Adapt data to transfer


The following site will assist you how to adapt the data of a material which is transferred to Product Classification.

Let us start with adapting the alternative material number. The standard just fill the alternative material number with the external represenation of the SAP material no.
The first thing you have to know: Some of our fields with simple data types like char or string are implemented as so called nullable values. So we have a class representation of each simple data type.
If you change such a field you need to use the correct type. For the material number you have to use the class /AEB/CL_01_CHAR_50_NV. NV means nullable values. To create this nullable value, the BAdI method offers you the parameter im_nullable_value_factory. Each nullable value has the attribte v for value.
Why do we use nullable values? To differentiate between whether or not an empty value will lead to an update in Product Classification. In case of a wanted update you have to create the nullable value without assign a value to v. If there should be no update, set the alternative material number in the interface to "NULL".

    matnr_nv  TYPE REF TO /aeb/cl_01_char_50_nv,
    matnr     TYPE matnr,
    alt_matnr TYPE REF TO /aeb/cl_01_char_50_nv.

  matnr_nv = im_value->get_material_no( ).
  matnr = matnr_nv->v.
  IF matnr = 'M-11'.
    alt_matnr = im_nullable_value_factory->char_50( 'M-11-TEST' ).
    im_value->set_alt_material_no( alt_matnr ).  

Okay, know to a more complex case. You like to adapt the value of a classification. In the following example we will change the value of COCO_IMPORT (commodity code for import 10/11 digits) for the classification for 'DE' to a hard coded value.
First you have to loop over the classifications. Then you have to check if the country_iso is 'DE'. And then you have to check it the value is the COCO_IMPORT. In this case we change it to a fixed value of '01022959310'.

    classifications TYPE /aeb/if_ta_pb_ft_mcls20_do=>tt_ft_mcls20_do,
    current_cls     TYPE REF TO /aeb/if_ta_pb_ft_mcls20_do,
    country_iso_nv  TYPE REF TO /aeb/cl_01_char_2_nv,
    values          TYPE /aeb/if_ta_pb_mat_cls_val_do=>tt_mat_cls_val_do,
    current_value   TYPE REF TO /aeb/if_ta_pb_mat_cls_val_do,
    identcode_nv    TYPE REF TO /aeb/cl_01_char_20_nv,
    value_nv        TYPE REF TO /aeb/cl_01_string_nv.
   classifications = im_value->get_classifications( ).
    LOOP AT classifications INTO current_cls.
      country_iso_nv = current_cls->get_countryisocode( ).
      IF country_iso_nv->v = 'DE'.
        values = current_cls->get_values( ).
        LOOP AT values INTO current_value.
          identcode_nv = current_value->get_identcode( ).
          IF identcode_nv->v = 'COCO_IMPORT'.
            value_nv = im_nullable_value_factory->string( '01022959310' ).
            current_value->set_value( value_nv ).

As you see the whole material is implemented object-oriented. So in order to access the classifications you have to call the method get_classifications.
How to add a classification? See the example below.

    identcode_nv        TYPE REF TO /aeb/cl_01_char_50_nv,
    value_nv            TYPE REF TO /aeb/cl_01_char_255_nv,
    classification_code TYPE REF TO /aeb/if_ta_pb_mat_cls_code_do.

  identcode_nv = im_nullable_value_factory->char_50( 'ID_123' ).
  value_nv = im_nullable_value_factory->char_255( 'VALUE_123' ).
  classification_code = im_data_object_factory->new_ta_pb_mat_cls_code_do(
                                                  im_identcode = identcode_nv
                                                  im_value     = value_nv ).

  classification_code->set_approved( im_nullable_value_factory->boolean( 'X' ) ). "optional, add if you want to release the classification value
  classification_code->set_iso_code( im_nullable_value_factory->char2( 'DE' ) ).  "optional, add if the classification is country dependent 

  im_value->add_classification_code( classification_code ).

Ok let us try another thing. If you like to add a certificate to a classification you have to select the classification you like to add the certificate to and then call the method add_certificate. To create a certificate you have to use the parameter im_data_object_factory which is provided by the BAdI method.

    certificate    TYPE REF TO /aeb/if_ta_pb_ft_cert_do,
    add_expl       TYPE REF TO /aeb/cl_01_char_35_nv,
    reference      TYPE REF TO /aeb/cl_01_char_35_nv,
    detail         TYPE REF TO /aeb/cl_01_char_12_nv,
    geo_id         TYPE REF TO /aeb/cl_01_char_10_nv,
    type_code      TYPE REF TO /aeb/cl_01_char_5_nv,
    type_qualifier TYPE REF TO /aeb/cl_01_char_3_nv,
    date           TYPE REF TO /aeb/cl_01_dats_nv,
    cls_dos        TYPE /aeb/if_ta_pb_ft_mcls20_do=>tt_ft_mcls20_do,
    cls_do         TYPE REF TO /aeb/if_ta_pb_ft_mcls20_do,
    country_iso_nv TYPE REF TO /aeb/cl_01_char_2_nv.

