LSMW: What are Fixed Values and Translations for?

Hi,
I'm working with LSMW and I don't know what are Fixed Values and Translations for? They are on the "Maintain Fixed Values, Translations, User-Defined Routines" step.
Thanks in advance,
Gerard

this is the step,we can process the reusable rules of a project.
<b>Fixed value:</b> Here you can specify length, type, flag for lowercase/uppercase and value in addition to the description.
this is nothing but CONSTANTS in your report programs.
<b>Translation:</b> Here you can enter information on the source field and the target field.
for example, your input file language value will be 2 characters and we need to send only 1 for LANG in SAP.
so here we have to do the translation of 2chars to 1 char.
so, we will give these set of values in this step.

Fixed and variable sizes

hi,
i have a dought. What exactly the fixed and variable sizes represent in oracle.
regards,
kishore.

hi kishore, seems you are using forums very well these days... :-)
Part of the SGA contains general information about the state of the database and the instance, which the background processes need to access; this is called the fixed SGA. No user data is stored here. The SGA also includes information communicated between processes, such as locking information.

Hi
Field Symbols
Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned to it after it has been declared in the program.
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to each field symbol before you can address the latter in programs.
Field symbols are similar to dereferenced pointers in C (that is, pointers to which the content operator * is applied). However, the only real equivalent of pointers in ABAP, that is, variables that contain a memory address (reference) and that can be used without the contents operator, are reference variables in ABAP Objects.
All operations programmed with field symbols are applied to the field assigned to it. For example, a MOVE statement between two field symbols moves the contents of the field assigned to the first field symbol to the field assigned to the second field symbol. The field symbols themselves point to the same fields after the MOVE statement as they did before.
You can create field symbols either without or with type specifications. If you do not specify a type, the field symbol inherits all of the technical attributes of the field assigned to it. If you do specify a type, the system checks the compatibility of the field symbol and the field you are assigning to it during the ASSIGN statement.
Field symbols provide greater flexibility when you address data objects:
If you want to process sections of fields, you can specify the offset and length of the field dynamically.
You can assign one field symbol to another, which allows you to address parts of fields.
Assignments to field symbols may extend beyond field boundaries. This allows you to address regular sequences of fields in memory efficiently.
You can also force a field symbol to take different technical attributes from those of the field assigned to it.
The flexibility of field symbols provides elegant solutions to certain problems. On the other hand, it does mean that errors can easily occur. Since fields are not assigned to field symbols until runtime, the effectiveness of syntax and security checks is very limited for operations involving field symbols. This can lead to runtime errors or incorrect data assignments.
While runtime errors indicate an obvious problem, incorrect data assignments are dangerous because they can be very difficult to detect. For this reason, you should only use field symbols if you cannot achieve the same result using other ABAP statements.
For example, you may want to process part of a string where the offset and length depend on the contents of the field. You could use field symbols in this case. However, since the MOVE statement also supports variable offset and length specifications, you should use it instead. The MOVE statement (with your own auxiliary variables if required) is much safer than using field symbols, since it cannot address memory beyond the boundary of a field. However, field symbols may improve performance in some cases.

