Storing Data in structure?

Hi,
i want to store some data in structure, but i don't no in which way i should do this.
for example i send some data in adpu command.
the first 4 bytes identify an id the next 4 bytes identify a subid and the next 4 bytes identify an value. but there is a variable amount of subids and values i send.
the structure should look something like this.
id
- subid1
- value1
-subid2
- value2
-subidn
- valuen
i hope you can understand what i mean.
has someyone an idea how can this be done? i'm thankful for any suggestion.
it's a little bit urgent because it's for my final year project.
thanks
markus

Markus,
There are standards for doing this sort of thing. You should look into the following topics:
BER-TLV (Basic Encoding Rules - Tag Length Value)
Simple-TLV
Basically, a BER-TLV may contain multiple simple TLV(s). Define tags for your data objects, then go ahead and construct messages.
So:
<ber-tag><ber-len>[<simple-tag><simple-len><simple-val>...]
Good luck with that final project, I hope you pass.

Storing data in structured storage

I see everywhere that storing data in stuctured storage way is the better thing to do if we want to make fast search.
But how can I do it.
I only see that the default storage is clob for xmltype and we also can say "stored as clob" but how do it for store it in structured storage.
Thank you.

You need to register an XML Schema that defines your data. You then define the type of data your XML columns will contain using XMLSCHEMA and ELEMENT clauses..
See the XML DB demo for more info

How to retreive data from structure MDEZ in T.code CO09

As per our requirement 2 new columns are needed in a customize report .i.e
- u201Cinc. lot dateu201D
- u201Cavailable inc. lotu201D
u201Cinc. lot dateu201D:to get the values for inc.lot.date
From second screen of CO09(program: SAPLATP4 and screen number: 400) pick first date where MRP element is u201CPOitemu201D, u201CShpgNtu201D or u201CPrdOrdu201D.
u201Cavailable inc. lotu201D: to get the values for available inc.lot
Pick u201CCum. ATP QTyu201D from the same row.
These data are stored in structure MDEZ. Actually I want dat00 and MNG04 based on field DELB0. If DELB0 filed is POitem or Prdord or ShpgNt then only I should retrieve the dat00 and MNG04. IF there are more than one POitem in MRP element then we should pick the first POitems' mrp date and *** ATP qty .Can you please help me out how to get these data from the structure MDEZ.
input parameters to get the values are material number and plant.

Hi,
First of all data is never stored in structure so there is no way you can retrive data from structure.
you are looking into the screen field and it is not mandatory that it will always point to a table.
Now the qestion remains how to get the data ? you need to find database table for that field there are many ways like SE84 or SE11 where used etc.
Try to find the table if you still have the problem feel free to get back.

DATA from structure

hi firends,
i need to retreive data from table and structure is it possible
eg-- AAA is table having atr no
      BBB is strucrure in run time its having some data related to AAA table atrno
i want a select query for this plz some one provide me with example code
but i know structure will not store value.my requirement is for IDOC so structure carries data so ineed to track that
pointe will be rewarded
thanks in advance
raj

Hi Raj ,
basically addition or deletion of segments the data holds in the data record structure.
all the data pertaining to the idoc is stored and processed
in the structures
EDIDC--> Control Records.
EDIDD --> Data srecords.
goto se37 and enter the FM name
f7
u 'll see
TABLES
*"      IDOC_CONTRL STRUCTURE EDIDC
*"      IDOC_DATA     STRUCTURE EDIDD
now if i want to know the data this is is structure EDIDD now in itab
IDOC_DATA.
BREAK-POINT.
LOOP AT IDOC_DATA.
ITAB-F1 = ID0C_DATA-F1.
ITAB-F2 = ID0C_DATA-F2.
ITAB-F3 = ID0C_DATA-F3.
APPEND ITAB.
CLEAR ITAB.
ENDLOOP.
this way u can fetch the data .

SAP paging overflow when storing data in the ABAP/4 memory.