  add_expl = im_nullable_value_factory->char_35( 'To be filled' ).
  reference = im_nullable_value_factory->char_35( '1235434' ).
  detail = im_nullable_value_factory->char_12( 'The detail' ).
  geo_id = im_nullable_value_factory->char_10( 'US' ).
  type_code = im_nullable_value_factory->char_5( 'Y921' ).
  type_qualifier = im_nullable_value_factory->char_3( 'ZW' ).
  date = im_nullable_value_factory->dats( '20190101' ).

  certificate = im_data_object_factory->new_ta_pb_ft_cert_do(
                          im_cert_additional_expl = add_expl
                          im_cert_date_of_issue = date
                          im_cert_detail = detail
                          im_cert_reference = reference
                          im_geo_id = geo_id
                          im_type_code = type_code
                          im_type_qualifier = type_qualifier
                          im_valid_from = date).

  cls_dos = im_value->get_classifications( ).
  LOOP AT cls_dos INTO cls_do.
    country_iso_nv = cls_do->get_countryisocode( ).
    IF country_iso_nv->v = 'DE'.
      cls_do->add_certificate( certificate ).

And here another example which shows how to add attachments to your material.
Please note that this example uses fronted service. This won't work in productiv implementation, but for testing it will work.

    attachment      TYPE REF TO /aeb/if_ta_pb_mat_att_do,
    file_name_nv    TYPE REF TO /aeb/cl_01_char_250_nv,
    attachment_data TYPE /aeb/01_rawstring,
    description_nv  TYPE REF TO /aeb/cl_01_string_nv,
    encoding_nv     TYPE REF TO /aeb/cl_01_char_50_nv,
    property        TYPE REF TO /aeb/if_ta_pb_mat_prop_do,
    mime_type_nv    TYPE REF TO /aeb/cl_01_char_50_nv,
    lt_file_table   TYPE filetable,
    lv_file         TYPE string,
    lv_rc           TYPE i,
    file_manager    TYPE REF TO cl_file_system_manager,
    string          TYPE string,
    lt_rawtab       TYPE TABLE OF char255.

  CALL METHOD cl_gui_frontend_services=>file_open_dialog
      window_title      = 'Select file'
      file_filter       = ''
      initial_directory = ''
      multiselection    = ''
      file_table        = lt_file_table
      rc                = lv_rc.
  READ TABLE lt_file_table INTO lv_file INDEX 1.
  CALL METHOD cl_gui_frontend_services=>gui_upload
    filename = lv_file
    data_tab = lt_rawtab.
  READ TABLE lt_rawtab INTO string INDEX 1.
      text   = string
      buffer = attachment_data.

  file_name_nv = im_nullable_value_factory->char_250( 'Testfile' ).
  description_nv = im_nullable_value_factory->string( 'This is just a test' ).
  encoding_nv = im_nullable_value_factory->char_50( 'UFT-8' ).
  mime_type_nv = im_nullable_value_factory->char_50( 'text/plain' ).

  attachment = im_data_object_factory->new_ta_pb_mat_att_do( 
  im_file_name              = file_name_nv
  im_attachment_data        = attachment_data
  im_attachment_description = description_nv
  im_encoding               = encoding_nv
  im_mime_type              = mime_type_nv ).
  im_value->add_attachment( attachment ).
      attachment      TYPE REF TO /aeb/if_ta_pb_mat_att_do,
      file_name_nv    TYPE REF TO /aeb/cl_01_char_250_nv,
      attach_descr_nv TYPE REF TO /aeb/cl_01_string_nv,
      attachment_data TYPE /aeb/01_rawstring. " Just a dummy..

    " The file Name is the Link
    file_name_nv = im_nullable_value_factory->char_250( '' ).
    attach_descr_nv = im_nullable_value_factory->string( 'Description of the attachment' ).

    attachment = im_data_object_factory->new_ta_pb_mat_att_do(
      im_file_name              = file_name_nv
      im_attachment_data        = attachment_data
      im_attachment_description = attach_descr_nv ).

    im_value->add_attachment( attachment ).

If you like to have context data for example of the material (MARA, MARC..) or if you like to have the relevant org. units use the parameter "IM_MATERIAL_CONTEXT". This parameter has some methods for example get_mara with which you can the actual content of the table mara (include the content which is not yet persistent).
To add additional goods properties to your material you have to use method add_property.

lv_id = 'PROPERTY_ID'.
lv_value = 'PROPERTY_VALUE'.

lo_property = im_data_object_factory->new_ta_pb_mat_prop_do( im_identcode = lv_id
                                                             im_value     = lv_value ).
im_value->add_property( im_value = lo_property ).