Syntax Diagram
FIELD-SYMBOLS
Basic form
FIELD-SYMBOLS <fs>.
Extras:
1. ... TYPE type
2. ... TYPE REF TO cif
3. ... TYPE REF TO DATA
4. ... TYPE LINE OF type
5. ... LIKE s
6. ... LIKE LINE OF s
7. ... TYPE tabkind
8. ... STRUCTURE s DEFAULT wa
The syntax check performed in an ABAP Objects context is stricter than in other ABAP areas. See Cannot Use Untyped Field Symbols ad Cannot Use Field Symbols as Components of Classes.
Effect
This statement declares a symbolic field called <fs>. At runtime, you can assign a concrete field to the field symbol using ASSIGN. All operations performed with the field symbol then directly affect the field assigned to it.
You can only use one of the additions.
Example
Output aircraft type from the table SFLIGHT using a field symbol:
FIELD-SYMBOLS <PT> TYPE ANY.
DATA SFLIGHT_WA TYPE SFLIGHT.
ASSIGN SFLIGHT_WA-PLANETYPE TO <PT>.
WRITE <PT>.
Addition 1
... TYPE type
Addition 2
... TYPE REF TO cif
Addition 3
... TYPE REF TO DATA
Addition 4
... TYPE LINE OF type
Addition 5
... LIKE s
Addition 6
... LIKE LINE OF s
Addition 7
... TYPE tabkind
Effect
You can define the type of the field symbol using additions 2 to 7 (just as you can for FORM parameters (compare Defining the Type of Subroutine Parameters). When you use the ASSIGN statement, the system carries out the same type checks as for USING parameters of FORMs.
This addition is not allowed in an ABAP Objects context. See Cannot Use Obsolete Casting for FIELD SYMBOLS.
In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. See Defining Types Using STRUCTURE.
Effect
Assigns any (internal) field string or structure to the field symbol from the ABAP Dictionary (s). All fields of the structure can be addressed by name: <fs>-fieldname. The structured field symbol points initially to the work area wa specified after DEFAULT.
The work area wa must be at least as long as the structure s. If s contains fields of the type I or F, wa should have the structure s or at least begin in that way, since otherwise alignment problems may occur.
Example
Address components of the flight bookings table SBOOK using a field symbol:
DATA SBOOK_WA LIKE SBOOK.
FIELD-SYMBOLS <SB> STRUCTURE SBOOK
DEFAULT SBOOK_WA.
WRITE: <SB>-BOOKID, <SB>-FLDATE.
Field Groups
Field groups use a mechanism called extract to store and process data. You define a header and then line structure and the fields that you would like those to have and process them fairly similarly to a table; unless you are dealing with millions of records.
Since internal tables have fixed line structures, they are not suited to handle data sets with varying structures.
An extract is a sequential dataset in the memory area of the program. You can only address the entries in the dataset within a special loop. The index or key access permitted with internal tables is not allowed. You may only create one extract in any ABAP program. The size of an extract dataset is, in principle, unlimited. Extracts larger than 500KB are stored in operating system files. The practical size of an extract is up to 2GB, as long as there is enough space in the file-system.
Reward points if this explains well

Resize Video, both the file size and actual size

Hi All,
I am very new to Adobe Premiere (CS3). I have had it for a while but not needed to use until now. A client of mine has sent me a video that he wants on his website. But it’s 150M and 1280 * 720. Can anyone help me out with how I can resize both the file size and actual size to say 800 * 450 so it can stream it via the net?
Like I said very new to this,
Cheers,
Mike.

The first thing you need to do is determine just what KIND of file you were sent, so you may start a project that matches the file

What are the advantages and disadvantages for the larger blocksize and for the smaller blocksize?

Smaller blocksize
Advantages
GoodHas relatively large space overhead due to metadata
(that is, block header).
Not recommended for large rows. There might only
be a few rows stored for each block, or worse, row
chaining if a single row does not fit into a block, for small rows with lots of random
access.
Reduces block contention.
Disadvantages
Has relatively large space overhead due to metadata
(that is, block header).
Not recommended for large rows. There might only
be a few rows stored for each block, or worse, row
chaining if a single row does not fit into a block.
Larger blocksize
Advantages
Has lower overhead, so there is more
room to store data.
Permits reading a number of rows into
the buffer cache with a single I/O
(depending on row size and block size).
Good for sequential access or very large
rows (such as LOB data).
Disadvantages
Wastes space in the buffer cache, if you are doing
random access to small rows and have a large block
size. For example, with an 8 KB block size and 50
byte row size, you waste 7,950 bytes in the buffer
cache when doing random access.
Not good for index blocks used in an OLTP
environment, because they increase block contention
on the index leaf blocks.

Do you have a performance problem yet ??
Is the problem a global problem in the whole database, or are there just some queries that are slow ??
What db version are you using ??
What other applications are using this server ??
How many users are using this database ??
Tuning is very much dependent on the application/situation and database type.

What are the advanteges and disadvanteges of using pl/sql over hibernate

i knwo that pl/sql are well structure and provide a lot of functionalities with oracle databse , but my question is the hibernate might give some advnateges of scalability over pl/sql.
so what are the advanteges and disadvanteges of using pl/sql over hibernate?
and does oracle recommend using hibernate for connecting JSP with oracle 11i , or it is better to connect the JSP pages with oracle databse using pl/sql ?

