What is the functional specification

hai
sap gurus please tell me the functional specification how can we write the functional specification
can anbody explain in details and give me one good example for functional specification?
thanks

anwar

Functional Specification:
To speak at macro level that is at project manager or at senior levels. The Functional Spec (Specification) which is a comprehensive document is created after the (SRS) Software Requirements Document. It provides more details on selected items originally described in the Software Requirements Template. Elsewhere organizations combine these two documents into a single document.
The Functional Specification describes the features of the desired functionality. It describes the product's features as seen by the stake holders, and contains the technical information and the data needed for the design and development.
The Functional Specification defines what the functionality will be of a particular area that is to be precise a transaction in SAP terminology.
The Functional Specification document to create a detailed design document that explains in detail how the software will be designed and developed.
The functional specification translates the Software Requirements template into a technical description which
a) Ensures that the product feature requirements are correctly understood before moving into the next step that is technical development process.
b) Clearly and unambiguously provides all the information necessary for the technical consultants to develop the objects.
At the consultant level the functional specs are prepared by functional consultants on any functionality for the purpose of getting the same functionality designed by the technical people as most of the times the functionalities according to the requirements of the clients are not available on ready made basis.
Let me throw some light on documentation which is prepared before and in a project:
1) Templates
2) Heat Analysis -
3) Fit Gap or Gap Analysis
4) Business Process Design
5) Business Process Model
6) Business Change & Impact
7) Configuration Design, which is just 5 % of Total SAP- have different names -
8) Future Impact & Change Assessment
9) Functional Design (Module Wise)
10) Risk Assessment
11) Process Metrics and Many More-- Which has impact on Business and its work flow

Hi guru's what are the function modules are used in ALV

hi guru's what are the function modules are used in ALV

Hi vasu,
There are some function modules which will enable to produce the reports without much effort.
All the definitions of internal tables, structures and constants are declared in a type-pool called SLIS.
1. SIMPLE REPORT.
The important function modules are
a. Reuse_alv_list_display
b. Reuse_alv_fieldcatalog_merge
c. Reuse_alv_events_get
d. Reuse_alv_commentary_write
e. Reuse_alv_grid_display
A. REUSE_ALV_LIST_DISPLAY : This is the function module which prints the data.
The important parameters are :
I. Export :
i. I_callback_program : report id
ii. I_callback_pf_status_set : routine where a user can set his own pf status or change the functionality of the existing pf status
iii. I_callback_user_command : routine where the function codes are handled
iv. I_structure name : name of the dictionary table
v. Is_layout : structure to set the layout of the report
vi. It_fieldcat : internal table with the list of all fields and their attributes which are to be printed (this table can be populated automatically by the function module REUSE_ALV_FIELDCATALOG_MERGE
vii. It_events : internal table with a list of all possible events of ALV and their corresponding form names.
II. Tables :
i. t_outtab : internal table with the data to be output
B. REUSE_ALV_FIELDCATALOG_MERGE : This function module is used to populate a fieldcatalog which is essential to display the data in ALV. If the output data is from a single dictionary table and all the columns are selected, then we need not exclusively create the field catalog. Its enough to mention the table name as a parameter(I_structure name) in the REUSE_ALV_LIST_DISPLAY. But in other cases we need to create it.
The Important Parameters are :
I. Export :
i. I_program_name : report id
ii. I_internal_tabname : the internal output table
iii. I_inclname : include or the report name where all the dynamic forms are handled.
II Changing
ct_fieldcat : an internal table with the type SLIS_T_FIELDCAT_ALV which is
declared in the type pool SLIS.
C. REUSE_ALV_EVENTS_GET : Returns table of possible events for a list type
Parameters :
I. Import :
Et_Events : The event table is returned with all possible CALLBACK events
for the specified list type (column 'NAME'). For events to be processed by Callback, their 'FORM' field must be filled. If the field is initialized, the event is ignored. The entry can be read from the event table, the field 'FORM' filled and the entry modified using constants from the type pool SALV.
II. Export :
I_List_type :
0 = simple list REUSE_ALV_LIST_DISPLAY
1 = hierarchcal-sequential list REUSE_ALV_HIERSEQ_LIST_DISPLAY
2 = simple block list REUSE_ALV_BLOCK_LIST_APPEND
3 = hierarchical-sequential block list
REUSE_ALV_BLOCK_LIST_HS_APPEND
D. REUSE_ALV_COMMENTARY_WRITE : This is used in the Top-of-page event to print the headings and other comments for the list.
Parameters :
I. it_list_commentary : internal table with the headings of the type slis_t_listheader.
This internal table has three fields :
Typ : H header, S selection , A - action
Key : only when typ is S.
Info : the text to be printed
E. REUSE_ALV_GRID_DISPLAY : A new function in 4.6 version, to display the results in grid rather than as a preview.
Parameters : same as reuse_alv_list_display
This is an example for simple list.

