Query on differences between table Icons and types in smartforms

Hello,
I have a question regarding the apparent differences between tables in smartforms.
I have noticed on some of the default smartforms that are supplied the table icon is the same as on the
'Create new session' button at the top of a Sap session window. The icon on a table that I am currently working on is like a 'spread sheet' design, a heading with columns, as shown in the current documentation. The way the two styles of tables work is different.
Is the difference down to the fact one was created in an older implementation of Sap?
The reason I ask is because the table I refered to initially, is easier when configuring cells.
Regards
Mike.

Hello Karthik
Thanks for taking the time to reply to my question.
The difference in the icons but with essentially the same function has always confused me since starting Smartforms.
Thank you for enlightening me.
I asked the question because the Complex node has a feature that I could have used. I have managed though to solve my problem using a table node.
Ten points awarded.
Best Regards
Mike Spear.

What is difference between table space and shchema

what is difference between table space and shchema ?

784633 wrote:
so each user has it own space of tables - schema ?yes, but let's clarify a bit ....
The "schema" is the collection of all objects owned by a particular user. So if user SCOTT creates two tables, EMP and DEPT, and a view EMP_RPT, and a procedure GET_MY_EMP, those objects (tables, views, procedures) collectively make up the SCOTT schema.
Those objects will be physically stored in a tablespace.
A tablespace is a named collection of data files. So tablespace USERS will be made up of one or more data files. A specific datafile can belong to one and only one tablespace. If a tablespace has more than one data file, oracle will manage those files as a collection invisible to the application - much like the OS or disk subsystem handles striping across multiple physical disks.
A specific object in the SCOTT schema can exist in only one tablespace, but not all objects of the schema have to be in the same tablespace. Likewise a tablespace can contain objects from multiple schemas.
and can one user to access tables of other users?As others have said - FRED can access tables belonging to SCOTT as long has SCOTT has granted that access to FRED.

Difference between table CKMLKEPH and transaction figure of CKM3

Hi Gurus,
Having an issue in material ledger transaction and table data.
There is a difference between table CKMLKEPH and transaction figure of CKM3 for couple of periods.
Single level price difference for raw material domestic figure coming in transaction CKM3 is not matching with CKMLKEPH table.
Can you advice the tentative reason of it.
Thanks in advance,
MC.

Hi MC,
MLHELP_CCS_CONS_CHECK which check the actual CCS and the program
MLHELP_SPRICE_CCS_INIT for the standard CCS.
These programs are provided by the ML Helpdesk tool via note 364368.
Although these reports are used by SAP Support you can execute them in
test mode to verify your CCS data.

Difference between tables statement and by using type statement

Hi all,
I need to know the difference between the two of the below statements
Tables spfli.
and

As far as i know both seem same to me.
Thanks in advance,

this will create a work area (spfli), looks like DB table spfli, but the statement is obsolate
Bala Shanmuga Priyan wrote:

this will result in a syntax error, because this would also create a work area, but they cannot have header lines, so you should leave the WITH HEADER LINE addition.
To create work area use:
DATA : gw_spfli TYPE spfli.
To create internal table:
DATA : gt_spfli TYPE TABLE OF spfli.

Hi
HI,
INTERNAL Table and it's background:
===================================
Internal table acts as a container which is used to store the record sets. That is used to store the data fetched from the database table.
So due to performance reason every time access to database would not be so good and decrease the performance. So you just select the data from the database and store it in the intermediate table. This table is called INTERNAL TABLE. So it's an replica of the database. The design foes like this,
PRESENTATION SERVER <> APPLICATION SERVER <>
DATABASE SERVER.
So everytime gain accessing to database results in high resource usage and bad permformance.
So always play around with internal tables. So obviously the whenever you access the data in the INTERNAL TABLE, the application server will be used.
WORK AREA:
==========
When ever you loop at the internal table, the current record should be stored in a temporary work place. That is called WORK AREA.
LOOP AT ITAB INTO WORKAREA.
ENDLOOP.
ITAB :An internal table
WORKAREA:An instance of internal table

Purchasing - Difference Between Organisation Classification and type?

Hi All,
Whilst setting purchase organisation i was curious to know what is the difference between organisation type and organisation classification when creating organisation within Purchasing?
Any useful explanation will be welcomed

Hi Lavanya,
this choice boils down to the XML definition of Type an Element.
A type is not something concrete; meaning that it is merely a definition. You'll always need something of that type to put data in. In other words; if I only have a type, I'll need to create an element that is of that type in order to have something to work with.
For the messages it comes down to this: say, I've declared a type by the name of
<complexType name="arbitraryType">
<sequence>
<element name="contentGoesHere"/>
</sequence>
</complexType>
If I make the message of this type: it will look like this:
<MessageName>
<payload>
<contentGoesHere>
</payload>
</MessageName>
If I define an element as following:
<element name="arbitraryElement">
<complexType>
<sequence>
<element name="contentGoesHere"/>
</sequence>
</complexType>
</element>
and I put it in the message, it will look like this:
<MessageName>
<payload>
<arbitraryElement>
<contentGoesHere/>
</arbitraryElement>
</payload>
</MessageName>
Hope this clears up a little. Refer to w3.org for an exact definition of the two.
Cheers,
André

