Split and Joins?

Hi,
Could anyone explain the split and Join with simple scenarios?
I understand that a split is geared towards movement from one activity to more than one activities, and vice-versa for a Join! But, is there a 'correlation' between the Or-split, And-Split and Or-join, And-join?
Thanks experts,
Kosh!

Abasolutely, and split means both workitems should be evaluated on and join, default is Or split.
But, make sure with your need, if you really need some approvals where there are lets say 5 possible approvers on a particular work item, then you do not really need to use split join, just use iterate and break it up on one's approval

Workflow Components : how to use SPLIT and JOIN ?

Dear all,
Because a Transition does not have any return of result, do you know how to use SPLIT and JOIN components ?
<activity name='"xyz">
<Transition to='act1'>
</Transition>
<Transition to='act2'>
</Transition>
</activity>
In this above example, the second transition towards act2 is never called (i.e. there is no condition for the first transition) because there is no return of result for the first transition.
Unfortunately, I didn't find any documentation about the SPLIT and JOIN workflow components. Do you have some information about these components ? How to use them ?
Thanks a lot.

<activity name='"xyz" andSplit='true'>
<Transition to='act1'>
</Transition>
<Transition to='act2'>
</Transition>
</activity>
The "andSplit='true'" will cause it transition to both act1 and act1.

Split and join

I have a split - join circuit. I have three seperate activities in three seperate roles inside the split-join. Since I am using the same presentation form, the changes made in the presentation form for one activity are not reflected back into the other activities inside the split -join.
How can one reflect these changes in all activities inside the split-join?

Here's how you can see the same information across all branches of a split/join circuit.
Change the properties of the Split (click "Advanced") and uncheck the "Generated copies" checkbox.

I set up family sharing wrong, so i left family sharing and joined the right way agin but an error occurred and now it tells me I'll have to wait 364 days to rejoin again! How can I reset my account so I can use it again?

WWhen I set up family sharing i did it with me as family organizer, but as my spouse is the organizer I had to leave the "family" I created and join his. But while setting it up an error occurred, and the screen went blank. Now I tried to join his family sharing again, and my phone keeps telling me I can't because accounts can only join families twice a year.
I Don't really want to wait 364 days from now, is there a way in which I can reset my accoint so I can join family sharing again?
Apple support doesn't have a solution for me yet!
KInd regards

This morning I looked at my family sharing account again an IT WORKS NOW! Think Apple has done a reset to my account, though I'm not exactly sure why! So I hope it works for you guys as well!

Multiple rows Converge to Single row and join

Hi Folks,
I am facing a tricky challenge to join a table with multiple rows and converge into a single row (based on ID, period) and join with another table to get a single row. Let me explain.
Table 1: DTL_TABLE (id, period, course, names, title, type)
1 2010 mat john null null
1 2010 mat jim null null
1 2010 cam null officer null
1 2010 cam null Prof null
1 2010 phy null null Inclass
1 2010 phy null null Online
Join with
Table 2: ID_TABLE(id, period, Loc, Dept, Code)
1 2010 nj 101 CC.
Output format (id, period, course, names, title, type, Loc, Dept, Code)
result : 1 2010 mat,cam,phy john,jim officer,prof inclass,online nj 101 CC
I have created all the DDLs and DMLs if that help. Kindly let me know if a Join SQL query is possible.

I used the wrong password for my belkin wifi. Now that I know the correct password I can not get pass the unable to connect or join message. I have turned off all the options such as wifi and join and also put my touch to sleep.. but nothing seems to work

I used the wrong password to join my new belkin wifi. Now that I have the correct password, I can not get the to the join screen with the space to type in the password. I continue to get the unable to join message. I have put the touch to sleep and I have turned on and off the wifi and join options on the Network screen page. Does anyone know how to get pass this block of the wrong password to a new page that will allow me to type in the correct password. I see there is a option that asks if I want to reset the network settings.. is that what I should do? and what does it erase when I do that? Thanks for any input anyone has.

Yes. Reset network settings. Head to Settings -> General -> Reset and tap Reset Network Settings.

StringTokenizer vs. split and empty strings -- some clarification please?