but if i search for the diferencess then there are a lot of opinions about this ..., specially when they say that with hibernate you can integrate with any DB , and it provides object printed architecture, etc.All databases are not equal. This is a basic and fundamental fact. SQL-Server is not Oracle. Oracle is not SQL-Server. As it is the case with Sybase, Ingres, DB2 and other database products. They are all different. And there are some very core differences between them.
So how would a product like Hibernate treat these database products with their differences? By using the lowest common denominator. Which means your expensive database product is dumbed down - and even MS Access will likely have better and more features.
You also need to decide what is the "permanent" part in your architecture. What is going to the core? What is the expensive part? The app server (with Hibernate)? Or the database server?
What are you likely to change next year? The app server server? Or the database server?
In the vast majority of cases, the core is the database server. That is your biggest expense and investment. As it should be - as it holds that which is most precious to business, data. You want to ensure the integrity of that data. The accuracy of that data. Make sure that it can be easily backed up and recovered. Is flexible to use. Etc. Etc.
The database server is the core - and that is where you need to realise your return on investment. By using the database server to its full extent.
Hibernate does not do that. And in that respect, it is junk.
Why does it not do that? Because many Java developers are totally and fully clueless about what database servers are and how to use them. And want to use them as little plug-in black boxes - bit buckets that are only there to provide a data persistence layer. Instead of using the database server to its full extent, they instead use Hibernate, and try to do their own "+database thing+" in the app layer - and do it poorly and with utter lack of any scalability. (and no, only ignorant Java heads think that scalability means throwing more money and h/w at it)
My largest database processes billions of rows per day, every day, 356 days a year (between 350 to 450 million new inserts into a single table per day). And have been for several years now. It does so using PL/SQL. Using Oracle to its full extent. Then there are Java heads that cannot even design and code an app that effectively process 1% of this volume... and grasp at straws like Hibernate and other Java cr@p to "fix" this - when the actual problem is their total lack of ignorance in how to use and scale the database server.
Hibernate is trash - and a symptom of Java developers's ignorance of database technology.

Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol.

You must assign a field to each field symbol before you can address the latter in programs.
Field Groups:
A field group is a user-defined grouping of characteristics and basic key figures from the EC-EIS or EC-BP field catalog.
Use
The field catalog contains the fields that are used in the aspects. As the number of fields grows, the field catalog becomes very large and unclear. To simplify maintenance of the aspects, you can group fields in a field group. You can group the fields as you wish, for example, by subject area or responsibility area. A field may be included in several field groups.
When maintaining the data structure of an aspect, you can select the field group that contains the relevant characteristics and basic key figures. This way you limit the number of fields offered.
A field group combines several existing fields together under one name
like
FIELD-GROUPS: fg.
then you can use one insert statement to insert values in fields of field-group.
INSERT f1 f2 ... INTO fg.
Field symbols
If u have experience with 'C', then understand this to be similar to a pointer.
It is used to reference another variable dynamically. So this field symbol will simply point to some other variable. and this pointer can be changed at runtime.

what are the advantages and disadvantages of suppressed and unsuppressed content in indesign layer option?

I occasionally use layers set to suppress output for holding text that differs from the text in the visible part of a document that I need for variables or TOC entries sometimes, or for notes or guides I want in the file but I don't want printed. You might also want to suppress a layer with some sort of overlay, like the die-lines for a die-cut piece, when you export a PDF for screen viewing.
I'm sure you can come up with other reasons for having content on a page in the layout, but not in the final output.

I customize my paper size and print size and am then viewing a photo on my screen. I print it out and it chops off about 5% of all edges of my original photo on the screen. Why does it do that? It is driving me crazy. I use an Epson Photo 2200 printer.

What print and paper sizes are you using? Are you trying to print a borderless print? Does your printer support borderless for that particular size? Are you printing to the custom stock size or to a larger stock size?

Getting file header size and image size

Hi all,
Now that the AVI file type won't work for me, I have to do some of that functionality myself.
I can use the function to Get File Size, and the size is returned in bytes, so far so good.
I figured I could calculate the image size by taking the resolution, multiply X and Y, that gives me the number of pixels.
Then multiply pixels by bit depth, to get the number of bits, divide by 8 for the number of bytes.
Since bit depth is 8, the number of bytes will be exact (and the same as the number of pixels).
When I did the math, and divided by the file size, it didn't come to a round number, and was a larger number than the number of images I could display.
I figured there is probably additional information stored with each image, but I don't know how to adjust for that.
There may be byte clustering happening, making each image larger than the actual byte count would indicate.
And, there is probably file header info, but not sure where to get that.
I looked through the IMAQ functions, and didn't see one about getting the image size (I did see the one that returns resolution, but I have that data already).
Any suggestions on how I can calculate how many images are in my binary file?
And, how to get the byte sizes I need to be able to set the file pointer correctly to get an image out of the middle of the file?
Thank you for any suggestions,
Jeff

If I understand correctly You have binary file with multiple images inside and You want to extract that images?
Depending on image type You can search by tags where image begins and ends: http://www.impulseadventure.com/photo/jpeg-decoder.html and extract.