http://www.sapmaterial.com/tablecontrol_sap.html
Custom Controls
A custom control is an area on a screen. You create them in the Screen Painter, and, like all other screen objects, they have a unique name. You use custom controls to embed controls. A control is a software component on the presentation server, which can be either an ActiveX control or a JavaBean, depending on the SAPgui you are using. They allow you to perform tasks, such as editing texts, locally on the presentation server. The control is driven by the application logic, which still runs on the application server.
The SAP Control Framework
The controls on the presentation server and the ABAP application programs on the application server communicate using the Structure link SAP Control Framework. This is programmed in ABAP Objects, and contains a set of global classes that you can find in the Class Browser under Basis ® Frontend services. These classes encapsulate the communication between the application server and presentation server, which is implemented using Remote Function Call.
All application controls are encapsulated in a global class. You can find the SAP Basis controls in the Class Browser under Basis ® Frontend Services or Basis ® Component Integration. Programs that use controls on a screen work with the methods and events of the global classes that encapsulates them.
Container Controls
Before you can work with a custom control on a screen, you must assign a Structure link SAP Container Control to it. Container controls are instances of special global classes from the SAP Control Framework. The global class for custom controls is called CL_GUI_CUSTOM_CONTAINER. To link a custom control to a container control, pass the custom control name to the CONTAINER_NAME parameter of the container control constructor when you instantiate it.
As well as using custom containers, you can link controls to a screen using a SAP Docking Container. This is encapsulated in the global class CL_GUI_DOCKING_CONTAINER. The SAP Docking Container does not place the control within a screen. Instead, it attaches it to one of the four edges. You can nest containers. For example, you can use the SAP Splitter Container (classes CL_GUI_EASY_SPLITTER_CONTAINER or CL_GUI_SPLITTER_CONTAINER) within other containers. This allows you to split a custom control or docking control into more than one area, allowing you to embed more than one control.

Difference between Generic extraction and Generic Delta

Hi Experts,
Pleasee give of some information below query:
1) Difference between Generic extraction and Generic Delta.
2) How to achieve Generic delta.
3) When we go for Generic delta instead of generic extraction.
Advance ThankU. Points vl be assigned.
Thanks,
Ragu.R

Hi,
Generic delta is the delta load done using Generic DS.
Generic extraction
Usage:
1. When the standard extractors are not supporting the extraction what you need. If SAP does not have a standard extractor for your need to get data from R3, you would have to go for generic extractor.
2. If you create a custom object say by combining certain base tables in R3 say custom tables ZTAB1 and ZTAB2. These two tables are not SAP provided tables and there will not be any standard extractors. So cases like this you will have to go for generic extractors.
How:
You have to use RSO2 transaction and you can also set delta based on, one of the three characteristics such as timestamp, calday or pointer (a sequence no).
once you create it and activate it. The extractor will be available in ROOSOURCE - (table in R3 where all the data sources are available).

Difference between Table and Table Type

Hi
Can you please let me know the
Difference between Table and Table Type and
Difference between Structure and Table Type?
Regards,
Sree

hi,
table is a data dictionary object in sap. table is of different types
1. transparent tables
2. pool tables
3. cluster tables
table type gives option for u to select different types of internal tables. they r
1. standard table
2. sorted table
3. hash table
Structures :
-Defined like a table and can then be addressed from ABAP programs.
-Structures contain data only during the runtime of a program.
-Just like user-defined data type.
- they are not present in database server and only on application server.
if helpful reward some points.
with regards,
Suresh Aluri.

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.

What's the difference between segment filtering and reduced message type

Hi gurus,
What's the difference between segment filtering and reduced message type? It seems they have the same functionality: Reduce the segment while idoc is generated.
Thanks in advance.

Hi,
BD53 is for IDoc Reduction.
this allows you to create a reduced message based upon a standard message type.If you want see mandatory fields. go to T-coe BD53 and give one standard messege type name and eg: matmas
there mandatory fields will be in Green color..
And BD56- This transaction is used to filter out segments of IDocs for combination of sender and receiver. This is usefull in scenarios where a standard IDoc with many segments is used but the receiving partner is only interested in some of the segments
the table related to this transation is TBD20
please go through below blog you have an idea abt that,

Difference between fully-specified data types. and generic types

Hi,
Can anyone tell me the difference between fully-specified data types and generic types.
Thanks in advance.
Regards,
P.S.

HI
Generic table types
INDEX TABLE
For creating a generic table type with index access.
ANY TABLE
For creating a fully-generic table type.
Data types defined using generic types can currently only be used for field symbols and for interface parameters in procedures . The generic type INDEX TABLEincludes standard tables and sorted tables. These are the two table types for which index access is allowed. You cannot pass hashed tables to field symbols or interface parameters defined in this way. The generic type ANY TABLE can represent any table. You can pass tables of all three types to field symbols and interface parameters defined in this way. However, these field symbols and parameters will then only allow operations that are possible for all tables, that is, index operations are not allowed.
Fully-Specified Table Types
STANDARD TABLE or TABLE
For creating standard tables.
SORTED TABLE
For creating sorted tables.
HASHED TABLE
For creating hashed tables.
Fully-specified table types determine how the system will access the entries in the table in key operations. It uses a linear search for standard tables, a binary search for sorted tables, and a search using a hash algorithm for hashed tables.
