How to get the latest text value? (MDG BAdI USMD_RULE_SERVICE_CROSS_ET)

[queue]

Dear experts,

Can you please help me with the logic to get the latest value which the user input to text(lang+text) fields?

I am using
BAdI USMD_RULE_SERVICE_CROSS_ET
Method IF_EX_USMD_RULE_SERVICE2~DERIVE.

Code:

CALL METHOD io_model->create_data_reference
EXPORTING
i_fieldname = if_mdg_bs_mat_gen_c=>gc_fieldname_material
i_struct = if_usmd_gov_api_entity=>gc_struct_key_txt_langu
i_tabtype = if_usmd_model_ext=>gc_tabtype_standard
IMPORTING
er_data = lrt_desc_data.

ASSIGN lrt_desc_data->* TO <lt_description>.

CREATE DATA lrs_desc LIKE LINE OF <lt_description>.

IF lrs_desc IS INITIAL.
RETURN.
ENDIF.

ASSIGN lrs_desc->* TO FIELD-SYMBOL(<ls_description>).

io_model->read_char_value(
EXPORTING
i_fieldname = if_mdg_bs_mat_gen_c=>gc_fieldname_material
it_sel = lt_sel
if_no_flush = abap_false

IMPORTING
et_data = <lt_description>
et_message = lt_message ).

As a result, I could get the value which is "BEFORE the latest input".

For example, when a user change text from "AA" to "ABC", I could get "AA" as a text value in stead of "ABC".
Could you please advise me how to get the latest text values?

Thank you
Yuko

Hi,

you have the values in the parameter IO_CHANGED_DATA of the method, you are trying to read them from IO_MODEL and there the values are passed after the BAdI is triggered.

In this BAdI if you need "fresh data", first read it from IO_CHANGED_DATA and if it is not there (means it was not changed since last flush) then get it from IO_MODEL

Hi pstudenc,

I really appreciate your prompt answer.
I changed source code as follows;

io_changed_data->read_data(
Exporting
i_entity = if_mdg_bs_mat_gen_c=>gc_entity_material
i_struct = if_usmd_gov_api_entity=>gc_struct_key_txt_langu
Importing
er_t_data_mod = lrt_description).

Then it works as I expected!!

Thank you 🙂
