Any idea how to achieve this?

Hi Vemulapalli,

Are you doing MASS update of Materials ? Even during MASS update, DERIVE ENTITY will be triggered. Check BADI's USMD_RULE_SERVICE, USMD_RULE_SERVICE_CROSS_ET

Hi MDG user,

In derive_entity method for  BADi USMD_RULE_SERVICE.

CALL METHOD io_model->read_entity_data_all

         EXPORTING

           i_fieldname      = 'MATERIAL'

           if_active        = abap_false

           i_crequest       = lv_crequest

*         it_sel           =

           it_entity_filter = lt_filter

         IMPORTING

*         et_message       =

           et_data_entity   = e_data.

with the above code able to read the materials attached to change request but i need to read only selected material for derive_entity method.

Hi Vemulapalli,

Did you try IO_CHANGED_DATA parameter in cross BADI  USMD_RULE_SERVICE_CROSS_ET ?

Hi MDG user,

It retrieves material number only when changes are done in MATERIAL entity, need to retrieve material number when changes are done in  other entities also.

Is there any method to achieve this?

Hi Vemulapalli,

In general you would always get the Material number in case of change happens in other entities also.

EX:

DATA: lr_mod          TYPE REF TO data.

FIELD-SYMBOLS: <lt_mod>         TYPE SORTED TABLE.

FIELD-SYMBOLS: <ls_mod>         TYPE any.

FIELD-SYMBOLS: <lv_matnr>       TYPE matnr.

DATA: lt_matnr        TYPE SORTED TABLE OF matnr WITH UNIQUE KEY table_line.

   CALL METHOD io_changed_data->read_data
     EXPORTING
       i_entity      = if_mdg_bs_mat_gen_c=>gc_entity_valuation
     IMPORTING
       er_t_data_mod = lr_mod.
   CHECK lr_mod IS BOUND.
   ASSIGN lr_mod->* TO <lt_mod>.
   CHECK sy-subrc = 0 AND <lt_mod> IS ASSIGNED AND <lt_mod> IS NOT INITIAL.
   " Get the material numbers
   LOOP AT <lt_mod> ASSIGNING <ls_mod>.
     ASSIGN COMPONENT if_mdg_bs_mat_gen_c=>gc_attr_material OF STRUCTURE <ls_mod> TO <lv_matnr>.
     INSERT <lv_matnr> INTO TABLE lt_matnr.
   ENDLOOP.