some theory regarding alv:
This table tells ALV which events are processed by the caller by CALLBACK.
The table of possible events per list type can be initialized using the module REUSE_ALV_EVENTS_GET.
You can display the names of the constants in the type pools SLIS which represent the individual events using the individual test function in the function module
REUSE_ALV_EVENT_NAMES_GET. Only events with a form routine name are processed.
The table structure contains the fields:
IT_EVENTS-NAME
Name of the Callback event.
Possible Callback events:
Action
USER_COMMAND USING R_UCOMM LIKE SY-UCOMM RS_SELFIELD TYPE SLIS_SELFIELD
Process actions on the list
As this is a frequently-used Callback event, the form routine can also be passed directly in the interface in the IMPORTING parameter I_CALLBACK_USER_COMMAND.
PF_STATUS_SET USING RT_EXTAB TYPE SLIS_T_EXTAB
If a user list status is to be set, it must be done in the form routine assigned to this event. The ALV function codes, which must not be active, are in the Parameter RT_EXTAB. This table must be passed with the SET PF-STATUS command (with inactive user function codes as well, if necessary).
The STANDARD status of the function group SALV should be used as a template for a user-specific status.
As this is a frequently-used Callback event, its form routine can also be passed directly in the interface in the IMPORTING parameter I_CALLBACK_PF_STATUS_SET.
ITEM_DATA_EXPAND USING RS_SELFIELD TYPE SLIS_SELFIELD RFLG_ALL TYPE C
Only relevant for hierarchical-sequential lists using the layout parameter IS_LAYOUT-EXPAND_FIELDNAME of the structure IS_LAYOUT.
Exit for passing item entries (ITEM table) for a header record which was expanded interactively by the user.
RS_SELFIELD-TABINDEX contains the header table index for which the item entries are to be put in the global item output table (T_OUTTAB_SLAVE). The Callback is only called if ALV has no items for a header which is to be expanded.
RFLG_ALL is passed with 'X' if the user shows all items. The application must ensure that entries are not repeated in the item table. RS_SELFIELD is initial in this case.
CALLER_EXIT USING RS_DATA Is called at the beginning of the function module to make special settings. It is not usually used.
List processing events
IMPORTANT: The application Callback routine must not manipulate the internal output table and/or its header record. This restriction applies to all Callbacks which are called in the list output and run under the 'List processing events'.
TOP_OF_LIST no USING parameter. Information output at the start of the list
END_OF_LIST no USING parameter. Information output at the end of the list
TOP_OF_PAGE no USING parameter
Equivalent to the list processing TOP-OF-PAGE event
END_OF_PAGE no USING parameter. Not available for hierarchical-sequential lists.
Information output at the end of a page. This is only called for printing.
TOP_OF_COVERPAGE no USING parameter
The selection information and list status are output together (if they exist) on a separate page by default. See also the documentation of the parameters:
IS_PRINT-NO_COVERPAGE
IS_PRINT-NO_PRINT_SELINFOS
IS_PRINT-NO_PRINT_LISTINFOS
IS_LAYOUT-GET_SELINFOS
The user can format the header area of the 'cover page' himself or herself by specifying a Callback routine for this event.
END_OF_COVERPAGE no USING parameter
Analogously to TOP_OF_COVERPAGE the user can add other information to the information output by ALV (selection information, list status) at this event.
FOREIGN_TOP_OF_PAGE no USING parameter
The Top-of-page event is always processed in ALV and is only passed to the caller via the Callback mechanism. This is still the case if the caller, e.g. by a user action, processes a branch list which was not formatted by ALV (e.g. a popup with additional information about the list record selected and displayed by ALV).
In this case, top-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event top-of-page still occurs in ALV. When ALV notices a top-of-page which was not caused by an ALV output, the form routine in FOREIGN_TOP_OF_PAGE is called.
FOREIGN_END_OF_PAGE no USING parameter
The event end-of-page is always processed in ALV and only passed to the caller via callback. This is still the case, e.g. when the caller processes a details list which was not formatted by ALV (e.g. a popup with further information about selected list records which were displayed by ALV).
In this case, end-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event end-of-page still occurs in ALV. When ALV notices an end-of-page that was not caused by an ALV output, the form routine in FOREIGN_END_OF_PAGE is called.
BEFORE_LINE_OUTPUT USING RS_LINEINFO TYPE SLIS_LINEINFO
Output information before each output line. Should only be used in justified cases because it costs a lot of performance.
AFTER_LINE_OUTPUT USING RS_LINEINFO TYPE SLIS_LINEINFO
Output information after each output line. Should only be used in justified cases because it costs a lot of performance.
Internal use only
LIST_MODIFY USING R_TABNAME TYPE SLIS_TABNAME
R_INDEX LIKE SY-TABIX
R_INDEX_ITEM LIKE SY-TABIX
R_INDEX_SUM LIKE SY-TABIX
