SAP訂單上Shipping抬頭和行專案欄位的持久化實現原理
It is known that we can maintain shipping data for order header and order item separately.
For example, suppose when I have maintained the following data, what happens when save button is clicked?
First all links to this service order is retrieved by function module CRM_GET_ALL_LINKS which works based on database table CRMD_LINK.
The link data has the following format:
The persistence of shipping data is done in function module CRM_SHIPPING_SAVE_OB:
The header guid together with all link data is put into the generic function module CRM_ORDER_UPDATE_TABLES_DETERM, which will calculate current change mode ( insert, update or delete ) by comparing object buffer with database buffer.
In this example, the determined change are two update operations as expected.
Now let’s write a standalone report to perform the change on both header and item shipping data and try to interpret these two changes by our own code.
REPORT crms4_change_shipping. PARAMETERS: inh TYPE crmd_shipping-incoterms2 OBLIGATORY DEFAULT 'header', ini LIKE inh OBLIGATORY DEFAULT 'item', srvo_id TYPE crmd_orderadm_h-object_id OBLIGATORY DEFAULT '8000000111'. DATA: lv_srvo_guid TYPE crmd_orderadm_h-guid, lt_changed_fields TYPE crmt_input_field_tab, ls_changed_fields LIKE LINE OF lt_changed_fields, lt_orderadm_i TYPE TABLE OF crmd_orderadm_i, lt_shipping TYPE crmt_shipping_comt, ls_shipping LIKE LINE OF lt_shipping. START-OF-SELECTION. SELECT SINGLE * INTO @DATA(ls_header) FROM crmd_orderadm_h WHERE object_id = @srvo_id. IF sy-subrc <> 0. WRITE:/ 'Service order not found for id:', srvo_id. RETURN. ENDIF. lv_srvo_guid = ls_header-guid. SELECT SINGLE guid INTO @DATA(lv_item_guid) FROM crmd_orderadm_i WHERE header = @lv_srvo_guid. IF sy-subrc <> 0. WRITE:/ 'No item found for service order:', srvo_id. RETURN. ENDIF. SELECT * INTO TABLE @DATA(lt_link) FROM crmd_link WHERE ( guid_hi = @lv_srvo_guid OR guid_hi = @lv_item_guid ) AND objtype_set = '12'. SELECT * INTO TABLE @DATA(lt_shipping_db) FROM crmd_shipping FOR ALL ENTRIES IN @lt_link WHERE guid = @lt_link-guid_set. IF lines( lt_shipping_db ) <> 2. WRITE:/ 'corrupted shipping data'. RETURN.

MOVE-CORRESPONDING <item> TO ls_shipping. ls_shipping-ref_guid = lv_item_guid. ls_shipping-ref_kind = 'B'. INSERT ls_shipping INTO TABLE lt_shipping. CLEAR: ls_changed_fields. ls_changed_fields-ref_guid = <item_link>-guid_hi. ls_changed_fields-objectname = 'SHIPPING'. ls_changed_fields-ref_kind = 'B'. APPEND 'INCOTERMS2' TO ls_changed_fields-field_names. INSERT ls_changed_fields INTO TABLE lt_changed_fields. CALL FUNCTION 'CRM_ORDER_MAINTAIN' EXPORTING it_shipping = lt_shipping CHANGING ct_input_fields = lt_changed_fields EXCEPTIONS error_occurred = 1 document_locked = 2 no_change_allowed = 3 no_authority = 4. IF sy-subrc <> 0. WRITE: / 'error during quantity change'. RETURN. ENDIF.
Execute the report, specify new incoterms for header and item:
And use the following code to capture the change:
DATA: lt_update TYPE crmt_shipping_du_tab,
lt_insert TYPE crmt_shipping_du_tab,
lt_delete TYPE crmt_shipping_du_tab,
lt_guid TYPE crmt_object_guid_tab.
DO 2 TIMES.
CLEAR: lt_guid.
IF sy-index = 1.
APPEND <head>-guid TO lt_guid.
ELSE.
APPEND <item>-guid TO lt_guid.
ENDIF.
CALL FUNCTION 'CRM_ORDER_UPDATE_TABLES_DETERM'
EXPORTING
iv_object_name = 'SHIPPING'
iv_field_name_key = 'GUID'
it_guids_to_process = lt_guid
iv_header_to_save = lv_srvo_guid
IMPORTING
et_records_to_insert = lt_insert
et_records_to_update = lt_update
et_records_to_delete = lt_delete.
READ TABLE lt_update ASSIGNING FIELD-SYMBOL(<update>) INDEX 1.
IF <update> IS ASSIGNED.
CASE sy-index.
WHEN 1.
WRITE:/ |changes on header, new incoterms: { <update>-incoterms2 }| COLOR COL_GROUP.
WHEN 2.
WRITE:/ |changes on item, new incoterms: { <update>-incoterms2 }| COLOR COL_KEY.
ENDCASE.
ENDIF.
ENDDO.
And you will see the output, the change is detected correctly as expected.