Hi everybody,
I posted a question that was sort of similar to this once, asking if it was best to convert any StringTokenizers to calls to split when parsing strings, but this one is a little different. I rarely use split, because if there are consecutive delimiters, it gives empty strings in the array it returns, which I don't want. On the other hand, I know StringTokenizer is slower, but it doesn't give empty strings with consecutive delimiters. I would use split much more often if there was a way to use it and not have to check every array element to make sure it isn't the empty string. I think I may have misunderstood the javadoc to some extent--could anyone explain to me why split causes empty strings and StringTokenizer doesn't?
Thanks,
Jezzica85

Because they are different?
Tokenizers are designed to return tokens, whereas split is simply splitting the String up into bits. They have different purposes
and uses to be honest. I believe the results of previous discussions of this have indicated that Tokenizers are slightly (very
slightly and not really meaningfully) faster and tokenizers do have the option of return delimiters as well which can be useful
and is a functionality not present in just a straight split.
However. split and regex in general are newer additions to the Java platform and they do have some advantages. The most
obvious being that you cannot use a tokenizer to split up values where the delimiter is multiple characters and you can with
split.
So in general the advice given to you was good, because split gives you more flexibility down the road. If you don't want
the empty strings then yes just read them and throw them away.

Mid month Relieving and joining

Hi All,
Relieving and joining during mid of the month are not getting pro- rated.
System is able to pro-rate the salary for any unpaid absence but not for relieving and joining cases.
What is that I am missing? Please tell
Regards
Astha

Hi,
Relieving in the middle of the month:
Please check the payroll status infotype - 0003 of the relieved employee and mark the relieving date at field "Run Payroll upto" field.
Joining in the middle of the month:
Please check the date specification infotype - 0041 of the employee joined in the middle of the month (i.e hiring date) and mark it in that infotype.
After completing above process. Run the payroll.
Lets wait, what other experts says for this.

View and join Table

Hi,
what is the differnce between view and join table

Hi,
There are 4 types of views in SAP.
Database View - To club more than one table
Projection View - To hide fields in one table
Maintenance View - To maintain database records in table
Help View - To provide help for a fields (Same functionality as Search help. This is outdated)
View are improves performance in the following aspects
1. If you want to use more than two table in 'JOIN' condition better to use Views . It will improves performance of a program
2. If you want to use mutiple FOR ALL ENTRIES clause, better to club all SELECT statement in a view.
Note:
1.Views does not contain data in it. It fetches data from the database only depending on the condition ...
2.Views are part of data dictionary. They are a window to view the data in database
3.views can be used to give security to data. users can be allowed to view only basic data only
For More Info,go thru this Threads,

Unicode export:Table-splitting and package splitting

Hi SAP experts,
I know there are lot of forums related to this topic, but I have some new questions and hence posting a new thread.
We are in the process of doing unicode conversion in our landscape(CRM 7.0 system based on NW 7.01) and we are running on AIX 6.1 and DB2 9.5. The database size is around 1.5 TB and hence, we want to go in for optimization for export and import in order to reduce the downtime.As a part of the process, we have tried to do table-splitting and parallel export-import to reduce the downtime.
However, we are having some doubts whether this table-splitting has actually worked in our scenario,as the export has exeucted for nearly 28 hours.
The steps followed by us :
1.) Doing the export preparation using SAPINST
2.) Doing table splitting preparation, by creating a table input file having entries in the format <tablename>%<No.of splits>.Also, we have used the latest R3ta file and the dbdb6slib.o(belonging to version 7.20 even though our system is on 7.01) using SAPINST.
3.) Starting with the export using SAPINST.
some observations and questions:
1.) After completion of tablesplitting preparation, there were .WHR files that were generated for each of the tables in DATA directory of export location. However, how many .WHR files should be created and on what basis are they created?
2.) I will take an example of a table PRCD_CLUST(cluster table) in our environment, which we had split. We had 29 *.WHR files that were created for this particular table. The number of splits given for this table was 36 and the table size is around 72 GB.Also, we noticed that the first 28 .WHR files for this table, had lots of records but the last 29th .WHR file, had only 1 record. But we also noticed that, the packages/splits for the 1st 28 splits were created quite fast but the last one,29th one took a long time(serveral hours) to get completed.Also,lots of packages were generated(around 56) of size 1 GB each for this 29th split. Also, there was only one R3load which was running for this 29th split, and was generating packages one by one.
3.) Also,Our question here is that is there any thumb rule for deciding on the number of splits for a table.Also, during the export, are there any things that need to be specified, while giving the inputs when we use table splitting,in the screen?
4.) Also, what exactly is the difference between table-splitting and package-splitting? Are they both effective together?
If you have any questions and or need any clarifications and further inputs, please let me know.
It would be great, if we could get any insights on this whole procedure, as we know a lot of things are taken care by SAPINST itself in the background, but we just want to be certain that we have done the right thing and this is the way it should work.