IT_EVENTS-FORM
Name of the form routine which should be called in the calling program at the event.
Field_catalog:
Field catalog with field descriptions
2.7.1. Description
Field catalog containing descriptions of the list output fields (usually a subset of the internal output table fields). A field catalog is required for every ALV list output.
The field catalog for the output table is built-up in the caller's coding. The build-up can be completely or partially automated by calling the REUSE_ALV_FIELDCATALOG_MERGE module
See also the documentation of the function module REUSE_ALV_FIELDCATALOG_MERGE.
The minimal field catalog is documented under 'default'. The caller can use the other optional parameters to assign output attributes to a field which differ from the default.
A field catalog need not be built-up and passed explicitly only under the following conditions:
The internal table to be output has the same structure as a Data Dictionary structure which is referred to in the internal table declaration using LIKE or INCLUDE STRUCTURE.
all fields in this structure are to be output
the structure name is passed to ALV in the parameter I_STRUCTURE_NAME.
See also the documentation of the IMPORTING paramter I_STRUCTURE_NAME.
Positioning
row_pos (row position)
value set: 0, 1 - 3
Only relevant if the list output is to be multi-line (two or three lines) by default.
A multi-line list can also be defined by the user interactively if the default list is one-line.
The parameter specifies the relative output line of the column in a multi-line list.
col_pos (column position)
value set: 0, 1 - 60
only relevant when the default relative column positions differ from the field catalog field sequence. The parameter specifies the relative column position of the field in the list output. The column order can be changed interactively by the user. If this parameter is initial for all field catalog entries, columns appear in the field catalog field sequence.
Identification
fieldname (field name)
value set: internal output table field name (required parameter)
Name of the internal output table field which is described by this field catalog entry
tabname (internal output table)
value set: SPACE, internal output table name
This parameter is used in 'manual' field catalog build-up only for hierarchical-sequential lists.
Name of the internal output table which contains the field FIELDCAT-FIELDNAME.
Data Dictionary reference
ref_fieldname (reference field name)
value set: SPACE, Data Dictionary field name
Name of the Data Dictionary field referred to.
This parameter is only used when the internal output table field described by the current field catalog entry has a reference to the Data Dictionary (not a program field), and the field name in the internal output table is different from the name of the field in the Data Dictionary. If the field names are identical, naming the Data Dictionary structure or table in the FIELDCAT-REF_TABNAME parameter is sufficient.
ref_tabname (reference table/structure field name)
value set: SPACE, name of a Data Dictionary structure or table
Structure or table name of the referred Data Dictionary field.
This parameter is only used when the internal output table field described by the current field catalog entry has a Data Dictionary reference (not a program field).
Reference to fields with currency/measurement unit
Each internal output table sum or quantity field whose decimal places are to be formatted appropriately for the unit in the list must follow the convention:
the field is of data type QUAN or CURR (internal type P) (the field must really have this physical data type. Overwriting the physical data type with the parameter FIELDCAT-DATATYPE has no effect)
There is a field in the internal output table which contains the associated unit.
There is also an entry in the field catalog for the unit field.
(If the unit is not to appear as a column in the list, and cannot be interactively displayed as a column, e.g. because it is always unambiguous and is therefore explicitly output by the caller in the list header, the field catalog units field entry can take the parameter FIELDCAT-TECH = 'X'.
The association of a value field to a unit affects the output as follows:
appropriate decimal places display for the unit
an initialized field with a link to a non-initial unit is output as '0' for the unit (if FIELDCAT-NO_ZERO is initial). When this field is summed, this unit affects whether the units are homogeneous.
an initialized field with a link to an initial unit is output as SPACE. When this field is summed, the unit SPACE does not affect the homogeneity of the units.
When non-initial fields with an initial unit are summed, the unit SPACE is considered to be a unit.
Link to currency unit
cfieldname (currency unit field name)
value set: SPACE, output table field name
Only relevant for amount columns with associated unit.
Name of the internal output table field containing the currency unit associated with the amount field FIELDCAT-FIELDNAME. The field in FIELDCAT-CFIELDNAME must have its own field catalog entry.
ctabname (internal currency unit field output table)
