Difference between fields MENGE and MNGLG

Hi All,
Can any one explain me the difference between fields MENGE and MNGLG ( both are Component Qty).
I need to know this we are developing a report based on
CS12, CS13…and which one I need to consider.
Thanks for the help

Hi,
MNGLG field gives the calculated component quantity based on your input required quantity EMENG. The value of which will match with the production order. ( no rounding off )
EMENG is the quantity of the parent product that you want to produce and then the function module will return you with the quantities of each of the components required to make this quantity of the parent product. The fields MNGLG, MNGKO will give you the required component quantity in base unit of measure and component unit of measure(as per the BOM).

Difference between Field symbols and field group

Hi experts,
Can you please advice me what is the difference between field symbols and field groups.
Thanks in advance,
Logu.

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 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.
FIELD-SYMBOLS <FS>.
DATA FIELD VALUE 'X'.
ASSIGN FIELD TO <FS>.
WRITE <FS>.

The difference between FIELD-SYMBOL and normal DATA TYPE

Dear experts,
Please see the example below, both are output the same result.
DATA: EXTERNAL_RECORD(4000),
      POSITION TYPE I,
      LENGTH TYPE N,
      ENTRY TYPE STRING.
EXTERNAL_RECORD = '0005Smith0007Edwards0005Young'.
DO.
LENGTH = EXTERNAL_RECORD+POSITION(4).
IF LENGTH = 0.
    EXIT.
ENDIF.
ADD 4 TO POSITION.
MOVE EXTERNAL_RECORD+POSITION(LENGTH) TO ENTRY.
WRITE ENTRY.
ADD LENGTH TO POSITION.
IF POSITION >= 4000.
    EXIT.
ENDIF.
ENDDO.
--OR It can be written as--
DATA: EXTERNAL_RECORD(4000),
      POSITION TYPE I,
      LENGTH TYPE N.
FIELD-SYMBOLS <ENTRY>.
EXTERNAL_RECORD = '0005Smith0007Edwards0005Young'.
DO.
LENGTH = EXTERNAL_RECORD+POSITION(4).
IF LENGTH = 0.
    EXIT.
ENDIF.
ADD 4 TO POSITION.
ASSIGN EXTERNAL_RECORD+POSITION(LENGTH) TO <ENTRY>.
WRITE <ENTRY>.
ADD LENGTH TO POSITION.
IF POSITION >= 4000.
    EXIT.
ENDIF.
ENDDO.
Is there any special circumstances we need to use FIELD-SYMBOL?
Why is FIELD-SYMBOL is introduce in the first place?
Kindly advice with example.
Thanks in advance for those who can help me on this.