I am trying to create a data source in BI7.0 in the Datawarehousing Workbench. But along the process when i need to select a view i get an error detailed in the following error file extract: Please go through and assist.
untime Errors MEMORY_NO_MORE_PAGING
Date and Time 06.06.2009 14:21:35
Short text
SAP paging overflow when storing data in the ABAP/4 memory.
What happened?
The current program requested storage space from the SAP paging area,
but this request could not be fulfilled.
of this area in the SAP system profile.
What can you do?
Note which actions and input led to the error.
For further help in handling the problem, contact your SAP administrator
You can use the ABAP dump analysis transaction ST22 to view and manage
termination messages, in particular for long term reference.
Error analysis
The ABAP/4 runtime system and the ABAP/4 compiler use a common
interface to store different types of data in different parts of
the SAP paging area. This data includes the
ABAP/4 memory (EXPORT TO MEMORY), the SUBMIT REPORT parameters,
CALL DIALOG and CALL TRANSACTION USING, as well as internally defined
macros (specified with DEFINE).
To store further data in the SAP paging area, you attempted to
allocate a new SAP paging block, but no more blocks were
available.
When the SAP paging overflow occurred, the ABAP/4 memory contained
entries for 20 of different IDs.
Please note:
To facilitate error handling, the ABAP/4 memory was
deleted.
How to correct the error
The amount of storage space (in bytes) filled at termination time was:
Roll area...................... 8176
Extended memory (EM)........... 13587912
Assigned memory (HEAP)......... 0
Short area..................... " "
Paging area.................... 40960
Maximum address space.......... " "
By calling Transaction SM04 and choosing 'Goto' -> 'Block list',
you can display an overview of the current roll and paging memory
levels resulting from active users and their transactions. Try to
decide from this whether another program requires a lot of memory
space (perhaps too much).
The system log contains more detailed information about the
termination. Check for any unwanted recursion.
Determine whether the error also occurs with small volumes of
data. Check the profile (parameter "rdisp/PG_MAXFS", see
Installation Guidelines).
Is the disk or the file system that contains the paging file
full to the extent that it cannot be increased, although it has
not yet reached the size defined in the profile? Is the
operating system configured to accommodate files of such a
size?
The ABAP processor stores different types of data in the SAP
paging area. These include:
(1) Data clusters (EXPORT ... TO MEMORY ...)
(2) Parameters for calling programs (SUBMIT REPORT ...),
Dialog modules (CALL DIALOG ...) and transactions
(CALL TRANSACTION USING ...)
(3) Internally defined program macros (DEFINE ...)
Accordingly, you should check the relevant statements in a program
that results in an overflow of the SAP paging area.
It is critical when many internal tables, possibly with
different IDs, are written to memory (EXPORT).
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"MEMORY_NO_MORE_PAGING" " "
"SAPLWDTM" or "LWDTMU20"
"TABC_ACTIVATE_AND_UPDATE"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.
Restrict the time interval to 10 minutes before and five minutes
after the short dump. Then choose "System->List->Save->Local File
(Unconverted)".
3. If the problem occurs in a problem of your own or a modified SAP
program: The source code of the program
In the editor, choose "Utilities->More
Utilities->Upload/Download->Download".
4. Details about the conditions under which the error occurred or which
actions and input led to the error.

Hi Huggins,
Maintenance of the Paging File is owned by your basis team.
They should increase this in order for your transaction to process successfully.
Just for your reference, in case the OS used is windows server 2003, paging file value can be checked through;
Right click in the My Computer>properties.
Then go to Advance tab;
Then there should be a performance section, click the settings
Then Advance tab again. The paging file can be seen from there.
(and can be adjusted from there also)
The value of the paging file in general will be dependent with the available RAM from the hardware.
Hope this helps. Thanks a lot.

Why files in Lightroom mobile and files in the creative cloud not the same? idea- one place(stored date) for all application ??????

Why files in Lightroom mobile and files in the creative cloud not the same? idea- one place(stored date) for all application ??????

Lightroom Mobile is not a cloud storage service. You shouldn't treat it as a way of backing up your files. You are merely storing Smart Previews of your files in the cloud space, high-quality JPEGs of your files regardless of their original format on your desktop. The point is that they are there so you can continue editing them in a Lightroom-like environment even while away from your desktop/laptop computer. The files in Lightroom Mobile can only be used in Lightroom Mobile.
This is very different from what is offered by the Creative Cloud storage, which can be used to synchronize your files between any device (that can support the individual files).
The vast difference in how each service works and its intended use is why they are separate.

LBBIL_INVOICE. Billing Data: Transfer Structure to Smart Forms

Hi...
Can u please help me out in my query regading how the data passes to
LBBIL_INVOICE. Billing Data: Transfer Structure to Smart Forms.
I have an smartform which runs through VF01/VF02/ VF03 while pressing the print preview button.
But if i try to run it directly from driver program, no data wil be displayed. Now i have the requirement to detach from VF03.. and make it to run directly from my driver program.
what shall i have to do to achieve this. Should i have to take all the internal tables saparately or else can i use LBBIL_invoice structure itself.
If i can use that structure itself, how to make the data flow into it. Pls help me.
In my codeing these includes were there. is there anything related , is the data passes because of these includes
INCLUDE rlb_invoice_data_declare.
definition of forms
INCLUDE rlb_invoice_form01.
INCLUDE rlb_print_forms.
Pls clarify my dobut...
Thanks in advance,
Hema