value set: SPACE, output table field name
only relevant for hierarchical-sequential lists
Name of the internal output table containing the FIELDCAT-CFIELDNAME field.
Link to measurement unit
qfieldname (measurement unit field name)
value set: SPACE, output table field name
only relevant for quantity columns with unit link.
Name of the internal output table field containing the measurement unit associated with the quantity field FIELDCAT-FIELDNAME.
The field in FIELDCAT-QFIELDNAME must have its own field catalog entry.
qtabname (internal measurement unit field output table)
value set: SPACE, output table field name
only relevant for hierarchical-sequential lists
Name of the internal output table containing the FIELDCAT-QFIELDNAME field.
Column output options
outputlen (column width)
value set: 0 (initial), n
For fields with a Data Dictionary link this parameter can be left initial.
For fields without a Data Dictionary link (program field) the parameter must be given the value of the desired field list output length (column width).
initial = column width is the output length of the referred Data Dictionary field (domain).
n = column width is n characters
key (key column)
value set: SPACE, 'X' 'X' = kex field (key field output in color)
Key fields can not be interactively hidden. Parameter FIELDCAT-NO_OUT must be left initial.
For exceptions see the documentation of the FIELDCAT-KEY_SEL parameter.
key_sel (hideable key column)
value set: SPACE, 'X'
only relevant when FIELDCAT-KEY = 'X'
Key field which can be hidden interactively.
The key column sequence cannot be changed interactively by the user.
The output is controlled by the FIELDCAT-NO_OUT parameter analogously to non-key fields.
no_out (field in field list)
value set: SPACE, 'X' 'X' = field is not displayed in the current list.
The user can interactively choose the field for output from the field list.
The user can display the contents of these fields at line level using the 'Detail' function.
See also the 'Detail screen' documentation of the parameter IS_LAYOUT.
tech (technical field)
value set: SPACE, 'X' 'X' = technical field
Field cannot be output in the list and cannot be displayed interactively.
Field can only be used in the field catalog (not in IT_SORT, ...).
emphasize (highlight columns in color)
value set: SPACE, 'X' or 'Cxyz' (x:'1'-'9'; y,z: '0'=off '1'=on)
'X' = column is colored with the default column highlight color.
'Cxyz' = column is colored with a coded color:
C: Color (coding must begin with C)
x: color number
y: bold
z: inverse
hotspot (column as hotspot)
value set: SPACE, 'X'
'X' = column cells are output as hotspots
fix_column (fix column)
value set: SPACE, 'X'
Not relevant for block lists (output of several lists consecutively)
'X' = column fixed (does not scroll horizontally)
All columns to be fixed must have this flag, starting from the left. If a column without this flag is output, only the columns to the left of this column are fixed. The user can change the column fixing interactively. See also the documentation of the Layout parameter
IS_LAYOUT-NO_KEYFIX of the IMPORTING paramter IS_LAYOUT.
do_sum (sum over column)
value set: SPACE, 'X' 'X' = a sum is to be calculated over this internal output table field.
This function can also be called by the user interactively.
no_sum (sums forbidden)
value set: SPACE, 'X' 'X' = no sum can be calculated over this field, although the data type of the field would allow summing.
input (column ready for input)
Function not available
Format column contents
icon
value set: SPACE, 'X' 'X' = column contents to be output as an icon.
The caller must consider the printability of icons.
symbol
value set: SPACE, 'X' 'X' = column contents are to be output as a symbol.
The internal output table column must be a valid symbol character.
The caller must consider the printability of symbols.
Symbols can usually be printed, but may not always be output correctly, depending on the printer configuration.
just (justification)
value set: SPACE, 'R', 'L', 'C'
Only relevant for fields of data type CHAR or NUMC
' ' = default justification for this data type
'R' = right-justified output
'L' = left-justified output
'C' = centered output
The justification of the column header always follows the justification of the columns. Independent justification of the column neader is not possible.
lzero (leading zeros)
value set: SPACE, 'X'
Only relevant for fields of data type NUMC
ALV outputs NUMC fields right-justified without leading zeros by default.
'X' = output with leading zeros
Note: If a NUMC field is output left-justified or centered by FIELDCAT-JUST, leading zeros are output. If the output of leading zeros is suppressed by a Data Dictionary reference ALPHA conversion exit, the output is always left-justified.
no_sign (no +/- sign) Only relevant for value fields
value set: SPACE, 'X' 'X' = value output without +/ sign
no_zero (suppress zeros) Only relevant for value fields
value set: SPACE, 'X' 'X' = suppress zeros
edit_mask (field formatting)
value set: SPACE, template
template = see documentation of WRITE formatting option USING EDIT MASK template
