What is the function of show tab bar in safari setting?

this tool is in setting > safari > show tab bar on/off
any one know how it work

Hey Samooo205,
I see that you have some questions about the tab bar in Safari. Some information about this can be found in the following article:
Safari 7 (Mavericks): Customize the Safari window
http://support.apple.com/kb/PH17153
If you need help visually identifying the tab bar, you can find that information here:
Safari 8 (Yosemite): View webpages in tabs
http://support.apple.com/kb/PH19261
As it said in the first article, the tab bar option that you are wondering about only affects the behavior of the tab bar when there is only one tab open. If there are multiple tabs open, the tab bar will be shown, regardless of this setting. Thanks for using the Apple Support Communities!
Cheers,
Braden

  • Always show tab bar - Safari 3 - Leopard

    Hey. I recently lost all of my Home Folder's files, and now Safari 3 in Leopard does not allow me to always show the tab bar. I look in preferences, and the option is not there.
    How do I enable to always show the tab bar?

    Hi
    Welcome to Apple Discussions
    Go to the View Menu>Show Tab Bar or Shift/Command/T keys to show or hide. Tabs need to be enabled in your Safari Preferences>Tabs.
    As you have a new Safari Preference file, besides resetting the preferences in the preference panel, you'll need to reset any custom options, such as spelling in the Edit Menu or the various options in the View Menu. Also, additional icons can be added via View>Customize Toolbar via Drag/Drop on the ToolBar.

  • 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.

    I'm sure others will chime in with other things as well.

  • The "Always show tab bar" setting keeps unchecking itself.

    I'm using Firefox 4 on multiple machines all running windows 7 and synchronized with built in Sync and one instance on Android. I've noticed sometimes when closing all but the last tab that no tabs show in the tab bar (which is on top, I like that!). I go into "options" - "tabs" and see that "always show tab bar" is unchecked. I check it and get back to daily routines, only few days later the same thing happens again. By the way, I've noticed the same on my girlfriend's computer, also running windows 7, but not synchronized to any other computers. It's not a disaster, just annoying when it happens- as if someone sneaked in and changed my settings. Please help. Thanks.

    First check to make sure that an add-on is not interfering with behavior, to do that follow the procedure in the [[troubleshooting extensions and themes]] article.
    If it is not caused by an add-on, as a test you can create a new profile. Firefox stores user data and in profiles, creating a new profile will confirm if there is a problem with your current profile. See [http://kb.mozillazine.org/Creating_a_new_Firefox_profile_on_Windows Creating a new Firefox profile on Windows]. If the new profile works, you can [http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox transfer data and settings to the new profile]. It is best not to copy he preferences file (prefs.js) to the new profile as a setting stored in it may be causing the problem.

  • What is the use of confirmation tab in Purchase order ?

    what is the use of confirmation tab in Purchase order?

    Hello Balaji
    In Purchasing, the term Confirmation is an umbrella term for various kinds of information provided by a vendor to a customer with regard to ordered goods.
    Possible types of confirmation include the following:
    Order acknowledgments
    Loading or transport confirmations
    Shipping notifications. (Note that shipping notifications may also be referred to by a number of other names, including "advice (note)", "advice of dispatch", "ship notice", and "advance(d) shipping notice" ("ASN").)
    A further form of confirmation frequently used in Purchasing is the Inbound Delivery, which is created on the basis of an incoming shipping notification. The shipping notification represents a vendor’s confirmation to a purchasing organization of a delivery date for a certain quantity of ordered materials (or the date of performance of ordered services).
    You can enter incoming vendor confirmations manually. Alternatively, you can receive them via EDI and have them processed automatically.
    When working with vendor confirmations, you have the following options:
    You can enter the order acknowledgment number if you simply wish to provide a basis for monitoring the receipt or non-receipt of acknowledgments.
    You should enter the confirmed quantities and delivery dates if you wish to provide more detailed information in support of the purchasing, inventory management, and materials planning/control functions within your enterprise.

  • 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.

    C. REUSE_ALV_BLOCK_LIST_HS_APPEND
    D. REUSE_ALV_BLOCK_LIST_DISPLAY
    A. REUSE_ALV_BLOCK_LIST_INIT
    Parameters:
    I. I_CALLBACK_PROGRAM
    II. I_CALLBACK_PF_STATUS_SET
    III. I_CALLBACK_USER_COMMAND
    This function module is used to set the default gui status etc.
    B. REUSE_ALV_BLOCK_LIST_APPEND
    Parameters :
    Export :
    I. is_layout : layout settings for block
    II. it_fieldcat : field catalog
    III. i_tabname : internal table name with output data
    IV. it_events : internal table with all possible events
    Tables :
    i. t_outtab : internal table with output data.
    This function module adds the data to the block.
    Repeat this function for all the different blocks to be displayed one after the other.
    C. REUSE_ALV_BLOCK_LIST_HS_APPEND
    This function module is used for hierarchical sequential blocks.
    D. REUSE_ALV_BLOCK_LIST_DISPLAY
    Parameters : All the parameters are optional.
    This function module display the list with data appended by the above function.
    Here the functions REUSE_ALV_FIELDCATALOG_MERGE, REUSE_ALV_EVENTS_GET, REUSE_ALV_COMMENTARY_WRITE can be used.

    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

  • Cannot disable "always show tab bar" in FF 28.0?

    FF 19 had an option to deselect "always show tab bar" so that the tab bar is shown only when 2 or more tabs are open.
    FF 28 seems to always show the tab bar. I don't see any way to disable that (unless 2 or more tabs are open).
    How can I coerce FF 28 to not show tab bar unless 2 or more tabs are open?

    waka wrote: "In Firefox 23 and up, as part of an effort to simplify the Firefox options set and facilitate future improvements to Firefox, the option to hide the tab bar was removed. Fortunately, this can easily be resolved if you desire the keep tabs hidden. You can install "Hide tab bar with one tab", an extension hosted on Mozilla's add-ons site".
    That definitely "helps" insofar as you addressed my question dispositively.
    However, I do not agree with the decision. How does removing one option substantially "simplify" things? How does forcing me to install an add-on "simplify" things for me, the customer?
    FYI, I few add-ons as potential risks and a definite maintenance headache. A GUI add-on is probably more susceptible to compatibility issues.
    If you want to "simplify" the GUI by removing one option from a menu (that isn't very "busy" in the first place; klunk!), at least provide an about:config option to control this behavior.
    As for "facilitating future improvements", that is not my concern, a customer. Everything is SMOP.
    I was in product development and maintenance for 35 years, and we always put the customer first. One of our cardinal rules was: do not remove a feature unless it is a security risk; and even then, we might leave an option to re-enable the feature "at your own risk".
    Oh well, I'm probably p.i.s.s.ing into the wind. But thanks again for an accurate response.