HI,
You can use field symbols to make the program more dynamic. In this example the name of a table control is substituted by a field symbol. Thus you cal call the form with any internal table, using the name of the table control as a parameter.
Example
form insert_row
using p_tc_name.
field-symbols <tc> type cxtab_control. "Table control
assign (p_tc_name) to <tc>.
insert 100 lines in table control
<tc>-lines = 100.
Field symbols allow you to:
**     Assign an alias to a data object(for example, a shortened
        name for data objects structured through several hierarchies
        - <fs>-f instead of rec1-rec2-rec3-f)
**     Set the offset and length for a string variably at runtime
**     Set a pointer to a data object that you determine at runtime (dynamic ASSIGN)
**     Adopt or change the type of a field dynamically at runtime
**     Access components of a structure
**     (from Release 4.5A) Point to lines of an internal table
        (process internal tables without a separate work area)
Field symbols in ABAP are similar to pointers in other programming
languages. However, pointers (as used in PASCAL or C) differ from ABAP
field symbols in their reference syntax.
The statement ASSIGN f to <fs> assigns the field f to field
symbol <fs>. The field symbol <fs> then "points" to the
contents of field f at runtime. This means that all changes to the
contents of f are visible in <fs> and vice versa. You declare
the field symbol <fs> using the statement FIELD-SYMBOLS: <fs>.
Reference syntax
Programming languages such as PASCAL and C use a dereferencing symbol
to indicate the difference between a reference and the object to which
it refers; so PASCAL would use p^ for a pointer instead of p, C would
use *p instead of p. ABAP does not have any such dereferencing symbol.
**     In PASCAL or C, if you assign a pointer p1 to a pointer p2,
you force p1 to point to the object to which p2 refers (reference semantics).
**     In ABAP, if you assign a field symbol <fs1> to a field
symbol <fs2>, <fs1> takes the value of the data object to
which <fs2> refers (value semantics).
**     Field symbols in ABAP are always dereferenced, that is,
they always access the referenced data object. If you want to
change the reference yourself in ABAP, you can use the ASSIGN statement
to assign field symbol <fs1> to field symbol <fs2>.
Using field symbols
You declare field symbols using the FIELD-SYMBOLS statement.
They may be declared either with or without a specific type.
At runtime you assign a field to the field symbol using the ASSIGN
statement. All of the operations on the field symbol act on the field
assigned to it.
When you assign a field to an untyped field symbol, the field symbol
adopts the type of the field. If, on the other hand, you want to assign
a field to a typed field symbol, the type of the field and that of the
field symbol must be compatible.
A field symbol can point to any data object and from Release 4.5A,
they can also point to lines of internal tables.
The brackets (<>) are part of the syntax.
Use the expression <fs> IS ASSIGNED to find out whether the field
symbol <fs> is assigned to a field.
The statement UNASSIGN <fs> sets the field symbol <fs> so
that it points to nothing. The logical expression <fs>
IS ASSIGNED is then false. The corresponding negative expression
is IF NOT <fs> IS ASSIGNED.
An unassigned field symbol <fs> behaves as a constant with
type C(1) and initial value SPACE.
MOVE <fs>
TO dest     Transfers the initial value SPACE to the variable dest
MOVE 'A' to <fs>
Not possible, since <fs> is a constant
(runtime error).
To lift a type restriction, use the CASTING addition in the
ASSIGN statement. The data object is then interpreted as though
it had the data type of the field symbol. You can also do this
with untyped field symbols using the CASTING TYPE <type> addition.
The danger with pointers is that they may point to invalid areas.
This danger is not so acute in ABAP, because the language does not
use address arithmetic (for example, in other languages, pointer p
might point to address 1024. After the statement p = p + 10, it would
point to the address 1034). However, the danger does still exist, and
memory protection violations lead to runtime errors.
A pointer in ABAP may not point beyond a segment boundary. ABAP does
not have one large address space, but rather a set of segments.
Each of the following has its own segment:
*     All global data
*     All local data
*     Each table work area (TABLES)
*     Each COMMON PART
You should only let field symbols move within an elementary field or
structure where ABAP allows you to assign both within the global data
and beyond a field boundary.

Difference between Field symbols and work area for Internal tables

Hi,
In ECC versions we all know that we need to declare the internal tables without headerline, and for handling the internal tables we need to use exclusive work areas.
Currently i have an issue that we have been asked to use field symbols instead of work areas...can any one help me how to use the field symbols and also let me know how it will improve the performance of the program..
Thanks and Regards,
Kathir

Hi
DATA: WA TYPE ITAB.
LOOP AT ITAB INTO WA.
IF WA-FIELD = .....
ENDIF.
ENDLOOP.[(code]
FIELD-SYMBOLS <WA> TYPE ANY.
LOOP AT ITAB ASSIGNING <WA>.
ENDLOOP.
Now the problem is you can't know the name of the fields of the table at runtime, so you can't write:
IF <WA>-FIELD = .....
ENDIF.
Anyway you can create a field-symbols strcturated like the table:
[code]FIELD-SYMBOLS <WA> TYPE ITAB.
LOOP AT ITAB ASSIGNING <WA>.
IF <WA>-FIELD = .....
ENDIF.
ENDLOOP.
I don't know which are the differences for the performance between to use a field-symbol and to use a structure as work-area.
The differnce between the field-symbols and work-area is the field-symbol is assigned directly to the record, so u don't need to do a MODIFY statament to change something:
LOOP AT ITAB INTO WA.
WA-FIELD =
MODIFY ITAB FROM WA.
ENDLOOP.
LOOP AT ITAB ASSIGNING <WA>.
<WA>-FIELD =
ENDLOOP.
These two pieces of abap code do the same action, so probably the field-symbol improve the performance because it do an access directly to the record without to use an external structure as workarea.

