GREATEST Function question

I have a simple question, but I am not sure about it.
Say that rank3 has the best score of 99 and it wins, how do I know
which column it was ? Is there a way to also in addition to bringing
back the winning rank value, to also bring back which column that came from ?
select customer_id, GREATEST(rank1, rank2, rank3, rank4, rank5) Winning_Rank
from table;

Question has a version dependent answer.
You need to provide your four digit version always in your request, and you shouldn't need to be asked to provide it.
My initial reply is it will be difficult due to the non-normalized structure of the table.

SD & FI BI functional Questions

Hi Experts,
I need to ask some questions to customer on SD & FI functional related questions for BI Analytical reports..
Already cutomer implemented Data ware house Informatica with congnos reporting tool.
right now they want to implement BI.
please any one can share on what type functional questions could ask the customer.
Advance Thanks,
Bala.

Hi,
A few more pointers.
Start with Reports. What the client is using. What he is expecting.
If he got existing reports map the fields with Business Content BW Fields. Go to Business content and make a list of queries which are delivered from SAP. Explain them the KPI's. This should be good to start with. Also check the Tcodes they use.
Look for DataSources that get data from theses Tcode's.
Project Preparation (Initial stuff -- Do a conceptual review after this phase requirements gathering)
Collect requirement thru interviews with Business teams /Core users / Information Leaders.
Study & analyze KPI's (key figures) of Business process.
Identify the measurement criteria's (Characteristics).
Understand the Drill down requirements if any.
Understand the Business process data flow if any.
Identify the needs for data staging layers in BW (i. e need for ODS if any)
Understand the system landscape.
Prepare Final Requirements Documents in the form of Functional Specifications containing:
Report Owners, Data flow, KPI's, measurement criteria's, Report format along with drilldown requirements.
Hope this helps.
Thanks,

Sumifs function question

Hi, Everyone, I have a function question of Sumifs, here a sample as follows,
=SUMIFS(Budget :: E4:E14,Budget :: C4:C14,"=5003677000",Budget :: B4:B14,OR("=Transit","=Drawing cash")), according to the logic, I think like this, but it's wrong. So how to insert the OR function to the Sumifs function? May someone find the mistake in the function?
Thank you.
Alex

I think you would actually do a sum of simifs, i.e. Sumif(....."Transit") + Sumif(....."Drawing Cash")
Basically if you have two sumifs that differ in only one condition that would be treated like an OR in SQL, then make one Sumif for each unique set of conditions and add them up

OIC: Functional Question(11.5.10)

Hi All,
I would like to know answer for the following functional question in Oracle 11.5.10 Incentive Compensation Application(OIC). I would greatly appreciate if you anyone can reply for this.
1. Question on Foreign currency exchange rates:
We know that OIC cannot handle foreign currency exchange rates. Since all of our offer letters to the Sales guys are in local currency what we end up doing is picking an exchange rate on July 1st every year and converting them to US $. What I’m wondering is why couldn’t we just set them up in OIC in their local currency, without converting them?
Is that possible? OIC can handle this?
2. In OIC, Can I enter a DUMMY Acoount Executive (since we are not going to credit any single person in the Primary Account Executive role) that bookings could be credited to in order to ensure they roll up to the appropriate manager?
a) Is that possible?
b) Does this DUMMY Acoount Executive should be part of the HR Employee setups as well?, In OIC should we need to load the transaction for DUMMY Account
Executive so that credit will get rolled up to approriate managers based on the Group hiearchy setups?
Thanks,
Johnson

Yes

You do not need to set up the dummy resource as employee. All you need is to create as OTHER type of resource and add that resource to group.
Hope this helps.

Incremental updates on collections/full schedule - Functional question

Hi everyone,
At a customer of mine we have the following set-up:
Almost all applications are deployed User Based
Collections are used for targetting the applications
Incremental updates are enabled on practically all collections which deploy applications
For the moment this setup is active for 498 collections (out of 714 collections).
Since it's not advised and Microsoft recommends to only have incremental updates active for 200 collections, I would like to change this setup by means of POSH. I have just finished writing it, but I still have a functional question:
Which schedule time would be best to activate for the collections? Keep the standard value to update collection every 7 days?
When would you activate "incremental updates"? Device collections with required software for faster deployment time?
I only foresee the following "downside":
We have a lot of applications who are available to "all domain users". When the AD-account is created, it will sync with SCCM and will receive their deployements. But by changing the update schedule to, let's say, 7 days.. They wouldn't be able
to see and install these applications if the collections haven't been updated yet?
Thanks for the insight with your experience!
Kr,
Sven

Wow Jörgen, thanks for this information! This was something I haven't read about. Will keep this in mind.
In your blog, you mention that you use this tool to keep track of performance issues. When do you feel that there are too many collections which have incremental updates enabled (by using the tool)?
The last weeks/months, we have a lot of issues during OSD. We have collections to which the TS is deployed.
In orchestrator we have a runbook to add workstations to SCCM + add workstation to collection + update membership of collection. But the update takes from 5 minutes to 40 minutes.. So this is the main issue that we have..
@Andrew: Thanks for your contribution! I believe you are speaking of "Global Conditions"? I haven't used it either, but I thought that this had some downsides.. For instance, we target most of the applications "Used Based" (since MS is
moving to user centric deployment). So if I target the application to the "all users" collection and create a "global condition" to only install when user is a member of a specific AD-group (for instance: Skype), then the user still sees
"skype" in the application catalog and will have an error upon installing it when he is not a member of the skype AD-group.
Maybe this is completely wrong what I'm saying.. Just did some brainstorming with collegues but haven't found the time to play with it in a test environment. @Jörgen: Please enlighten us if I'm wrong.

