Field Symbols
http://help.sap.com/saphelp_46c/helpdata/EN/fc/eb387a358411d1829f0000e829fbfe/frameset.htm
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.

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>.

Hai,
Generally, we use the explicit work area to process the internal table like appending & modifying records. We can reduce the time and improve the performance of the program by using the field-symbols. When we use the LOOP construct with the explicit work area, system need to engage the resources to put the required record in the work area, process it and move it back to the table if the needed. This additional processing time could be saved by using the field-symbol. By using the field-symbols we can save this additional time and improve the performance. Field-symbols are similar to dereferenced pointers in C. While using the field-symbol, system uses the same memory allocated to that particular field in the record instead of moving it to work area and processing

I have an apple tv 1st generation, and there is a setting for airtunes. can someone tell me what this is and how to use it?

I've looked at that, but on my PC, "look for remote speakers connected with airtunes" isn't an option.
The only options I get are "prevent ipods [etc] from syncing automatically" , "warn me when [X %] of the data on this computer will be changed" and "forget all remotes". Its also got a list of backups I have saved, as well as a button to reset sync history.
When I am playing a song, the "airplay" button isn't even visible.
I am sure that the apple tv setting is on as well. Is there anything else you can help me with?

I am a professional photographer of many years standing and at the moment I have a student for 12 months, who I am teaching how to use various Adobe programs, but to introduce her to video editing, I have purchased Adobe Premier Elements 13 which is less complicated than the Premier Pro that I use. The program works perfectly, except for one thing.... when adding a title to the short video sequence we are working with, if I use a particular font (Metallophile Sp8) which I obtained from my Adobe Typekit, it crashes the program,.... all other fonts work perfectly....can anybody help me please?

clivephoto
What computer operating system is your Premiere Elements 13 running on? And what video card/graphics card does this computer use?
From your description, can I assume that this Mettallophile Sp8 font is being recognized by Premiere Elements 13 to the extent
that it can be seen and remains seen in Titler's list of font choices - even after the crashes?
If you opened a new project, imported nothing, and created a text title in the Titler with this Mettallophile Sp8 font, does the program crash?
Please review the following which discuss fonts and Premiere Elements and determine if anything in it helps.

Very Urgent: how to define field symbols in class using se24 Points assured

hi all
I am new to abap oo programming. I am using se24 to build a class
where some methods have code which involves working with field sybmols but i am not able to figure out way for how to define field symbols in the attributes section.
I tried defining like : fld_sym type ref to dbtab-fld
but in the method implementation if i try to use it like assign fld to <fld_sym> there it says fld_sym is not defined as a field symbol.
So can anyone please guide me how to define field symbols in se24.
Also what should be the general steps while creating a class using se24.
Points assured
thanks

Using Field symbol to fetch data from another program

I have a requirement where i need to fetch value of a field from one of the function pool so i have written a sample progam to check the logic but its doest seems to work its giving dump.
Basically i want to know how to use <programname><fieldname> with fieldsymbol.
REPORT ztest1.
DATA test(25) VALUE 'ggg'.
submit ztest.
report ztest.
constants: lv_memory(25) type c value '(ZTEST1)TEST'.
field-symbols: <fs2> type char25 .
assign (lv_memory) to <fs2>.
write : <fs2>.
I am getting same field symbol assignment dump

Hi Rahul,
You can use this concept in between the FUNCTION MODULES where both are
under same FUNCTION GROUP ( as both the FM's have same global memory area ).
And also if you are calling an FM or method from your program ,you can have the data of the calling program in that called FM or METHOD.
Hope this may help you.

What is field symbols?

Hi all,
Can anyone explains what is Fiels symbol and significance of that with examples?
Thanks

