Hola tengo este batch input:

report ZDAGO_VL02
no standard page heading line-size 255.

include bdcrecx1.

parameters: dataset(132) lower case.
*** DO NOT CHANGE - the generated data section - DO NOT CHANGE ***

* If it is nessesary to change the data section use the rules:
* 1.) Each definition of a field exists of two lines
* 2.) The first line shows exactly the comment
* '* data element: ' followed with the data element
* which describes the field.
* If you don't have a data element use the
* comment without a data element name
* 3.) The second line shows the fieldname of the
* structure, the fieldname must consist of
* a fieldname and optional the character '_' and
* three numbers and the field length in brackets
* 4.) Each field must be type C.

Debo hacer un programa que mediante 2 parametros:
p_guia like likp-vbeln.
p_bultos like likp-anzpk.

modifique esos valores usando esa transaccion antrior de batch input, que hice cree un nuevo programa agregue esos parámetros y copie ese mismo programa, no se si ma falta algo mas porque no me ejecuta bien, alguien me podria ayudar por favor?...