Santosh Bhat

Hi,
First of all please ignore my very first response ... i have accidentally posted a response to some other thread...sorry for that
Now coming you your questions...
> 1.) Can package splitting and table-splitting be used together? If yes or no, what exactly is the procedure to be followed. As I observed that, the packages also have entries of the tables that we decided to split. So, does package splitting or table-splitting override the other, and only one of the two can be effective at a time?
Package splitting and table splitting works together, because both serve a different purpose
My way of doing is ...
When i do package split i choose packageLimit 1000 and also split out the tables (which i selected for table split) into seperate package (one package per table). I do it because that helps me to track those table.
Once the above is done i follow it up with the R3ta and wheresplitter for those tables.
Followed by manual migration monitor to do export/import , as mentioned in the previous reply above you need to ensure you sequenced you package properly ... large tables are exported first , use sections in the package list file , etc
> 2.) If you are well versed with table splitting procedure, could you describe maybe in brief the exact procedure?
Well i would say run R3ta (it will create multiple select queries) followed by wheresplitter (which will just split each of the select into multiple WHR files) ...
Best would go thought some document on table spliting and let me know if you have specific query. Dont miss the role of hints file.
> 3.) Also, I have mentioned about the version of R3ta and library file in my original post. Is this likely to be an issue?Also, is there a thumb rule to decide on the no.of splits for a table.
Rule is use executable of the kernel version supported by your system version. I am not well versed with 7.01 and 7.2 support ... to give you an example i should not use 700 R3ta on 640 system , although it works.
>1.) After completion of tablesplitting preparation, there were .WHR files that were generated for each of the tables in DATA directory of export location. However, how many .WHR files should be created and on what basis are they created?
If you ask for 10 split .... you will get 10 splits or in some case 11 also, the reason might be the field it is using to split the table (the where clause). But not 100% sure about it.
> 2) I will take an example of a table PRCD_CLUST(cluster table) in our environment, which we had split. We had 29 *.WHR files that were created for this particular table. The number of splits given for this table was 36 and the table size is around 72 GB.Also, we noticed that the first 28 .WHR files for this table, had lots of records but the last 29th .WHR file, had only 1 record. But we also noticed that, the packages/splits for the 1st 28 splits were created quite fast but the last one,29th one took a long time(serveral hours) to get completed.Also,lots of packages were generated(around 56) of size 1 GB each for this 29th plit. Also, there was only one R3load which was running for this 29th split, and was generating packages one by one.
Not sure why you got 29 split when you asked for 36, one reason might be the field (key) used for split didn't have more than 28 unique records. I dont know how is PRCD_CLUST split , you need to check the hints file for "key". One example can be suppose my table is split using company code, i have 10 company codes so even if i ask for 20 splits i will get only 10 splits (WHR's).
Yes the 29th file will always have less records, if you open the 29th WHR you will see that it has the "greater than clause". The 1st and the last WHR file has the "less than" and "greater than" clause , kind of a safety which allows you to prepare for the split even before you have downtime has started. This 2 WHR's ensures that no record gets missed, though you might have prepared your WHR files week before the actual migration.
> 3) Also,Our question here is that is there any thumb rule for deciding on the number of splits for a table.Also, during the export, are there any things that need to be specified, while giving the inputs when we use table splitting,in the screen?
Not aware any thumb rule. First iteration you might choose something like 10 for 50 GB , 20 for 100 GB. If any of the tables overshoots the window. They you can give a try by increase or decrease the number of splits for the table. For me couple of times the total export/import time have improved by reducing the splits of some tables (i suppose i was oversplitting those tables).