The output conversion conv can be made by template = '== conv'.
Texts
The following text parameters should be specified for program fields without a Data Dictionary reference. The texts are taken from the Data Dictionary for fields with a Data Dictionary reference. If this is not desired, the text parameters can also be specified. The Data Dictionary texts are then ignored. If the user changes the column width interactively, the column header text with the appropriate length is always used. The interactive function 'Optimize column width' takes account of both the field contents and the column headers: if all field contents are shorter than the shortest column header, the column width depends on the column header.
The 'long field label' is also used in display variant definition, sort, etc. popups.
seltext_l (long field label)
seltext_m (medium field label)
seltext_s (short field label)
reptext_ddic (header)
analogous to the Data element maintenance 'Header'
The specified text is not necessarily output in the list, an optimum among all texts is sought.
ddictxt (specify text)
value set: SPACE, 'L', 'M', 'S'
You can specify with values 'L', 'M', and 'S', the keyword that should always be used as column header. If the column width changes, no attempt is made in this case to find an appropriate header for the new output width.
Parameters for program fields without Data Dictionary reference
see also 'Text' parameters
datatype (data type)
value set: SPACE, Data Dictionary data type (CHAR, NUMC,...)
Only relevant for fields without Data Dictionary reference
Program field data type
ddic_outputlen (external output length)
value set: 0 (initial), n
Only relevant for fields without Data Dictionary reference whose output is nevertheless to be modified by a conversion exit.
Prerequisites:
FIELDCAT-EDIT_MASK = '==conv'
see also the documentation of the parameter FIELDCAT-EDIT_MASK
FIELDCAT-INTLEN = n
see also the documentation of the parameter FIELDCAT-INTLEN
n = external format field output length
The column width FIELDCAT-OUTPUTLEN need not be the same as the external format output length (FIELDCAT-DDIC_OUTPUTLEN).
intlen (internal output length)
value set: 0 (initial), n
Only relevant for fields without Data Dictionary reference whose output is nevertheless to be modified by a conversion exit.
Prerequisites:
FIELDCAT-EDIT_MASK = '==conv'
see also the documentation of the parameter FIELDCAT-EDIT_MASK
FIELDCAT-DDIC_OUTPUTLEN = n
see also the documentation of the parameter FIELDCAT-DDIC_OUTPUTLEN
n = internal format field output length
rollname (data element)
value set: SPACE, Data Dictionary data element name
F1 help can be provided for a program field without a Data Dictionary reference, or F1 help which differs from the Data Dictionary help can be provided for a field with a Data Dictionary reference, using this parameter.
When F1 help is called for this field, the documentation of the specified data element is displayed.
If the FIELDCAT-ROLLNAME is initial for fields with a Data Dictionary reference, the documentation of the data element of the referred Data Dictionary field is output.
Others
sp_group (field group key)
value set: SPACE, CHAR(1)
Field group key.
Keys are assigned to group names in the IT_SPECIAL_GROUPS parameter (see also the documentation of the parameter IT_SPECIAL_GROUPS).
When such an assignment is made in the field catalog and in IT_SPECIAL_GROUPS, the fields are grouped correspondingly in the display variant popup.
reprep (Report/Report interface selection criterion)
value set: SPACE, 'X'
Prerequisites:
The system contains the Report/Report interface (function group RSTI, table TRSTI)
Parameter LAYOUT-REPREP = 'X'
(see also the documentation of the parameter LAYOUT-REPREP of the IMPORTING parameter IS_LAYOUT )
'X' = When the Report/Report interface is called, the value of this field is passed in the selected interface start record as a selection criterion.
2.7.2. Default
The following entries are usually sufficient for internal table fields with a reference to a field defined in the Data Dictionary :
fieldname
ref_tabname
Notes:
ALV gets the remaining information from the Data Dictionary.
If no relative column position (COL_POS) is specified, the fields are output in the list in the order in which they were added to the field catalog.
REF_FIELDNAME need only be specifid when the name of the internal table field differs from the name of the referred Data Dictionary field.
Information which is explicitly entered in the field catalog is not overwritten by information from the Data Dictionary.
Priority rule:
Entries in the field catalog have priority over differing entries in the Data Dictionary.
The following entries are usually sufficient for internal table fields without a reference to the Data Dictionary (program fields):
fieldname
outputlen
datatype
seltext_s
seltext_m
seltext_l
Notes:
F1 help can be provided for program fields by assigning a data element to the parameter ROLLNAME.
If the parameters SELTEXT_S, SELTEXT_M, SELTEXT_L, and REPTEXT_DDIC contain appropriate field labels, the program field column headers are also adjusted appropriately when the column width changes

