Hi,
just for the record. Here's the code to create a table with 10000 columns, in this example all of type vendor. It could be modified a little to create any dynamic table. Without any visible limits and can be displayed in SALV.
DATA:
    lv_lifnr       TYPE lifnr,
    lv_numc7       TYPE numc7,
    lt_components  TYPE cl_abap_structdescr=>component_table,
    lo_struc_descr TYPE REF TO cl_abap_structdescr,
    lo_tdescr      TYPE REF TO cl_abap_tabledescr,
    lr_tab         TYPE REF TO data.
  FIELD-SYMBOLS:
    <component>   TYPE LINE OF abap_component_tab,
    <range_tab>   TYPE STANDARD TABLE,
    <tab>         TYPE table.
* build dynamic table
  DO 10000 TIMES.
    APPEND INITIAL LINE TO lt_components ASSIGNING <component>.
    <component>-type ?= cl_abap_datadescr=>describe_by_data( lv_lifnr ).
    lv_numc7 = sy-index.
    CONCATENATE 'FIELD' lv_numc7 INTO <component>-name.
  ENDDO.
  lo_struc_descr    ?= cl_abap_structdescr=>create( lt_components ).
  lo_tdescr        = cl_abap_tabledescr=>create( lo_struc_descr ).
  CREATE DATA lr_tab TYPE HANDLE lo_tdescr.
  ASSIGN lr_tab->* TO <tab>.
  APPEND INITIAL LINE TO <tab>.
I discovered that it takes some time (15 seconds or more) to create, even F1 and F4 in the SALV table use considerable time to pop up, I think (SAP never imagined
But it works - and the code is so simple!
Kind regards,
