How to get generated sequence number from JPA/TopLink

Hi there,
I am using JDev 10.1.3.3 with JPA + POJO + TopLink.
In the entity (POJO), I declared a sequence generated for a number field.
@Id
@GeneratedValue(strategy=SEQUENCE, generator="GEN_CUSTOMER_ID_SEQ")
@SequenceGenerator(name="GEN_CUSTOMER_ID_SEQ", sequenceName="CUSTOMER_ID_SEQ", allocationSize=1)
@Column(name="CUSTOMER_ID", nullable = false, precision = 12 )
private Long customerId;
In my program, I don't need to set the Id field because it is set automatically.
However, I want to get the generated sequence using code. Is there a way?
Thanks,
Jim
P.S. I cannot use getCustomerId because the value has not been set yet.

If you call persist on the new Entity, or flush() the id will be assigned, and you can get it.
There is also an API on the TopLink / EclipseLink Session getNextSequenceNumberValue(), that you can use to get a sequence value.

How to get Accounting document number from billing document number

Hi,
How to get Accounting document number from billing document number i.e. from VBAK- VBELN.
Cheta Pant

Hi,
VBAK is the Sale Order header table, Billing document table is VBRK.
Sales tables (VBAK,VBAP,VBRP,VBRK) do not store accounting document numbers.
You do other way around. Just go to SE16 and enter the Billing document number in field Billing document VBELN in BSEG or BSID or BSAD table and execute, you will find the accounting document number.
If you just want collect this information once then you can use table BSEG, but if you think to develope a report then use table BSID and BSAD.

Hello,
E-mail data extraction is done by method EMAIL_DATA_EXTRACT from class /SAPSRM/CL_OFFLINEAPP_INBOUND.
With the exporting parameter EV_WIID, call function BBP_PDH_WFL_OBJECT_WI_GET: you will get the Shopping Cart number.
To have an idea of the whole mail data extraction process, check report /SAPSRM/OFFLINEAPPROVALGET

How to get Cost Center number from a Customer

Hi Sap Experts,
I have a customer number from xd03. But I would like to know which is the cost center used by this customer, how can I find that?
Because I'm getting an warning message when using FB08, it points to the Tax Jurisdiction issue. I believe at some point, it's checking the Jurisdiction field of the cost center.
Regards,
CHL

Hi,
Thank you for the reply.
The thing is, when I run FB08 for a specific document, i'm getting this warning Msg: Account assignment object has jurisdiction code XX, line iten XX AAAAAA.
I checked already the configurations for jurisdiction code in customer master data and the path "define tax jurisdiction code" with spro.
I noticed something, during the debug at some point its reading the cost center's jurisdiction number, and will compare it with customer's master data jurisdiction.
But if there's no cost center it will process fine.
It's in the program SAPLKAIP, form CostCenter_Check. Not sure if it's SAP standard code.
Cheers.

How to get a decimal number from three single byte numbers

i'am in a difficult situation. I have motor which provides me the number of steps moved as three numbers of length one byte.I 'am attaching the program with this message. Here the commands from index 2-4 outputs will provide the number of steps moved. But these are numbers with a single byte length(<256). So how can I get the corresponding decimal number from these three single byte length numbers. please reply

Without knowing what motor you are using, I'm guessing that you probably need to use the Join Numbers to combine the bytes into a U32. The other option is to use the Type Cast function.

How to get the BP number from OBJECT ID or ID rel.Object taken from HRP1001

Hi Gurus
I am trying to find the BP number from the OBJECT ID or ID rel.Object which i got from the table HRP1001 in CRM but i am not able to find the link straightaway to get that details
Kindly help me to find out the table where i can simply put the OBJECT ID or ID rel.Object to get the BP number for ROLE EMPLOYEE
Thanks a lot
Regards
Soni

Hi Soni,
I found this in a different thread:
first you get the all connected partners to a position by selecting SOBID from hrp1001 (with OTYPE / OBJID of position, RELAT = 008, SCLAS = CP).
With this SOBID go again to HRP1001 and fill the SOBID into OBJID (with OTYPE = CP, SCLAS = BP) and the SOBID of the result is the connected partner number.
You can also use FM 'CRM_CENTRALPERSON_GET' instead of the last SELECT-Statement. Here IV_PERSON_ID = SOBID (of first select). You get the partner guid and can get data of the partner from but000.
In this thread:
Help needed...Infotype HRP1001--Getting details OF Position Users...
Hope it helps.

Wim

How to get sd major number from my driver

Hi,
I have a specific question. I have a driver (mydriver) that acts like a filter driver.
When it receives IO from the file system through strategy() routine, it wants
to replace its b_edev with that of sd device instance. mydriver creates minor
nodes exactly as sd driver. All I need is to know what is the major number
of sd driver. How do I do this programmatically through mydriver?
Your help is greatly appreciated.
Thanks,
sudhakar

Hi,
I am trying to develop a "filter driver" at the file system level for Solaris to get the statistics of some of I/O calls send to a SCSI device. It exists between the VFS and the file-system-dependent layer. Does anyone has experience in developing such a "pseudo file system module". Please share your experience and suggestions.
Initially I was thinking to develop this by getting the "st" major number. That is the reason it is been posted as a reply to this query.
Thanks in advance
