targets.
In the first column you can see the level 1 DSO data ( source system data),in the 2nd column you can see the BW data.
Now create a formula which gives the diffrence b/n level 1 and level2.
that is R/3 data - BW data.
If the diffrence is zero both R/3 and BW data are same.
if the diffrence is not eqaul to zero check whether any routine is there or not.