SIMPLE question about GREATEST FUNCTION

select greatest('2005-1-1', '2004-1-1') from dual will return 2005-1-1
select greatest('2005-1-1', '2004-1-1', '') from dual will return nothing, I want it to return 2005-1-1
Any work around?

First thing I tried was to clarify in my head that the last option had a space.
so I tried the following...
select greatest('2005-1-1', '2004-1-1') from dual got 2005-1-1
select greatest('2005-1-1', '2004-1-1', '') from dual got BLANK
select greatest('2005-1-1', '2004-1-1', ' ') from dual got 2005-1-1....
So you need to put the space in between the ticks.

Performance issue and functional question regarding updates on tables

A person at my site wrote some code to update a custom field on the MARC table that was being copied from the MARA table. Here is what I would have expected to see as the code. Assume that both sets of code have a parameter called p_werks which is the plant in question.
data : commit_count type i.
select matnr zfield from mara into (wa_marc-matnr, wa_marc-zfield).
update marc set zfield = wa_marc-zfield
     where werks = p_werks and matnr = wa_matnr.
commit work and wait.
endselect.
I would have committed every 200 rows instead of every one row, but here's the actual code and my question isn't around the commits but something else. In this case an internal table was built with two elements - MATNR and WERKS - could have done that above too, but that's not my question.

Here's the question - why did this person enqueue and dequeue explicit locks like this ? They claimed it was to prevent issues - what issues ??? Is there something special about updating tables that we don't know about ? We've actually seen it where the system runs out of these ENQUEUE locks.
Before you all go off the deep end and ask why not just do the update, keep in mind that you don't want to update a million + rows and then do a commit either - that locks up the entire table!

The ENQUEUE lock insure that another program called by another user will not update the data at the same time, so preventing database coherence to be lost. In fact, another user on a SAP correct transaction, has read the record and locked it, so when it will be updated your modifications will be lost, also you could override modifications made by another user in another luw.
You cannot use a COMMIT WORK in a SELECT - ENDSELECT, because COMMIT WORK will close each and every opened database cursor, so your first idea would dump after the first update. (so the internal table is mandatory)
Go through some documentation like [Updates in the R/3 System (BC-CST-UP)|http://help.sap.com/printdocu/core/Print46c/en/data/pdf/BCCSTUP/BCCSTUP_PT.pdf]

Basic Functionality Questions - Is a computer required to serve content, etc?

I'm sorry if these are no-brainers. I ask them because I thought I had understood how an AppleTV worked, and had planned on buying one, until a friend who owns one insisted that the device functions differently than I had understood it to. I think he's wrong, but I was hoping you guys could clear up a few things for me.
1) Does an AppleTV require that I have another device (iPad, Computer running iTunes, etc) on and connected to watch content purchased from my iTunes account, or will it stream directly from the 'net?
2) If I've converted video content from a source other than the iTunes store (for example, ripped a DVD and imported it to my computer's iTunes library) can I stream it to my AppleTV (assuming the source computer is on?)
3) Assuming #2 is true, the content in question must be served by a computer - ie, I can't move it to the cloud, and viewing it is dependant on having my computer on and running. Is this correct?
Thanks in advance guys!

1- it will stream purchased items such as TV shows, not music unless you have the iTunes match subscription. You need another device if you want to do "home sharing" (share your iTunes library with other devices, If you have already bought movies, music, etc.)
2- You will have to import it to iTunes if you want to see it on your ATV.
3- Yes, you need to have a computer act as a server with iTunes running all the time...

An MM functional question

Hi all,
I have a question like
Report has to extract the details related to invoices and payments to Vendors for the list of Purchase Orders for goods and services procured which are selected in the input screen. The report should calculate the time in days, from when the Purchase Order (services/goods) is released and till the time payment is made to the Vendor. It should take into account the invoice document posted and the payment terms for the Vendor in order to get the correct due date. It should give the difference in terms of days between invoice due date and payment date and indicate whether the payment was done before or on the due date.
Iam confused with the flow becz iam not able to relate the ekbe (po history) and the BSIS , BSAK table to get the vendor data as the ekbe (belnr shows the material document No) and the the BSIS and BSAK shows the (A/c document No).
can any one help me in this this is a urgent requirement.
Thanks,
SriRatna

SriRatna,
Pl let me know your email address so that I can email you the material prepared by me, this will give you complete overview of getting the data from different tables and their relationship based on the scenarios we commonly face in all different functional modules.

