How add new column in analysis from two subject area

which is the right way to add a new column to an existing combined analysis from two subject areas?
if I add the new column first in my two combined queries, then I saw a new column in the results column panel, but this new column is empty and I can't edit its propreties (the button edit column doesn't work). I can't even save the modified analysis due to a "bad xml" errror.
if I try to first add a new column from the results panel and then in my combined queries, obiee says that new columns are not of the same type.
I suppose this is because the new column in results panel has no aggregation formula, unlike new columns in queries.
But I don't know how to change the properties of the new field in the results panel, with no subject area available.
I have to restart from a single subject area? possible?
In this case, there is a way to save/copy filters ecc. from the old analysis?
If anyone can help.
Thanks
Luc

When you are using union clause in analysis or combining with other subject area you suppose to have same number of columns and their datatypes with other analysis.
for datatype issues you can use cast in column expression in each analysis. If you want to add a column only from 1 analysis just add and in other analysis use dummy column with exp 0 or ''(for char) based on the datatype.
These you have to deal with each analysis.

How can I tell if signals from two devices are truly synchronised?

Hi there,
How does one check that signals from two devices (two separate devices in a single X-series chassis) that should be synchronised actually are? I am using a PXIe6361 and PXIe4331 on a PXIe-1073, with Labview 2001 SP1 64-bit. All devices are using the Sample Clock from the 4331 device, and an AI Start Trigger, so they should be synchronised.
I thought that writing the signal data to file and checking the time stamp for each column of data would be the most accurate, but I have been told that timestamps are software created and therefore don't reflect the actual time that the signals were acquired by the hardware. When I do this, the timestamps vary by up to 150ms which is larger than I expected.
If I set the x-axis of the waveform graphs (on the GUI) to "Time" then it appears that the first data sample is taken at different times for the two plots (one plot per device).
If I set the x-axis of the waveform graphs (on the GUI) to "Ignore time stamp" (so that the x-axis just starts from 0 rather than a date-time) then the first data point occurs at "0" for both graphs. However, I'm not sure that this reflects the actual alignment of the signal.
What is the best way to check if signals collected on different devices in the same chassis are actually synchronised?
Thanks,
Claire.

Hi Lynn,
Thanks for your help and for sending the demo.
I understand the concept of how the signals will look if they're not synchronised and your demo shows that nicely. I guess I have been perplexed by someone else telling me that the timestamps in the output file (and following from that I assume timestamps on a waveform graph) do not give an indication of whether signals are synchronised. The reason they gave for this was that the timestamps are manufactured by the software, not the DAQ hardware. They suggested that I put the setting "ignore waveform timestamps" on my waveform graphs, and then check that both signals come in at the same time (i.e. both start at zero), but I'm not convinced about this.
When I use an analog trigger, neither the timestamps in my output file or on the two waveform graphs are synchronised. If I don't use the trigger, then there is far less disparity in the timestamps in the output file. I've attached two output files here, and my VI.
This is my first attempt to synchronise a voltage module and a strain gauge module on an X-series chassis, so I want to make sure that I'm achieving the best synchronisation that I can, and the difference in behaviour with and without the trigger worries me.
Thanks,
Claire.

How to create Analysis from two different subject areas with diff models

Hello,
I have problem with create analysis from two different areas with two different models (Model Star and Snowflakes) build in BI Admin tools.
First Model A = Subject Area A have one fact tables (with measures) and three dimensions tables (Model Star)
Second Model B = Subject Area B have one fact table (no measures) and five dimensions tables (Model Snowflakes).
I'm looking solutions how I can give good results. In this case I can't use UNION, INTERSECT etc., because this models haven't the same number column and data type?
whether it is possible to do in OBIEE?
Please help me
Kind regard
robix

Hi
One thing to understand is that if your are imagining having two Subject Areas (SAs) displayed and then dragging columns from each into your Request without any preparation, then no, that can't be done. You would need to do a join in the BMM layer and expose the column from the second Subject Area in the presentation layer.
But if you indeed interested in UNION (or intersect) queries, then do this:
Build your first query in the first SA in the usual manner. Note the number of columns and the data types of each column.
Now at the bottom of the Criteria workspace, there is a button called "Combine with similar request." Click it.
Select your second SA. You will note that the outlines of the columns in your first query appear. This is to remind you that the number of columns in this second query must be the same as in the first. It also shows the data type of each column for the same reason.
Once you select your columns and your filters, click on result. (Oh, you will also need to decide what kind of combination you want -- click on the dropdown.) The result will be a new Request that has data from both SAs in the query and combined in the manner you select (union, intersect, etc.)
That should give you a start.

