hello,
thanks for helping me so much....I have asked system administor and the url has been successed run.
but it still errors,there is no 'slug' when I add file and click 'post'.
this is my MPC:
lo_entity_type = model->create_entity_type('File').
lo_entity_type->set_is_media( 'X' ).
lo_property = lo_entity_type->create_property( iv_property_name = 'Mandt'
iv_abap_fieldname = 'MANDT').
lo_property = lo_entity_type->create_property( iv_property_name = 'Filename'
iv_abap_fieldname = 'FILENAME').
lo_property->set_is_key( ).
lo_property = lo_entity_type->create_property( iv_property_name = 'Sydate'
iv_abap_fieldname = 'SYDATE').
lo_property = lo_entity_type->create_property( iv_property_name = 'Sytime'
iv_abap_fieldname = 'SYTIME').
lo_property = lo_entity_type->create_property( iv_property_name = 'Value'
iv_abap_fieldname = 'VALUE').
lo_property = lo_entity_type->create_property( iv_property_name = 'Mimetype'
iv_abap_fieldname = 'MIMETYPE').
lo_entity_type->bind_structure( 'Z_CL_MODEL_PROVIDER=>FILE' ).
lo_entity_type->create_entity_set( 'FILESET' ).
this is my DPC:
method /IWBEP/IF_MGW_APPL_SRV_RUNTIME~CREATE_STREAM.
DATA: ls_key_tab TYPE /iwbep/s_mgw_name_value_pair,
ls_excel TYPE ZEXCELDETAIL.
ls_excel-mimetype = is_media_resource-mime_type.
ls_excel-filename = iv_slug.
ls_excel-value = is_media_resource-value.
copy_data_to_ref( EXPORTING is_data = ls_excel
CHANGING cr_data = er_entity ).