Oracle XE Functionality Question

Hello,
I am here trying to get the opinion of Oracle XE users regarding a project I am considering.
Currently, my employer uses Access databases, with the master on a corporate server, and 4 slaves on local servers at warehouses. At each warehouse, there are probably 10-30 new records created per day by 2 or 3 users at each location, which get synced to the main at the end of each day. Any changes that need to be made at the corporate level get synced and sent on to the warehouse as needed.
Besides sending out these changes, the corporate office will also add 40-50 records per day. Information is also pulled for reports- seemingly pretty normal Access tasks. I don't know the exact stats, but each backed up copy of the DB is less than 100mb, so it's not a huge system. (It's for keeping track of inbound and outbound shipments, carriers, locations, etc.) There are probably 6 users at this location.
So the question I have is, would XE have the functionality to at least cover these tasks, and possibly more. (What more is at the moment, I do not know.) My own preference would be to grow into Oracle DB, but if the Access functions cannot be replicated, we would probably move on to something else, so I thought I'd ask for current user experience.
Thanks for your time.

Hi,
I think application running on XE and Apex suits for your current situation perfectly.
And if system gets bigger you can get license of "full" Oracle database and upgrade.
Using single database server and web application everything is "online" and you do not need transfer any data end of day.
XE 10G database comes with Apex 2.1. That Apex version is quite old.
But you can upgrade Apex to latest one.
http://www.oracle.com/technetwork/developer-tools/apex/overview/index.html
There is coming XE 11G that ship latest Apex and features that 10G do not have.
You can also save more user data to XE 11G. But I assume XE 10G 4GB limit is enough for you.

I did find this blog that is actually running on XE and Apex
http://www.apexninjas.com/blog/f?p=100:1:1421570076381594::::P1_ARTICLE:
I think you can not run blog application on MS Access =)
Also I think Oracle database have much more features than Access, specially with Apex.

thanks, can this be combined into one query ?Do you mean without a sub-query?
Why? What's wrong with a sub-query?
If uisng a sub-query is the clearest and most efficient way to get the results you want, why wouldn't you want to use a sub-query?
Suppose there was a way, that involved some other technique. How would we know that you didn't object to that technique as well?
At any rate, I don't see how to do it without a sub-query. Analytic functions are computed after the WHERE clause is applied. If you want to use the results of an analytic function in a WHERE clause (as here, we want to use the results of the analytic COUNT function in a WHERE clause), then you have to compute the analytic function separately, in another (sub-) query.

Greatest Function...

Hi,
I havea query like this:
select trunc(GREATEST(MAX(TRAVEL_START),
                        MAX(TRAVEL_STOP),
                        MAX(LABOR_START),
                        MAX(LABOR_STOP)))
from t1the columns are combinaton such that user can enter travel_start and travel_stop combination OR labor_start and labor_stop combination or both or none of them...
Now,
the query fails when user inputs any one of the combination.. so for eg. user enters labor_start and labor_stop but does not enter Travel start and stop combinaton(i.e. null is stored in travel start/stop) the greatest returns null instead of returning greatest from labor_start/stop combinaton.
What should be done to rectify this..
thx

I missed the requirement that the output should be null when all 4 columns are null, so I added a NULLIF function to achieve the desired result. The example now becomes:

Another MAX() function question...

Help was provided earlier for a question I had regarding use of the MAX function... This also pertains to that. I have two tables, employee and movie. I want to find the name of the employee who has entered the most amount of movies into our database. The query I have come up with so far (it's a little messy) is:
SQL> select firstname, max(m) from (select firstname, count(enteredby) m from em
ployee, movie where enteredby = id group by firstname) group by firstname;
FIRSTNAME MAX(M)
Peter 6
Swanson 5
Kevin 7
Beverly 3
So I have this table returned, now in this case I want to be able to select from this subquery the first name "Kevin", since he has entered in the most movies. In my head this seems so easy, "Grab the firstname of the person whose max(m) is the largest", but I am just having trouble getting this thought translated into a proper query!

You can always do
SELECT firstname
FROM (SELECT firstname, RANK() OVER (ORDER BY max_m) rnk
          FROM (<<your query>>))
WHERE rnk = 1Note that you'll need to alias the MAX(m) result first. You could also do
SELECT firstname
FROM (
SELECT firstname, RANK() OVER( ORDER BY cnt) rnk
FROM (SELECT firstname, COUNT(enteredby) cnt
          FROM employee e, movie m
        WHERE enteredby = id
        GROUP BY firstname)
WHERE rnk = 1From a style standpoint, I would suggest that you get in the habit of aliasing your tables in your FROM clause and putting that alias on every column name to make it clear which table a particular column was selected from.
I would also suggest that you come up with a column naming convention that caused the same value to be named the same (or similar) thing in different tables. Joining an ID column from one table to an ENTEREDBY, for example, would be a non-obvious bit of logic. It probably makes more sense to have an EMPLOYEE_ID and an ENTERED_EMPLOYEE_ID column.
