JPA without Transactions?

Hi Folks,
Am I obliged to encompass my database write statements in a transaction? (Container managed or otherwise...)
em.merge(myObj);
em.flush();Our architecture is engineered so that transaction management is delegated to the database. JPA will (presumably) invoke an INSERT INTO or an UPDATE on a view which has some clever code, triggers etc. behind it to manage transactions.
A search of the forums returned these hits but my question is still unanswered.
* [Using JTA enabled connection in a JSP/servlet without transaction|http://forum.java.sun.com/thread.jspa?forumID=48&threadID=284423]
* [There must be transactions for a single update sql?|http://forum.java.sun.com/thread.jspa?forumID=48&threadID=458542]
The Spring site suggests that I must use transactions: [Can I use JPA without Transaction support?|http://forum.springframework.org/showthread.php?t=49322]
Is this really the case?
Thanks, Adam.

All customization tables without transaction

Hi all,
How can I find all the customization tables that cannot be accesses through specific transactions but only through the SPRO?
Thanks,
Roy

Hi Max,
Thanks this is a useful lead (gave you 6 points )
Could you please be more specific - I see entries where the OBJECTTYPE = T and that means that these are transactions that lead to the customizations tables, am I right?
And now the question is how I can filter only those without transactions
Thanks again for your assistance,
Roy

Query showing all customers with or without transactions

The content of the cube are all customers with transactions only. I want to create a report that will display all the customers with or without transactions. I tried to create a multiprovider combining the sales cube and customer master data. I created a query but it only displays the customes with transactions. Is there any other way wherein i can generate a report showing all customers with or without transactions?

hi,
the same problem happened, but no update whether it's solved, 'selection constant' should work
Multiproviders and filter on time
the link mentioned should be this

Goods receipt without transaction EIN (T030)

Hi,
some countries use transaction EIN.
At the goods receipt system creates an FI document.
If EIN is used In this document I can see the G/L purchasing account (debited) and the GR/IR clearing account (credited).
If I don't use transaction EIN (as in country Romania) system will not use the purchasing account.
So my question is:"When the purchasing account will be used" ?
Finance departement of my customer says that it will debited at the time of the goods issue....
I don't understand how to customize the system so that purchasing account will be debited at the time of goods issue
Could you help me ?
Best regards

Hi,
EIN will hit if the Purchase Account Management is active in your company code.......to check the same follow the below path.

Returning a ZERO on Slow-Moving Item without transaction

Hi all,
Via a multi-provider, we have implemented several slow-moving item in our reports, eg we return all the value of some dimensions whether we have transaction or not on these dimension values.
Now for dimension value for which we have no transaction it returns in Bex an empty result on the key figure instead of a zero, is there a way to force BW to put a zero on a slow-moving item without any transaction?
Thanks in advance for your assistance
David

Hallo
FI you go to the Query Designery --> Property Display than you can cusotmioze how to display the zero. You probably have the option Zero Values Display as Blank.
I hope this can help you

Logging without Transaction Support?

Can I use the the logging system to provide durability without using transactions. I want to have a simple key/value store that can survive system and application crashes and will be multithreaded. I will only be updating one key/value pair.
thanks

Hello,
Transactions are required for durability. In other words if you want your modifications
to persist in the event of application or system failure the application will need to
make use of transactions. This is discussed in the, "Getting Started with Berkeley
DB Transaction Processing" Guide at:
http://download.oracle.com/docs/cd/E17076_02/html/gsg_txn/C/introduction.html#txnintro
Thank you,

Transaction Variant for a standard report without transaction code

Hi,
I want to create a transaction variant for a executable report. The report has some subscreens 100, 110 etc. I want to hide the subscreen through transaction variant. So I have created a transaction code (Y*) for it and then tried creating transaction variant using SHD0 transaction. But the fields are not listed to choose invisible or other options. Please advice

The fields are listed when you leave each recorded screen. You have the flag "do not display the screen". It's strange you don't have anything, are you sure you started the recording? (you enter the transaction code, the transaction variant, you click the Create button and the screens are displayed and recorded)
Which transaction is it?
A little remark (about your last posts): forum rules ask people to give points, it's a way to say thank you. Otherwise, people won't help you anymore. It's not a black and white logic : don't give points only when your problem is solved. Give 2 or 5 points to thank people (or 0 if it's out of context). Thanks.

Report showing items without transaction data (materials without sales)

Hi,
I need to create a report (in BW for retail), listing all the articles that has not been sold for a given month and store (plant). My thought was to create a report, setting a condition listing quantity = 0 and set Access type for result values to Master data. But this is not working.
Having tried the standard SAP slow seller query on the material movements qube (0IC_C03), I did not see this giving me materials with no movement.
Anybody have any tips how to solve a query where you need to list master data that does not have any transactional data in the cube?
My only thought is to create a new cube, and fill by looping on my material master and looking to the transactional data and if there is not hit, the material has not been sold that month, but I'm hoping for a smoother solution.
Any help is much appreciated.
Regards,
Øystein

Hi,
thanks for you reply.
I have tried the query with show all master data and condition quantity = 0, and this list a huge list of articles, (to me it seems like the whole material master). Luckily it's not a huge retailer, the material master is aprox 50k records. But the output did not seem to be correct. And it was slow. And again, no store will be keeping the whole material master for sale, so this will list everything, not just the ones relevant to the store.
My second option will require more work, by updating a "no sale" cube/dso and loop on all master data, but this will be done once a month, and then the work is done at evening/nights, and the report should be fast. It's not to much work to create the routine, but running it I assume will be time consuming.
Regards,
Øystein