Which is the difference between field mode and frame mode in interlacing?

Which is the best one for moving objects?

An interlacing camera actually takes two pictures to create each picture you see. These pictures are taken a fraction of a second apart, which allows the object of interest to move.
First, the camera takes a picture using the odd lines of the sensor. This is the first field. About 1/60 of a second later, it takes a picture using the even lines of the camera. This is the second field. The two pictures are combined by the frame grabber by interlacing the lines, which creates the frame you normally see as the image.
In frame mode, the two fields are combined to make a single image. In field mode, you get the odd lines as an image, and the even lines as a separate image.
When capturing a moving object, it is best to use a progressive scan (non-interla
ced) camera, which takes a picture using all of the lines simultaneously.
If you only have an interlaced camera, your best option is probably field mode, because the object doesn't have a chance to move. There are a couple of drawbacks to field mode, though. The height of your image is only half what it should be, which distorts everything and makes it difficult for measurements and the like. Also, the odd and even images are shifted by one line, so the live image appears to vibrate slightly if there is a lot of detail. You can't compare two consective images, because they are odd and even fields.
I hope this helps.

Finding difference between Max date and Min date from single date field

Dear Experts,
Here I am with a scenario where i didnt find any solution in SDN and in most threads it is unanswered.
I have 1 KF which is a date field. With reference to Serial no, I want to find out the Max and Min date from the same KF. I created 2 CKF where the same KF is used in both CKF to find the Min and Max dates,
Ex:
Serial No | Material | Actual Del date | Max | Min | Difference
0123 | 300012 | 01.01.2009 | 31.01.2009 | 01.01.2009 | 30
0123 | 300013 | 07.01.2009 | 31.01.2009 | 01.01.2009 | 30
0123 | 300018 | 15.01.2009 | 31.01.2009 | 01.01.2009 | 30
0123 | 300014 | 30.01.2009 | 31.01.2009 | 01.01.2009 | 30
0124 | 300019 | 02.01.2009 | 10.01.2009 | 02.01.2009 | 8
0124 | 300012 | 06.01.2009 | 10.01.2009 | 02.01.2009 | 8
0124 | 300017 | 10.01.2009 | 10.01.2009 | 02.01.2009 | 8
This is the way how I want the output where now I am able to get the values right till Max and Min and not the difference. I even created the 3rd CKF the find the difference but it is not working.
How can I find the difference between the Max and Min dates?
Regards,
Chan

Hi
You have FM --DAYS_BETWEEN_TWO_DATES you can use this while Customer Exit.
Try to Have 2 RKF for Min Data and Max Date and create a formula/CKF on the same ..

What is difference between sy-tabix and sy-index.

SAP Seniors,
Can you please let me know what is difference between sy-index and sy-tabix.
I read the SAP help, it is confusing for me. it looks like both are same from help. please help me.
Thank you
Anitha.

HI,
Here is a brief description of difference between SY_TABIX and SY_INDEX and using them with several conditions.
SY-TABIX
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY-INDEX
In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
Hope this helps.
Thank you,
Pavan.