Using Case and Joins in update statement

Hi all,
I need to update one column in my table...but need to use case and joins...I wrote the query and it is not working
I am getting an error msg saying...the SQL command not ended properly...
I am not that good at SQL...Please help...
update t1 a
set a.name2=
(case
when b.msg2 in ('bingo') then '1'
when b.msg2 in ('andrew') then '2'
when b.msg2 in ('sam') then '3'
else '4'
end )
from t1 a left outer join t2 b
on a.name1 = b.msg1 ;
Waiting for help on this...!
Thanks in Advance... :)

Another approach is to update an inline view defining the join:
update
( select a.name2, b.msg2
from   t1 a
join   t2 b on b.msg1 = a.name1 ) q
set q.name2 =
    case
      when q.msg2 = 'bingo' then '1'
      when q.msg2 = 'andrew' then '2'
      when q.msg2 = 'sam' then '3'
      else '4'
    end;which could also be rewritten as
update
( select a.name2
       , case q.msg2
            when 'bingo' then '1'
            when 'andrew' then '2'
            when 'sam'    then '3'
            else '4'
         end as new_name
from   t1 a
join   t2 b on b.msg1 = a.name1 ) q
set name2 = new_name;The restriction is that the lookup (in this case, t2.msg1) has to be declared unique, via either a primary or unique key or unique index.
(You don't strictly need to give the view an alias, but I used 'q' in case you tried 'a' or 'b' and wondered why they weren't recognised outside the view.)

Select Distinct and join in ODI

Hi,
I have following task to perform: I am loading metadata into Planning dimension from Oracle database. I have two tables
1. "Sales"
Columns: Name, Number, Value
Sample Data:
Product 1, 10, 200
Product 2, 30, 100,
Product 1, 15, 500
2. P&R
Columns:
Name, Alias
Product 1, SampleSoda1
Product 2, SampleSoda2,
Resource 1, CanForSoda,
Resource 2, CO2
What I need to do is: I have to select name and alias from second table of all products that were sold.
So I need to select distinct Name from Table 1, naxt join it with Table 2 (so I have Name and Alias) and load it to planning.
I am a little confused how to do it.
Any help would be great!
Best regards,
Greg

Hi Greg,
What you can do is either :
- Create a yellow interface with your table Sales as source. Map the name column directly in the target. In the flow tab, click on your target and select "Distinct rows".
- Create a second interface, with your first interface as source. Select the "Use Temporary Interface as Derived Table (Sub-Select)" checkbox.
- Add your second datastore and join it. Or you can use a lookup table.
OR
- Create an interface with Sales and P&R as source (or set P&R as a lookup table).
- Go on the flow tab and select "Distinct rows".
If you've a lot a data in the first table, I would go for the first solution.
Hope it helps.

JeromeFr

Can we split and fetch the records in Database Adapter

Hi,
I designed a Database Adapter to fetch the records from oracle Database. Some time, the Database Adapter need to fetch around 5000, or 10,000 records in single shot. In that case my BPEL process is choking and getting error as
java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2882) at java.lang.AbstractStringBuilder.expandCapacity(AbstractStringBuilder.java:100)
Could someone help me to resolve this?
In Database Adapter can we split and fetch the records, if number of records more then 1000.
ex. First 100 rec as one set and next 100 as 2nd set like this.
Thank you.

You can send the records as batches useing the debatching feature of db adapter. Refer documentation for implementation details.

Macbook Pro 10.6.8 constantly drops my wi-fi network and joins Linksys which works but very slow

My Macbook Pro constantly drops my network and joins Linksys. It connects to the Internet but is painfully slow. Choosing my network again works for a while than goes back to Linksys. Any sugestions?

Try going to system preferences/network/advanced, airport tab, in the prefered networks pane highlight and drag your net work to the top of the list. See if it then chooses your network as prefered, hope this helps.
