SAP ABAP report programming-08

SAP ABAP Report programming -08

SAP-ABAP Two types of programs are supported - Reporting procedures and dialogue procedures . report form The program uses... When it needs to display a large amount of data

In this tutorial , You will learn ：

• Select screen
• ABAP Report planned events
• Format report
• Interactive report programming
• Logical database

The purpose of the reporting procedure / purpose

• When data from multiple tables must be selected and processed before rendering , They will be used
• Use... When a report requires a special format
• When the report must be transferred from SAP Download to the to be distributed Excel Use... When working with worksheets .
• Use when the report must be mailed to a specific person .

Notes on reporting procedures

• The reporter is always an executable program . The program type is always 1.
• Each reporter corresponds to a specific application type , Sales and distribution ,FI - CO etc. . It can also be cross application , That is, type “*”.
• Report programming is an event driven programming .
• The first line of the reporter is always the report *< Report name >.*
• To suppress the display of list titles or program names , Please use add *“ No standard page title *”.
• You can use the addition line size < size > To set up a specific report Line size of .
• You can use the addition line count n（n1） To set the row count for a particular page .N Is the number of lines on the page ,N1 Is the number of rows reserved for the page footer .
• To display any information or error messages , We use the added add Add a message class to the program in ：Message-id<message Class name >. The mail class is in SE91 In the maintenance .

therefore , The ideal reporting process should begin with ：

Report <report name> no standard page heading

line-size <size>

line-count <n(n1)>

message-id <message class>.

Select screen

Select screen ” Is a screen that specifies the input values that the program should run .

The selection screen usually starts from

1. Parameters
2. choice - Options

grammar

Selection-screen begin of screen <screen #>
selection-screen begin of block <#>  with frame title <text>
.........
.........
selection-screen end of block <#>
selection-screen end of screen <screen #>

Parameters

Parameters help with dynamic selection . They can only hold one value for one execution cycle of the program .

grammar

Define parameters as data types

Parameters p_id(30) type c.

Defining parameters , As shown in the table .

Parameter p_id like <table name>-<field name>.

The parameter can be a check box , It can also be a radio button .

Parameters p_id as checkbox.Parameters p_id1 radiobutton group <group name>.
Parameters p_id2  radiobutton group <group name>.

The parameter can be a list box .

Parameter p_id like <table name>-<field name> as listbox

Select options

The selection option is used to enter a series of values or a set of values into the program

grammar

select-options s_vbeln for vbak-vbeln.

You can also define a selection option , Such as variable

select-options s_vbeln for vbak-vbeln no intervals no-extension

ABAP Report planned events

ABAP The reporting procedure is Event driven programs . Different events in the report Program Include ：

Program loading

• The load type is 1、M、F or S After , Trigger the associated event in the internal session .
• Run the associated processing block once for each program and internal session at the same time , And only run once .
• For types of 1、M、F or S Of ABAP Program , Processing block LOAD-OF-PROGRAM Functions and constructors of for ABAP Classes in the object have roughly the same functions

initialization .

• This event is executed before the selection screen is displayed .
• Initialize all values .
• You can specify values other than the default values on the selection screen .
• You can fill the selection screen with some values at run time .

On the selection screen .

• When processing the selection screen （ stay PAI At the end of ） Deal with the incident .
• The validation and check of input values are performed here

Start choosing .

• ad locum , The program starts selecting values from the table .

Choose the end .

• After selecting all data , This event writes data to the screen .

Interactive activities

• For interactive reporting . It is used to create detailed lists from basic lists .

Format report

ABAP It is allowed to set the format of the report to the format desired by the user . for example ,“ Alternate row ” Must be displayed in different colors ,“ A total of ” Lines should be displayed in yellow .

grammar

Format Color n

Format Color n Intensified On

n It can correspond to various numbers

Please note that , Besides the format , There are other additions

FORMAT COLOR OFF INTENSIFIED OFF INVERSE OFF HOTSPOT OFF INPUT OFF

Interactive report programming

• Use interactive programming , Users can actively control the retrieval and display of data
• Used to create detailed lists from very basic lists
• The detailed data is written in the auxiliary list .
• The auxiliary list can completely cover the first screen , It can also be displayed in a new screen
• The auxiliary list itself can be interactive .
• The first list can also invoke transactions .
• There are different events associated with interactive programming .

Some commands for interactive programming

hotspot

If you drag the mouse over the data displayed in the report , The cursor changes to “ Hold out your index finger ” hand . have access to FORMAT Statement implementation hotspot .

Syntax:      Format Hotspot On (Off).

hide

This command helps you store field names based on field names that will be processed further , For a detailed list . It is written directly in the field WRITE After statement . When selecting rows , Values are automatically populated into variables for further use .

Syntax:     Hide <field-name>.

Logical database

• You can use a logical database to retrieve program data , Instead of using “ choice ” Inquire about .
• The logical database consists of transactions SE36 establish
• The name of a logical database can contain at most 20 Characters . It may start with a namespace prefix .
• The data is selected by another program , have access to GET Command access data , This command places the data in the workspace .

Logical database is relative to common database Select Advantages of query .

1. It provides inspection conditions , To see if the input is correct , Complete and reasonable
2. It contains a central authorization check for database access
3. Performance improvements and other enhancements are immediately applied to all reports that use a logical database .

notes ： Due to the complexity involved , In most cases, logical databases are not used
