Hi

Thnaku for the reply.

I have a structure (fixed), by using this structure i want to create multiple internal tabnles with the same structure. For example i have a data in an internal table which has n company codes. So i need to take n company codes data into n internal tables. like itab1, itab2, itab3,........ itabn with the same structure. And also i need to assign these internal table as a patrameters to the funtion module REUSE_ALV_BLOCKLIST_APPEND.

I hope u undestand my requirment. Kindly help me in this.

Hi Kaduri, <li>By the way, You can call REUSE_ALV_BLOCKLIST_APPEND only 19 times in any report. If it goes beyond, It gives dump. Thanks Venkat.O

Hi,

For creating dynamic internal table we need to use class

CL_ALV_TABLE_CREATE

Basic principal would be, we need to fill the field catalog table and pass it to static method CREATE_DYNAMIC_TABLE from class

CL_ALV_TABLE_CREATE.

CALL METHOD cl_alv_table_create=>create_dynamic_table

 CALL METHOD cl_alv_table_create=>create_dynamic_table 
    EXPORTING 
      it_fieldcatalog = t_fldcat                   
    IMPORTING 
      ep_table        = t_newtable.        

    

Thanks,

first you can create reference work area and filed symbols(dynamic internal table) like below

data : ref_area type ref to data .

filed-symbols : <fs_itab> type standard table .

after user reference work area to create data that include fixed structure data attribute .

create data ref_area like standard table of str_fixdata（u2192this is you fixed structure )

finally assign field symbols to reference area

assign ref_area->* to <fs_itab> .

the <fs_itab> is dynamic internal table that attribute likes you defined fix structure .
