Making into single table

Question

Hi,
I have two file path at selection screen where I upload one field names file and one record file for the fields uploaded.
I have an internal table with fields id, pid, structure_name, pk_field(parent key), fk_field(foreign key),fields(table type-the file field names that uploaded in my selection screen),data(this is also a table and has the record file that I have uploaded at selection screen).My internal table looks as follows:
ID     PID     structure_name     pk_field     fk_field     fields     data
1          header     abcd          t_fields1     t_rec1
2     1     item     gfh     abcd     t_fields2     t_rec2
Now my requirement is to flatten the data into single table with the following fields based on the parent key(pk) and foreign key(fk) relation.Can anyone suggest how to do it.
structure_name
field_name
pk
fk
value

Answer 1

One more thing which I don't get. Does DYN_TABLE holds values 1,2,3 as 3 records?
1) value 1
2) value 2
3) value 3
or
this is just one record with different fields, but you only want to copy those F1, F2, F3 fields for which values are like 1, 2, 3, to new table?
I think you mean the second, so this would be what you need
data: it_fcat type lvc_f_cat with header line.
"first creat field catalog based on fields names
loop at fields.
    it_fcat-fieldname = fields-name.
    "give field type, either excplicitly or via DDIC reference
    it_fcat-INTTYPE = ...
    it_fcat-INTLEN = ...
    append it_fcat.
endloop.
now create new dynamic table
field-symbols <new_tab> type any table.
data: new_table type ref to data.
    CALL METHOD cl_alv_table_create=>create_dynamic_table
      EXPORTING
        it_fieldcatalog = is_fcat
      IMPORTING
        ep_table        = new_table.
assign new_table->* to <new_tab>.
Last thing you need is to move values from DYN_TAB to corresponding NEW_TAB
data: wa_dyn_tab type ref to data,
          wa_new_tab type ref to data.
field-symbols <dyn_tab> type any table,
                         <wa_dyn> type any,
                         <wa_new> type any.
assign dyn_tab->* to <dyn_tab>.
"create work areas for both tables
create data: wa_dyn_tab like line of <tab>,
                      wa_new_tab like line of <new_tab>.
assign: wa_dyn_tab->* to <wa_dyn>,
               wa_new_tab->* to <wa_new>.     
"now copy content from DYN_TAB to NEW_TAB using <wa_dyn> and <wa_new>.
loop at <dyn_tab> into <wa_dyn>.
   move-corresponding <wa_dyn> to <wa_new>. 
   append <wa_new> to <new_tab>.   "now <new_tab> contains only corresponding values from <dyn_tab> based on FIELDS table
endloop.
Hope this is what you need
Regards