What is difference between User Exits and BAPI

hello sap gurus
what is difference between User Exits and BAPIs

http://www.sap-img.com/abap/what-is-user-exits.htm
www.****************
Where as this customer exits are again divided into:
1. Menu Exits.
2. Field Exits.
3. Screen Exits.
4. Function module exits.
These all the things comes under Enhancements.
User exits
1.A user exit is a three character code that instructs the system to access a program during system processing.SXX: S is for standard exits that are delivered by SAP.
XX represents the 2-digit exit number.UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number
2.USER EXITS are FORMS and are called by SAP standard programs
using PERFORM.
3.Inside the form (user exit) you can read and change almost
any global data from host program.
4. User exits are more flexible because you have more information to use in your code but on the other hand , it is very easy to manipulate erroneously global data and lead the standard program to a dump or even to make database inconsistent.
5.While changing User-exit,Access Key is required,
BAPI is nothing function module but which is remote enabled, means you can access this fm through other SAP or non-SAP system by assingning to business object,which we can crea in SWO1 transaction.

What is difference between report programming and dialog programming?

hi,
what is difference between report programming and dialog programming? plz provide some example code
bye

ABAP programming
Basically reports are used to read database and represent the results in lists.
Reports are collections of processing blocks that the system calls depending on events.
We can use reports to evaluate data from database tables.
Reports are stand alone programs and controlled by events.
A report itself never creates events
steps in report:
Processing the selection screen
Reading the database
Evaluating the data and creating lists
Outputting a list.
1st u write simple logics, after that u can enhance the code as step by step.

Dialog Programming
Structure of a Dialog Program
A dialog program consists of the following basic components:
Screens (dynpros)
Each dialog in an SAP system is controlled by dynpros. A dynpro (DYnamic PROgram) consists of a screen and its flow logic and controls exactly one dialog step. The flow logic determines which processing takes place before displaying the screen (PBO-Process Before Output) and after receiving the entries the user made on the screen (PAI-Process After Input).
The screen layout fixed in the Screen Painter determines the positions of input/output fields, text fields, and graphical elements such as radio buttons and checkboxes. In addition, the Menu Painter allows to store menus, icons, pushbuttons, and function keys in one or more GUI statuses. Dynpros and GUI statuses refer to the ABAP/4 program that control the sequence of the dynpros and GUI statuses at runtime.
ABAP/4 module pool
Each dynpro refers to exactly one ABAP/4 dialog program. Such a dialog program is also called a module pool, since it consists of interactive modules. The flow logic of a dynpro contains calls of modules from the corresponding module pool. Interactive modules called at the PBO event are used to prepare the screen template in accordance to the context, for example by setting field contents or by suppressing fields from the display that are not needed. Interactive modules called at the PAI event are used to check the user input and to trigger appropriate dialog steps, such as the update task.
All dynpros to be called from within one transaction refer to a common module pool. The dynpros of a module pool are numbered. By default, the system stores for each dynpro the dynpro to be displayed next. This dynpro sequence or chain can be linear as well as cyclic. From within a dynpro chain, you can even call another dynpro chain and, after processing it, return to the original chain.

Difference between primary key and primary index

Dear All,
Hi... .Could you pls tell me the difference between primary key and primary index.
Thanks...

Hi,
Primary Key : It is one which makes an entry of the field unique.No two distinct rows in a table can have the same value (or combination of values) in those columns.
Eg: first entry is 111, if you again enter value 111 , it doesnot allow 111 again. similarly for the strings or characters or numc etc. Remember that for char or numc or string 'NAME' is not equal to 'name'.
Primary Index: this is related to the performance .A database index is a data structure that improves the speed of operations in a table. Indices can be created using one or more columns, providing the basis for both rapid random lookups and efficient ordering of access to records. The disk space required to store the index is typically less than the storage of the table (since indices usually contain only the key-fields according to which the table is to be arranged, and excludes all the other details in the table), yielding the possibility to store indices into memory from tables that would not fit into it. In a relational database an index is a copy of part of a table. Some databases extend the power of indexing by allowing indices to be created on functions or expressions. For example, an index could be created on upper(last_name), which would only store the uppercase versions of the last_name field in the index.
In a database , we may have a large number of records. At the time of retrieving data from the database based on a condition , it is a burden to the db server. so whenever we create a primary key , a primary index is automatically created by the system.
If you want to maintain indices on other fields which are frequently used in where condition then you can create secondary indices.
Reward points if helpful.
Thanks,
Sirisha..