Column selection from 2 subject area

Whenever i m selecting column from two subject area then for a perticular column i m getting two values ........ i want only one value which is coming from one subject area as i m having no values for the same in the other subject area......How can i do tht

When you are using union clause in analysis or combining with other subject area you suppose to have same number of columns and their datatypes with other analysis.
for datatype issues you can use cast in column expression in each analysis. If you want to add a column only from 1 analysis just add and in other analysis use dummy column with exp 0 or ''(for char) based on the datatype.

How to add new column to COPA datasource?

Dear all,
It seems we have to delete the COPA datasource and regenerate it when we need add new column, if so,we should regenerate the initialIzation for the delta.
Beacause only the new delta data need have value for new column,so I do not want to reextract the historical data,do you have any solution?
Best regards
Simon

Hi Simon
You are correct, COPA DS need to be regenerated.
Initialize without Data Transfer might help you. But was thinking how do you manage the 'lost' delta in between the processes?
I m not sure about your flows i.e how data moves from PSA to cube but I think at least you should
Initialize the delta for the current fiscal year ( with Data Transfer) and then continue with delta.
Which type of COPA you are using? Account based or Cost Based? For Acc Based delta initialization starts from summarization level , so you also need to fill up summarization level at least for the current year.

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

Hi,
Use NVL or COALESCE:
NVL (col_a, col_b)
Returns col_a if col_a is not NULL; otherwise, it returns col_b.
Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

HI Pradeep,
Goto the transaction code (Change Report) GR32.
Give you library name and report name
And click on the column (application tool bar or F7) button then place the curser on the screen where you want column (please note you have to keep curser on the header section u2013Red column text) right click and insert element. Then you select formula as selection element and enter. You will get the enter formula box. Then you can type your formula and continue. This will add new column to the report.
How to enter formula: you can see the formula components in that id and description.
Id is columns that are present and description indicates explanation of that column.
Enter formula according your requirement.
Examples:
Enter formula screen:
ID : des
X001 amount
X002 pt000
X003 test
1. Enter formula as: ( X001 u2013 X002)
The above formula is for fist column u2013 second column.
2. ( ( X001 u2013 X002) / X003) * 100
First column u2013 second column and devide by third column after that multiple with 100.
Hope this will help you

How to add new columns in materialized view

We are using Oracle 10g Release2.
We need to add new columns to a prebuilt fast refresh materialized view. We want to add 4 new columns in this table and make them part of select statement in the materialized view. We can drop the view but we cannot do complete refresh after that because the paymentsInfo table has a creation_timestamp column which is populated by before row insert trigger with systimestamp. If we did the complete refresh, all values in this column shall be changed.
CREATE MATERIALIZED VIEW paymentsInfo
ON PREBUILT TABLE
REFRESH FAST
ON DEMAND
START WITH SYSDATE
NEXT SYSDATE+5/1440
WITH PRIMARY KEY
DISABLE QUERY REWRITE AS
SELECT PAYMENT_ID,BATCH_REFERENCE, TRANSACTION_REFERENCE, NO_OF_TRANSACTIONS, DEBIT_ACC_NUM,... from payment@dblink
I want to know is there any other way to add new columns without losing any changes from the master table.
Thanks.

There is no way to add new Columns to Materialized view. To add new columns, it has to be dropped and re-built again.
Extract from Oracle Documentaion:
Use the ALTER MATERIALIZED VIEW statement to modify an existing materialized view in one or more of the following ways:
To change its storage characteristics
To change its refresh method, mode, or time
To alter its structure so that it is a different type of materialized view
To enable or disable query rewrite
If you have a problem of Complete refresh, then It may be beneficial to get the backup of the MView; Drop and re-create it with modified definition; Restore the backup data leaving the new columns untouched (assuming they are to be kept as fetched from the Master site).