Please update the functional specifications for Vendor Balance Report

Dear All,
Please update the functional specifications for Vendor Balance Report with
proper descriptions.
Please include
1. How your selection screen should look like..
2. Output format ( in an excel sheet)
3. Logic for every field in the output format (viz. .. how do link the
vendors from the selection screen to the BKPf and BSEG tables, how do you
find open and closed items in BSEG , etc.)
Please avoid statements like 'The total value of all the break-up should
tally with the balance as shown in FBL1N for a given vendor for the given
day.'
You need to give the logic for the FBL1N, in that case.
Regards
Rama Mohan

Hello again,
Regarding having them update the specs, one can dream. Dreams are free. LOL. Hopefully the memory makers will update their specs as more makers start supporting a large memory configuration.
The 4GB sticks I am using are http://shop.kingston.com/partsinfo.asp?ktcpartno=KTL-TP667/4G
I did not do an extended test of the sticks in my MBP. Their home is in the ThinkPad I have because it is running Windows Server 2008 with Hyper-V.
As you can see from the link above, these little suckers are pricey. But consider the price of 2GB SoDIMMs were $950 when they entered the market a couple of years ago. The price will drop.
I asked the Kingston rep that sent these to me if online sites like newegg.com would have them soon. She indicated no, but the corporate buying sites like CDW and Zone would. So check around. They just started shipped a couple of weeks ago so be patient.
If you have any other questions, please stop by http://blogs.technet.com/keithcombs/archive/2008/07/05/testing-my-apple-macbook- pro-with-8gb-of-ram.aspx and ask there. I'll see them much more quickly.

What are the functions of tables in ods

Hi,

Hi,
new table holds the "new" loaded data in ODS. If you start a new request to load data in your ODS, it firstgoes to table new data. Then you normally activate data either manually or by process chain. Then the daa will be copied over from new to active table. The change log table holds the delta information, what will change during activation or which records will be overwritten with new data or which data is new at all.
With recordmode you can specify which update mode will be used or more excalty which delta mode will be used. SID is necessary for master data, because ODS will only hold the SID values of the used characteristivcs and not the characteristic values itselfs. It's part of normalization used in BI.
For more details I recommend to look here in SDN, go to a class or read help.sap.com pages.

What are the functional differences between the iPhone and the iPod Touch, barring of course the differences in service requirements.

What are the functional differences between the iPhone and the iPod Touch, barring of course the differences in service requirements.

For one, their form factors are slightly different as the iPhone has a bit more squarish body whereas the iPod Touch has a tapered back to it.
The iPhone also has much better front and rear cameras. Exact details as to the difference in megapixels depends on whether or not you talking about the iPhone 4 or 4S. If you would like to get more details, you can always view
each models specs on Apple's online store.
See here for a better explanation.

There is really no "best" setting here for the AirPort Express devices. If you need more wireless coverage in the area where an Express is located, then it makes sense to configure the Express to "extend" a wireless network.
If you already have good coverage in an area where an Express is located, then the "join" configuration makes sense.
I've yet to meet the first user who felt that he/she had too much wireless signal coverage in their home, but you never know.