HI Shiva
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. (For more information, see Data References).
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
To declare a field symbol, use the statement
FIELD-SYMBOLS <FS> [<type>|STRUCTURE <s> DEFAULT <wa>].
For field symbols, the angle brackets are part of the syntax. They identify field symbols in the program code.
If you do not specify any additions, the field symbol <FS> can have data objects of any type assigned to it. When you assign a data object, the field symbol inherits its technical attributes. The data type of the assigned data object becomes the actual data type of the field symbol.
Note: it is possible to assign reference variables and structured data objects to untyped field symbols. However, the static field symbol is only a pointer to the field in memory, and does not have the complex type attributes of a reference or structured field until runtime. You can only use the field symbol to address the whole field (for example, in a MOVE statement). Specific statements such as CREATE OBJECT <FS> or LOOP AT <FS> are not possible.
Typing Field Symbols
The <type> addition allows you to specify the type of a field symbol. When you assign a data object to a field symbol, the system checks whether the type of the data object you are trying to assign is compatible with that of the field symbol. If the types are not compatible or convertible, the system reacts with a syntax or runtime error. If however, you want to assign the type of the field symbol to the data object by means of casting, you must do so explicitly using the ASSIGN statement. The system then treats the assigned data object as if it had the same type as the field symbol.
You specify the type of a field symbol using the same semantics as for formal parameters in procedures. For <type> you can enter either TYPE <t> or LIKE <f>. You can specify the type either generically or in full. If you specify a generic type, the type of the field symbol is either partially specified or not specified at all. Any attributes that are not specified are inherited from the corresponding data object in the ASSIGN statement. If you specify the type fully, all of the technical attributes of the field symbol are determined when you define it. You can then only assign data objects to it that have exactly the same data type.
You should always specify a type for each field symbol. If you cannot avoid defining a generic field symbol, make this clear by using an appropriate generic type declaration.
Generic Type Specification
The following types allow you more freedom when using actual parameters. The data object only needs to have the selection of attributes specified.
Typing
Check for data object
No type specification
TYPE ANY
All types of data object are accepted. The field symbol adopts all of the attributes of the data object.
TYPE C, N, P, or X
Only data objects with type C, N, P, or X are accepted. The field symbol adopts the field length and DECIMALS specification (type P) of the data object.
TYPE TABLE
The system checks whether the data object is a standard internal table. This is a shortened form of TYPE STANDARD TABLE (see below).
TYPE ANY TABLE
The system checks whether the data object is an internal table. The field symbol inherits all of the attributes (line type, table type, key) from the data object.
TYPE INDEX TABLE
The system checks whether the data object is an index table (standard or sorted table). The field symbol inherits all of the attributes (line type, table type, key) from the data object.
TYPE STANDARD TABLE
The system checks whether the data object is a standard internal table. The field symbol inherits all of the remaining attributes (line type, key) from the data object.
TYPE SORTED TABLE
The system checks whether the actual parameter is a sorted internal table. The field symbol inherits all of the remaining attributes (line type, key) from the data object.
TYPE HASHED TABLE
The system checks whether the actual parameter is a hashed internal table. The field symbol inherits all of the remaining attributes (line type, key) from the data object.
If you specify a type generically, remember that the attributes inherited by the field symbol from the program are not statically recognizable in the program. You can, at most, address them dynamically.
TYPES: BEGIN OF line,
         col1 TYPE c,
         col2 TYPE c,
       END OF line.
DATA: wa TYPE line,
      itab TYPE HASHED TABLE OF line WITH UNIQUE KEY col1,
      key(4) TYPE c VALUE 'COL1'.
FIELD-SYMBOLS <fs> TYPE ANY TABLE.
ASSIGN itab TO <fs>.
READ TABLE <fs> WITH TABLE KEY (key) = 'X' INTO wa.
The internal table ITAB is assigned to the generic field symbol <FS>, after which it is possible to address the table key of the field symbol dynamically. However, the static address
READ TABLE <fs> WITH TABLE KEY col1 = 'X' INTO wa.
is not possible syntactically, since the field symbol does not adopt the key of table ITAB until runtime. In the program, the type specification ANY TABLE only indicates that <FS> is a table. If the type had been ANY (or no type had been specified at all), even the specific internal table statement READ TABLE <FS> would not have been possible.
If you adopt a structured type generically (a structure, or a table with structured line type), the individual components cannot be addressed in the program either statically or dynamically. In this case, you would have to work with further field symbols and the method of assigning structures component by component.
Specifying the Type Fully
When you use the following types, the technical attributes of the field symbols are fully specified. The technical attributes of the data objects must correspond to those of the field symbol.
Typing
Technical attributes of the field symbol
TYPE D, F, I, or T
The field symbol has the technical attributes of the predefined elementary type
TYPE <type>
The field symbol has the type <type>. This is a data type defined within the program using the TYPES statement, or a type from the ABAP Dictionary
