Service Parameters (SAP Library - ALV Grid Control (BC-SRV-ALV))

Service Parameters

The service parameters of the MiniALV service allow you to control the contents, personalization and the visual attributes of the MiniALV. For both MiniALV versions available (Workplace delivery and standard delivery), the service parameters always have the same status. Except for the following restriction, the service parameters of Basis delivery 6.10 and Workplace delivery 3.10 are identical:

Caution

The Workplace version of the MiniALV does not support the display of SAP Query reports in the MiniALV. The service parameters query , usergroup and workspace can therefore only be used in the Standard MiniALV.

To display data in the MiniALV, you must at least assign a value to the service parameter report . The MiniALV can also be started with a layout or report variant (with service parameter layout or variant ). If the MiniALV does not display any data, proceed as follows:

Check if all prerequisites for the display of data are met. For detailed information, see Prerequisites (Standard MiniALV) or the Prerequisites section in MiniALV (Workplace delivery).

If you get the error message reading "RFC did not return data", you can use the trace mode (service parameter ma_trace auf "on" ) to see at which point no data was transferred and thus determine the cause of the error. Alternatively, you can follow the recommended troubleshooting procedure described in RFC Did not Return Data.

Features

Content

Parameter	Meaning
report	Name of the proxy report
query	Name of a query (as an alternative to the proxy report)
usergroup	For query: user group
workspace	For query: query area
readdatatable ( on \| off )	In the default setting, the system transfers only the output data of the proxy report visible on the screen. To be able to access all data of the output table, set this parameter to on . The hidden data is then transferred in the additional field HiddenData .

Technical Settings

Parameter (Default value)	Meaning
ma_trace (on\| off)	Set this parameter to ' on ' to determine the exact cause of the error "RFC did not return data". See The MiniALV Trace
ma_stateless (on\| off)	In the default setting, the MiniALV keeps a state of the current user session on the ITS. If this parameter is set to "on", the MiniALV becomes stateless and terminates the ITS users session after it is called. MiniALV-specific parameters are resent to the ITS using a hidden form (for example, if another variant is chosen using the shuffler). For all existing and new developments that use the MiniALV, we recommend that you set this parameter to reduce the load on the ITS. The parameter was implemented for compatibility reasons only.

Personalization

Parameter (Default value)	Meaning
variant	Selection variant with which the report is to be started
emptyvariant ( on \| off )	Allows you start the MiniALV with an empty selection variant
layout	Start the MiniALV with an existing layout
seltype (V\|P)	Determines the contents of the combo boxes in the shuffler
userfb	Function module as a user exit to: Customize MiniALV parameters Save settings as user-specific See also: Combo Boxes in the Shuffler

Visual Properties

General

Parameter (Default value)	Meaning
ma_title ( on\|off)	Show/hide title
ma_shuffler (on\| off)	Switch on/off combo box display
ma_Shufflerlayout ( T\|S\|B)	(Text, Simple, Line Break for narrow MiniApps)
ma_style ( scroller\|pages\|text\|graphic\|wap1)	Change the style of the graphical design in the Web browser
ma_sort ( on\|off)	The column heading is displayed as a hyperlink which has been assigned the function for sorting the column. When the column heading is clicked for the first time, the MiniALV sorts the table in ascending order based on this column. When the heading is clicked for the second time, the sorting is in descending order. Whether the column was sorted in ascending or descending order, is indicated by a symbol in the column heading.
ma_color ( on\|off)	The colors defined in the proxy report for rows, columns or individual cells are passed to the MiniALV and displayed there. Set this parameter to 'off' if you want to use the custom colors for the MiniALV. For information on how to color columns, rows and cells, see: Coloring Columns, Rows or Cells (AddOn MiniALV) and Coloring Rows and Coloring Cells (Standard MiniALV).

Lists

(Where ma_style=scroller|pages|text )

Note

The MiniALV uses the column width predefined by the ALV list. See also the description of the field OUTPUTLEN in Output Options of Columns (Standard MiniALV) or Fields of the Field Catalog (AddOn MiniALV).

General

Parameter (Default value)	Meaning
ma_header ( short\|medium\|long\|off )	Determines which text from the Data Dictionary (field label for the data element) is used for the entire MiniALV as the column header
ma_height ( 150 )	Height of the scrollbar table in pixels
ma_lines ( 10 )	Number of rows visible at the same time (only for ma_style=pages )
ma_view ( largeicons\|smallicons\|list\| details )	Type of display

Iconview (where ma_view=largeicons|smallicons|list )

Parameter (Default value)	Meaning
ma_columns ( 10)	Number of columns when icons are displayed
ma_iconspacing ( 2)	Distance between the icons in pixels
ma_iconcolumn ( 1)	Number of the column in the output table that contains icons
ma_textcolumn ( 2)	Number of the column in the output table that contains the text for the icon display
ma_textcolumn ( 0)	Truncates the text for the icon display to the specified number of characters

Portable Interactive Graphics

Portable Interactive Graphics (or PIG) is a service for MiniApps used to embed graphics. The MiniALV includes this service and provides its own parameters for displaying graphics in the list.

As a prerequisite, you must publish the Internet service SPIGITSFL on the ITS for the Standard MiniALV and the Internet service WAOPIG for the AddOn MiniALV.

Note

For more information, see the Portable Interactive Graphics documentation in Graphics in the Workplace.

(Where ma_style=graphic )

Parameter (Default value)	Meaning
ma_view (pie charts, bars, columns, lines, and so on)	Type of graphic corresponds to the parameter type of PIG_TemplateChart .
ma_mode ( java\|igs)	Method used to display the graphic on the frontend Java applets IGS (Internet Graphics Server) For the advantages and disadvantages of this method, see the Portable Interactive Graphics documentation.
ma_width ( 320)	Width of the graphic
ma_height ( 120)	Height of the graphic
ma_textcolumn ( 1)	Number of the column in the output table for the data of the abscissa (X axis)
ma_valuecolumn ( 2)	Number of the column in the output table for the data of the ordinate (Y axis)
ma_colors[]	Array used to determine colors

WAP (Wireless Application Protocol)

(Where ma_style=wap1 (see Output on Small Screens)

Parameter (Default value)	Meaning
maw_columns	You can use this parameter to determine which columns to display and which labels to use for the cells.
maw_sparse	Summarizes the table. Recurring column values are not output again.
