ALV (ABAP LIST VIEWER).

ALV da soporte a la mayoría de los informes estándares de ABAP R/3. Contiene

una serie de módulos de funciones que podrían ser añadidos a los códigos de los

programas.

También puede añadir aspectos de interfaz a los report. Para incluir ALV en un

report:

1. Declarar data areas.

2. Declarar internal table.

3. Select data into internal table.

4. Build field catalogs.

5. Build event catalogs.

6. start ALV con los módulos.

7. Process call back events.

CREACIÓN DE ESTRUCTURAS1

Abriremos la transacción se11. Escogeremos la opción “DATA TYPE” y le

pondremos nombre. Ahora haremos clic en “create”.

Escogeremos la opción “structure” y continuaremos. Ahora le pondremos una

pequeña descripción a nuestra estructura.

Tras esto comenzaremos a ponerle los campos que deseemos en la columna

“component”. Para darle un formato a ese campo cogeremos campos de los distintos

infotipos, por ejemplo, si cogemos el campo nombre buscaremos un infotipo que

contenga ese campo, comprobaremos el component type(presionando F1 sobre el campo

y clickando en las herramientas) y lo pondremos en la misma fila que nuestro

component. Tras esto guardaremos y la estructura estará creada.

*Para crear una tabla en ABAP a partir de una estructura utilizaremos el siguente trozo

de código:

DATA: tabla TYPE estructura.

1 Transacción SE11.

PROGRAMA ABAP SIN BASES DE DATOS LÓGICAS.

“Recoge datos de diferentes infotipos y los almacena en una tabla interna con formato

de una estructura previamente creada”.

Z_PRUEBAREPORTALV

Para comenzar con ello debemos crear nuestra estructura en la transacción se11 como se

dijo anteriormente.

Ahora crearemos una tabla(i_aux) interna del programa con el formato de la estructura

que creamos anteriormente.

“DATA: i_aux LIKE estructura_nombre

OCCURS 0 WITH HEADER LINE.”

Una vez creada esta tabla crearemos otra para cada infotipo al que recurramos y el 0000,

es decir, si necesitamos los infotipos 0002 y 0006 haríamos 3 tablas, una para cada uno:

“DATA: i_pa0000 LIKE pa0000

OCCURS 0 WITH HEADER LINE.”

…

Recuperamos la información de los infotipos haciendo una consulta y almacenando los

resultados en cada una de las tablas que hemos creado:

“SELECT *

FROM pa0000

INTO TABLE i_pa0000

WHERE2 begda <= sy-datum

3

AND endda >= sy-datum.”

Para las otras tablas:

“SELECT *

FROM pa0002

INTO TABLE i_pa0002

FOR ALL ENTRIES IN i_pa0000

WHERE pernr EQ i_pa0000-pernr

AND begda <= sy-datum

AND endda >= sy-datum.”

“SELECT *

FROM pa0006

INTO TABLE i_pa0006

FOR ALL ENTRIES IN i_pa0000

WHERE pernr EQ i_pa0000-pernr

AND subty EQ c_subty1 4

AND begda <= sy-datum

AND endda >= sy-datum. ”

2 En el WHERE ponemos esta condición para que sólo nos muestre los empleados activos.

3 DATUM es una variable del sistema que almacena la fecha actual.

4 Esta condición hace que se recorra el subtipo 1 del infotipo 6. Para hacerlo menos complejo creo una

constante llamada subty1 con el valor ‘0001’: “CONSTANTS: c_subty1 LIKE pa0006-subty VALUE '1'.”


6

Una vez hecho esto y para comprobar que existen valores utilizamos la variable del

sistema sy-subrc, que siempre que haya valores tendrá 0 como valor, así una vez

recorramos la pa0000 escribiremos la condición:

“IF sy-subrc eq 0.”

Tras esta línea recorreremos nuestras otras dos tablas y pondremos el else como:

“ELSE. MESSAGE a000(z1) WITH text-001.

ENDIF.”

Así habremos terminado la parte de recorrido de infotipos y almacenamiento en tablas

internas. Ahora lo que nos interesa es, de cada tabla, coger los campos que necesitamos,

es decir, los campos que creamos en nuestra estructura.

Para ello haremos un LOOP que recorra toda la p0000 y dos Read Table uno para cada

infotipo de los que recogemos datos. También, para evitar redundancias haremos un

REFRESH sobre nuestra tabla antes del LOOP y un CLEAR cada vez que entre en el

LOOP:

“REFRESH i_aux. LOOP AT i_pa0000. CLEAR i_aux. READ TABLE i_pa0000 WITH KEY pernr = i_pa0000-pernr. IF sy-subrc EQ 0. i_aux-pernr = i_pa0000-pernr. ENDIF. READ TABLE i_pa0002 WITH KEY pernr = i_pa0000-pernr. IF sy-subrc EQ 0. i_aux-name = i_pa0002-vorna. i_aux-lastname = i_pa0002-nachn. i_aux-birth_date = i_pa0002-gbdat. ENDIF. READ TABLE i_pa0006 WITH KEY pernr = i_pa0000-pernr. IF sy-subrc EQ 0. i_aux-street_&_housen = i_pa0006-stras. i_aux-city = i_pa0006-ort01. i_aux-country = i_pa0006-land1. ENDIF. APPEND i_aux.5

ENDLOOP.”

5 Lo almacenamos con APPEND

PROGRAMA ABAP CON BASES DE DATOS LÓGICAS.

“Recoge datos de diferentes infotipos y los almacena en una tabla interna con formato

de una estructura previamente creada”.

Z_PRUEBAREPORTALV2

Para empezar hemos creado una estructura que contiene campos de diferentes

infotipos(z_structuratest). En primer lugar insertamos las tablas a las que hacemos

acceso:

“TABLES:pernr.”

Luego los infotipos:

“INFOTYPES:0000,0001,0002,0006,0009.”

Ahora declaramos la tabla interna en la que almacenaremos los datos:

“DATA: i_aux LIKE zstructuretest OCCURS 0 WITH HEADER LINE.”

A continuación recogeremos el pernr y haremos mención a la función de inserción:

“INITIALIZATION. START-OF-SELECTION. GET pernr. PERFORM lectura_inserccion.

END-OF-SELECTION.”

Ahora picaremos nuestra function:

“FORM lectura_inserccion .”

Tenemos dos opciones utilizando provide o loop, con provide sería:

“provide * from p0000 between pnpbegda and pnpendda. *CODIGO*

endprovide.”

Utilizando loop sería:

“LOOP AT p0000 WHERE begda >= pnpbegda AND endda <= pnpendda. *CODIGO*

ENDLOOP.”

Siendo el código:

“ i_aux-personal_number = p0001-pernr. i_aux-company_code = p0001-bukrs. i_aux-personal_area = p0001-werks. i_aux-employee_group = p0001-persg. i_aux-employee_subgroup = p0001-persk. i_aux-organizational_key = p0001-vdsk1. i_aux-payroll_area = p0001-abkrs. i_aux-first_name = p0002-vorna. i_aux-last_name = p0002-nachn. i_aux-street_&_housen = p0006-stras. i_aux-city = p0006-ort01. i_aux-country = p0006-land1. i_aux-bank_key = p0009-bankl. i_aux-bank_account = p0009-bankn. i_aux-payroll_area = p0009-bkont.

APPEND i_aux.”
