Dynamic ALV Grid

Former Member — Fri, 03 Sep 2010 14:35:22 GMT

Dear expert,

my requirement is to create a custom program with dynamic ALV grid output. The fields cointaned into output header have to follow the selection parameter characteristics.

e.g.

INPUT = material X (material X has CLASS A with 6 characteristics)

OUTPUT = header with 6 fields

INPUT = material Y (material Y has CLASS B with 9 characteristics)

OUTPUT = header with 9 fields

INPUT = material X and Y (material X has CLASS A with 6 characteristics +material Y has CLASS B with 9 characteristics)

OUTPUT = header with 15 fields

Any help will be appreciated.

Thank you in advance,

Fuffo

Just a rough code



TYPES:BEGIN OF ty,
matnr TYPE matnr,
END OF ty.

DATA:i_sclass TYPE TABLE OF sclass,
     i_object TYPE TABLE OF clobjdat,
     la_object TYPE  clobjdat,
     li_index(2) TYPE n,
     lines TYPE i.

DATA:i_tot_comp TYPE cl_abap_structdescr=>component_table,
     lf_struct TYPE REF TO cl_abap_structdescr,
     lf_element TYPE REF TO cl_abap_elemdescr,
     la_comp LIKE LINE OF i_tot_comp,

     lf_new_type TYPE REF TO cl_abap_structdescr,
     lf_new_tab TYPE REF TO cl_abap_tabledescr.

You have use the logic above and build your program.

Thank You for your reply Keshav,

I forgot to say that we are working on R/3 4.7 so I can't use the logic you propose.

Any other help?

Thank you in advance,