1. These are normal structure
2. you can use anywhere but they designed for forms currently.
3. Yes ,it works like it will look at NAST Table -> nast table will connect the TNAPR Table -> tnapr will have smart form print program.
so smart form program calls smartform and it will show output
4. you can create your own structure and use them into anywhere like report program or forms..
5. you can see example simple form name SF_EXAMPLE_01 ,program name is SF_EXAMPLE_01 ,you can design your own form and print program.
Thanks

What is difference between data base structure and stucure in program

what is difference between data base structure and stucure declared in program level . can explain cleary if knows

Hi,
Data base structure is global decalaration you can reffer this structure in any of your developments, when ever you cahange this structure the changes automatically will get updated in all the programs.
coming to structures in program it is local to your program only, if you want to change the structure again you have to open the program and do the necessary changes.
Reward if useful.
Thanks,

If i associate my apple id with another email will i lose my icloud data or i will still be able to access all my stored data with the new linked to my apple id email address?

hi there
if i associate my apple id with another email will i lose my icloud data or i will still be able to access all my stored data with the new linked to my apple id email address?
i mean i am not signing up for a new account, just changing my old id primary email which is my apple id login into account.
in other words, www.icloud.com will recognize that it is still me if i login on the site? will i be able to see there all my stored information?
and if i change my password, does it automatically changes the @icloud.com password which should be the same as my apple id pass?
thanks

After opening the email it shoud of had you enter the Apple ID and password. Using certian web browser's can cause errors. You can adjust securty settings (big pain) or you use another browser. Using Firefox or Safari should do the trick.
Let me know if using Firefox or Safari resolved it.

How to find all the Master data extract structures and Extractors

I intend to create Master data dimensions closely similar to SAP BI in a 3rd party system. I would like to use SAP's standard extractors for populating the master data structures in SAP BI and then use a proprietary technology to create similar structures in a 3rd party database.
Question: How to get a complete list of all Master data extract structures and corresponding extractors?
Example: In ECC if I do SE80 and give 'Package' and 'MDX' and then press the 'display' spectacles, I get a list of structures and views under "dictionary objects" covering Material, Customer, Vendor, Plant Texts and attributes.
How do I get the remainder of the Master data extract structures viz. Purchase Info Records, Address, Org Unit etc?
Regards
Sasanka

Hi,
try the table ROOSOURCE and search the data source with string in astrick attr for master data and for text with text
This will give you the list of all the master data source in the system and it contains a column which tells about the extract structure and function module used by each.
Thanks

Processing a data mining structure throws an error

Processing a data mining structure throws an exception stating the following:
"Errors in the OLAP storage engine: An error occurred while the 'IDK' attribute of the 'Test IDK' dimension from the 'Project1' database was being processed."
"Errors in the OLAP storage engine: The attribute key was converted to an unknown member because the attribute key was not found. Attribute IDK of Dimension: Test IDK from Database: project1, Record:17072643"
I am using a DB view as a DSV. It does not have a unique primary key. Since DB view is getting multiple results per IDK, the IDK repeats for multiple rows. The same IDK is defined as Key column for the mining model. Not sure if that is the
issue. Please help!
Thanks
Shallu

Hi Shallu,
According to your description, you use a database view in the data source view that do not have a primary key, so you get the error
Errors in the OLAP storage engine: The attribute key was converted to an unknown member because the attribute key was not found. Attribute IDK of Dimension: Test IDK from Database: project1, Record:1707264
when processing the project, right?
In this case, please refer to the links below which describe the similar issue.

Write / store xml data in Xe and retrieve stored data using pl/sql

Hi to all,
i'm searching a tutorial on:
A - how to write / store xml data in Xe and retrieve stored data using pl/sql
I don't want to use other technologies, because i use htmldb and my best practice is with pl/sql.
I was reading an ebook (quite old maybe) however it's about oracle 9 and it's talking about xmltype:
1 - I don't understand if this is a user type (clob/varchar) or it's integrated in Oracle 9 however i will read it (it's chapter 3 titled Using Oracle xmldb).
Please dont'reply here: i would be glad if someone can suggest me a good tutorial / pdf to achieve task A in Oracle XE.
Thanx

Thank you very much Carl,
However my fault is that i've not tried to create the table via sql plus.
Infact i was wrong thinking that oracle sql developer allows me to create an xmltype column via the create table tool.
however with a ddl script like the following the table was created successfully.
create table example1
keyvalue varchar2(10) primary key,
xmlcolumn xmltype
Thank you very much for your link.
