Field Catalog from data object..

former_member261876 — Tue, 09 Nov 2010 16:33:25 GMT

Hi all,

data:

g_head_ref TYPE REF TO data,

g_item_ref TYPE REF TO data.

CALL BADI handle->set_header_item_data

EXPORTING

i_document_type = g_document_type

i_head_item = g_head_item

i_ab_document_type = doc_typ

i_header_table = g_header_table

i_item_table = g_item_table

i_map_fields = g_map_fields

IMPORTING

e_subrc = l_subrc

e_head_ref = g_head_ref

e_item_ref = g_item_ref.

here i get the g_data_ref and g_item_ref filled with the values..

now i assigned these object to field symbols to display the same in the ALV.....

Issues is follwoing-->

I dont know the table structure or table name with which these ref object or the field symbols is type of now....

(in this case it can be a local prog type defined structure..)..

how can i create a fieldcatlog out of it..??

I have already tried

FM 'REUSE_ALV_FIELDCATALOG_MERGE' --> need an internal table with defined type...

cl_abap_structdescr=>describe_by_data --> need a DDIC structure (in this case it can be a local prog type defined structure..)..

if the class cl_abap_structdescr is the correct way to do it...please let me know exact flow of methods...if there is some other solution do let me know.

Regards,

Yadesh

i don't know what the variable g_map_fields, perhaps has it the definition of the table? if it's so you can use it to fill catalog table for ALV, else you can use CL_ABAP_STRUCTDESCR

 data: g_head_ref TYPE REF TO data.
data: g_item_ref TYPE REF TO data.


..............................................................

field-symbols: <fs_head> type table.
field-symbols: <fs_wa> type any.

data: l_comp type flag.

DATA: MY_STRUCT TYPE REF TO CL_ABAP_STRUCTDESCR.

ASSIGN g_head_ref->* TO <fs_head>.

LOOP AT <fs_head> ASSIGNING <fs_wa>.
    MY_STRUCT ?= CL_ABAP_TYPEDESCR=>DESCRIBE_BY_DATA( <fs_wa> ).
    EXIT.
ENDLOOP.

Now in MY_STRUCT->COMPONENTS you have the definition of the table and u can use it in order to fill the catalog table for ALV

Hi....

*Issues is follwoing-->

*(in this case it can be a local prog type defined structure..)..

Sorry but you should have any "names" at runtime, in debug mode...

In that case we've to use field-symbol approach... Try to give any debug information... tables name, field name, etc.. of your interest