TYPE REF TO <cif>|DATA
The field symbol is a reference variable for the class or interface <cif>, or for a data object.
TYPE LINE OF <itab>
The field symbol has the same type as a line of the internal table <itab> defined using a TYPES statement or defined in the ABAP Dictionary
LIKE <f>
The field symbol has the same type as an internal data object <f> or structure, or a database table from the ABAP Dictionary
When you use a field symbol that is fully typed, you can address its attributes statically in the program, since they are recognized in the source code. If you fully specify the type of a field symbol as a reference or structured data object, you can address it as you would the data object itself, once you have assigned an object to it. So, for example, you could address the components of a structure, loop through an internal table, or create an object with reference to a field symbol.
REPORT demo_field_symbols_type .
DATA: BEGIN OF line,
         col1(1) TYPE c,
         col2(1) TYPE c VALUE 'X',
       END OF line.
FIELD-SYMBOLS <fs> LIKE line.
ASSIGN line TO <fs>.
MOVE <fs>-col2 TO <fs>-col1.
The field symbol <FS> is fully typed as a structure, and you can address its components in the program.
Attaching a structure to a field symbol
The STRUCTURE addition forces a structured view of the data objects that you assign to a field symbol.
FIELD-SYMBOLS <FS> STRUCTURE <s> DEFAULT <f>.
The structure <s> is either a structured local data object in the program, or a flat structure from the ABAP Dictionary. <f> is a data object that must be assigned to the field symbol as a starting field. However, this assignment can be changed later using the ASSIGN statement.
When you assign a data object to the field symbol, the system only checks that it is at least as long as the structure. You can address the individual components of the field symbol. It has the same technical attributes as the structure <s>.
If <s> contains components with type I or F, you should remember the possible effects of alignment. When you assign a data object to a field symbol with a structure, the data object must have the same alignment, otherwise a runtime error may result. In such cases, you are advised to assign such data objects only to structured field symbols, which retain the same structure as the field symbol at least over the length of the structure.
The STRUCTURE is obsolete; you should no longer use it. Field symbols defined using the STRUCTURE addition are a mixture of typed field symbols and a utility for casting to either local or ABAP Dictionary data types. If you want to define the type of a field symbol, include the TYPE addition in a FIELD-SYMBOLS statement. If you want to use casting, include the CASTING addition in an ASSIGN statement.
Example using the obsolete STRUCTURE addition:
DATA: wa(10) VALUE '0123456789'.
DATA: BEGIN OF line1,
         col1(3),
         col2(2),
         col3(5),
      END OF line1.
DATA: BEGIN OF line2,
         col1(2),
         col2 LIKE sy-datum,
      END OF line2.
FIELD-SYMBOLS: <f1> STRUCTURE line1 DEFAULT wa,
               <f2> STRUCTURE line2 DEFAULT wa.
WRITE: / <f1>-col1, <f1>-col2, <f1>-col3,
       / <f2>-col1, <f2>-col2.
Example using the correct syntax (TYPE and CASTING):
DATA: wa(10) VALUE '0123456789'.
DATA: BEGIN OF line1,
         col1(3),
         col2(2),
         col3(5),
      END OF line1.
DATA: BEGIN OF line2,
         COL1(2),
         COL2 LIKE sy-datum,
      END OF line2.
FIELD-SYMBOLS: <f1> LIKE line1.
ASSIGN wa TO <f1> CASTING.
FIELD-SYMBOLS: <f2> LIKE line2.
ASSIGN wa TO <f2> CASTING.
WRITE: / <f1>-col1, <F1>-col2, <F1>-col3,
       / <f2>-col1, <F2>-col2.
In both cases, the list appears as follows:
012 34 56789
01 2345/67/89
This example declares two field symbols to which different structures are attached. The string WA is then assigned to each of them. The output shows that the field symbols assign the strings component by component according to the type of the components.
Assigning Components of Structures to a Field Symbol
For a structured data object <s>, you can use the statement
ASSIGN COMPONENT <comp> OF STRUCTURE <s> TO <FS>.
to assign one of its components <comp> to the field symbol <FS>. You can specify the component <comp> either as a literal or a variable. If <comp> is of type C or a structure that has no internal tables as components, it specifies the name of the component. If <comp> has any other elementary data type, it is converted to type I and specifies the number of the component. If the assignment is successful, SY-SUBRC is set to 0. Otherwise, it is set to 4.
This statement is particularly important for addressing components of structured data objects dynamically. If you assign a data object to a field symbol either generically or using casting, or pass it generically (or using casting) to the parameter interface of a procedure, you cannot address its components either statically or dynamically. Instead, you must use the above statement. This allows indirect access either using the component name or its index number.
DATA: BEGIN OF LINE,
        COL1 TYPE I VALUE '11',
        COL2 TYPE I VALUE '22',
        COL3 TYPE I VALUE '33',
      END OF LINE.
DATA COMP(5) VALUE 'COL3'.
FIELD-SYMBOLS: <F1>, <F2>, <F3>.
ASSIGN LINE TO <F1>.
ASSIGN COMP TO <F2>.
DO 3 TIMES.
ASSIGN COMPONENT SY-INDEX OF STRUCTURE <F1> TO <F3>.
WRITE <F3>.
ENDDO.
ASSIGN COMPONENT <F2> OF STRUCTURE <F1> TO <F3>.
WRITE / <F3>.
The output is:
11         22         33
33
The field symbol <F1> points to the structure LINE, <F2> points to the field COMP. In the DO loop, the components of LINE are specified by their numbers and assigned one by one to <F3>. After the loop, the component COL3 of LINE is specified by its name and assigned to <F3>. Note that ASSIGN COMPONENT is the only possible method of addressing the components of <F1>. Expressions such as <F1>-COL1 are syntactically incorrect.

