ALV para cualquier it

[fcorodriguezl]

Hola chavos,

Encontre en internet un programita para desplegar en un alv cualquier tabla interna. Hice una primera prueba con un prog. sencillo y funciono. No asi cuando lo incluyo en mi programa.

El error que devuelve es:
Lt_abap is not type -compatible with formal parameter "ABAP"

La declaracion viene asi:

DATA: lt_abap TYPE TABLE OF rssource.

Estoy buscando a que se refiere en rssource, pero sin exito aun.
Si alguien puede darme una idea lo agradezco como siempre.

Gracias.

Rsource es una estructura . te la copio debajo:
Structure :RSSOURCE
Short text :Program source
Component Comp type DTyp Length Dec. sshort text
LINE EDPLINE CHAR 72 0 EDIC:Prog editor line

No me queda claro lo del error que te muestra. Copia aquí el programa a ver que podemos ver

este es el codigo del prog. En rojo pongo donde me da el error.

No puedo ayudarte pues no me da ningún error....
Además esa declaración está en zona privada, no debieras llamar ni explotar ese método. Lo hace sólo el código. Todo lo que hay que escribir en tu programa es el include a todo ese código y :
CALL METHOD lcl_table_display=>display_list ( or display_grid )
EXPORTING data = yourinternaltable
Y de esa manera a mi me resultó bien. ... ¿no habrás alterado algo al armar tu include??
