A Visual Explanation of SQL Joins

Subroutines

Sintaxis de declaración: (igual para subrutinas internas y externas) FORM nombre [ parámetros ]. statements. ENDFORM.

Llamada a una subrutina interna: PERFORM nombre [ parámetros ]. Llamada a una subrutina externa: PERFORM name (programa) [ paráms ] [ IF FOUND ]. En este caso se debe indicar el programa en el cual se encuentra la subrutina llamada. Con IF FOUND, si la subrutina no existe, la sentencia PERFORM es ignorada y no se genera error.

CALL BY REFERENCEEl parámetro formal y el actual ocupan la misma posición de memoria, con lo que su valor puede ser modificado por la subrutina. Se pasa la dirección del parámetro, no una copia. Se puede usar en TABLES, USING y CHANGING.

FORM nombre [ parámetros ]. USING Value(pv_act) TYPE I Value(pv_max) TYPE I CHANGING Value(cv_pc) TYPE gty_perc.

Working with Structures

[ Defining Structures with Local Types ]

TYPES: BEGIN OF st_flightinfo, carrid TYPE s_carr_id, connid TYPE s_conn_id, fldate TYPE s_date, END OF wa_flightinfo TYPE st_flightinfo.

DATA wa_flightinfo TYPE st_flightinfo.

[ Access to Structure Components ]structure_name-component_name.

DATA: wa_scarr TYPE scarr.

wa_scarr-carrid = ‘LH’.

SELECT SINGLE * FROM scarr INTO wa_scarr WHERE carrid = wa_scarr-carrid.

WRITE:/ wa_scarr-carrid, wa_scarr-carrname, wa_scarr-url.

[ Copying Structure Components with the Same Name ]

DATA: wa-sflight TYPE sflight, wa_focc TYPE sbc400focc. MOVE-CORRESPONDING wa_sflight TO wa_focc.

ScreensThe screens in a single ABAP program can be combined to form screen sequences. You can call single screens or screen sequences either using a transaction code from outside the ABAP program, or by using the CALL SCREEN statement in the corresponding ABAP program. When you call a screen or screen sequence, the screen flow logic takes control of the ABAP program execution. You can define screen sequences dynamically by setting the next screen attribute for a screen dynamically in the ABAP program.

CONTROLS ctrl TYPE TABLEVIEW USING SCREEN scr.

Selection screens are one of the three types of screen in the R/3 System, along with dialog screens and lists. You use them whenever you want the user to enter either a single value for a field or fields, or to enter selection criteria.Las listas no definen botones y recursos con nombres que luego se utilizan en ABAP en este caso se utilizan areas de trabajo libres y las sentencias WRITE, ULINE; and SKIP .

[ SELECT SCREEN ]Tres sentencias para manejar las select screen.

• PARAMETERS for single fields• SELECT-OPTIONS for complex selections• SELECTION-SCREEN for formatting the selection screen and

defining user-specific selection screensSELECTION-SCREEN BEGIN OF SCREEN <numb><title>] [AS WINDOW].</title> [TITLE