Field-Symbols: How to retrieve data into an internal table from FS

Hello All,
I am working on field symbols.I have declared the field symbols as shown.
FIELD-SYMBOLS: <gt_pos_data> TYPE table,
                           <wa_pos_data> like <gt_pos_data>.
Data: Begin of itab occurs 0,
           field1(5) type c,
           field2(10)_type c,
         end of itab.
The FS <gt_pos_data> has 100 fields but I need to move only two fields from this FS to my internal table itab.I am doing the following.
loop at <gt_pos_data> assigning <wa_pos_data>.
itab-field1 = <wa_pos_data>-field1.
itab-field2 = <wa_pos_data>-field2.
append itab.
clear itab.
endloop.
But it is giving me an error saying "<wa_pos_data> is a table without header line and therefore has no componet FIELD1".How to achieve this requirement?
Thanks in advance
Sandeep

<wa_pos_data> should be defined LIKE LINE OF <gt_pos_data>, but it will still have no structure, so you need to assign a field symbol to the component as well.
FIELD-SYMBOLS: <gt_pos_data> TYPE table,
                           <wa_pos_data> like LINE OF <gt_pos_data>,
                           <field> type any.
Data: Begin of itab occurs 0,
field1(5) type c,
field2(10)_type c,

VPN. What's this and how to use it?

Hello,
Recently I started to work from home and not the office. To connect to my work server my company's sysadmin sent me the requisites to connect to VPN (I need to ssh to my work server but it's allowed to the limited set of IPs). But I have no idea what to do next. How to set up the connection and how to use it?
Thanks

Thanks! I've tried to follow the steps described in the wiki article but unfortunately stucked on 'Making Your Connection' section:

What is access sequence tables and how to use them in program?

hi all, I know a little about SD and access sequence tables, but I get a requriment like this:
condition type is a paramater
The condition types allowed in this report are: Note: A list of pre-defined condition types with their corresponding access sequence tables will be defined.
How can I make it? How can I use it in program to get the price?

Hi,
An access sequence is a search strategy with the aid of which the SAP
System searches for valid condition records of a certain condition type.
For example, you can stipulate for a price that the SAP System first
searches for a price for a specific plant, and then for a generally
applicable price.
For condition types for which you wish to maintain conditions with their
own validity period, you must assign an access sequence. With this, you
define which fields the SAP System checks in searching for a valid
condition record.
e.g. When you create condition record (e.g. Purchasing condition record) you enter condition type, system asks you the key combination to enter the entries. These key combinations are nothing but the access sequence. On the basis of combination of condition table it will search record. e.g. when u maintain condition record with acc seq Material/plant combination, it will transfer the same record in PO when u enter same material and plant in the PO.
Example:
An access sequence has been assigned to condition type PB00 so that
prices can be maintained in purchasing info records and contracts.
No access sequence has been assigned to condition type RC00 because it
does not have a validity period of its own. In the standard system, it is
always maintained simultaneously with the price and is valid for the
period of the price.
