You have to create the fieldcatalog for the REUSE FM.

Check the link -

u have to maintain field catalog or u have to pass ref structure name for this FM.

check i_structure parameter.

well you are giving an empty field cat to the ALV.

HJe doesnt like that. either build your field cat before sending it to the FM, or forget about that fieldcat and use the parameter I_STRUCTURE of the FM.

give the structure of your data to that parameter ( the structure of the table your data is beeing stored in).

u had not maintained the field catalog for it,

just check the sample programs in package SLIS.
