本文章向大家介绍ABAP Debugging Script(调试器脚本)使用的一些实际例子，主要内容包括其使用实例、应用技巧、基本知识点总结和需要注意事项，具有一定的参考价值，需要的朋友可以参考一下。

例子1：Use ABAP debugger script to view BOL entity content in an efficient way

In CRM, if we could like to review a BOL entity content in debugger, for example consider the following sample code which fetches line item product of a given one order document:

DATA:
      lo_collection      TYPE REF TO if_bol_entity_col,
      lv_view_name       TYPE crmt_view_name,
      lv_query_name      TYPE crmt_ext_obj_name,
      ls_parameter       TYPE genilt_query_parameters,
      lt_query_parameter TYPE genilt_selection_parameter_tab,
      ls_query_parameter LIKE LINE OF lt_query_parameter.

    ls_query_parameter-attr_name = 'OBJECT_ID'.
    ls_query_parameter-low = iv_oppt_id.
    ls_query_parameter-option = 'EQ'.
    ls_query_parameter-sign = 'I'.
    APPEND ls_query_parameter TO lt_query_parameter.

    ls_query_parameter-attr_name = 'PROCESS_TYPE'.
    ls_query_parameter-low = iv_process_type.
    ls_query_parameter-option = 'EQ'.
    ls_query_parameter-sign = 'I'.
    APPEND ls_query_parameter TO lt_query_parameter.

    so_core = cl_crm_bol_core=>get_instance( ).
    so_core->load_component_set( 'BT' ).
    lv_query_name = 'BTQ1Order'.

    DATA(lo_result) = so_core->dquery(
        iv_query_name               = lv_query_name
        is_query_parameters         = ls_parameter
        it_selection_parameters             = lt_query_parameter
        iv_view_name                = lv_view_name ).

    CHECK lo_result->size( ) = 1.
    DATA(lo_order_result) = lo_result->get_first( ).

    DATA(lo_bt_order) = lo_order_result->get_related_entity( 'BTADVS1Ord' ).
    CHECK lo_bt_order IS NOT INITIAL.

    DATA(lo_header) = lo_bt_order->get_related_entity( 'BTOrderHeader' ).

    CHECK lo_header IS NOT INITIAL.

    DATA(lo_items) = lo_header->get_related_entities( iv_relation_name = 'BTHeaderItemsExt' ).
    CHECK lo_items->size( ) = 1.

    DATA(lo_item) = lo_items->get_first( ).

    DATA(lo_admini) = lo_item->get_related_entity( 'BTItemsFirstLevel' ).
    CHECK lo_admini IS NOT INITIAL.

    DATA(lo_product) = lo_admini->get_related_entity( 'BTItemProductExt' ).

If you would like to review the content of lo_product, you have to:

(1) double click container_proxy：

(2) double click DATA_REF:

(3) double click:

(4) double click ATTRIBUTE_REF:

(5) double click:

So totally you need to perform FIVE times double click in order to review content:

Using ABAP debugger script

(1) Click Script tab:

(2) Create a new script:

Choose a name for your script:

(3) Use the following source code to overwrite the default source code:

Once done, save the script and choose “Execute Directly”.

(4) Before you start Script by clicking button “Start Script”, make sure you use the correct variable name used in your ABAP code. In my example, it is “LO_PRODUCT”.

Once done, click button “Start Script”: the BOL entity content is now automatically displayed, without five times double click any more.

例子2：Use ABAP debugger script to view dynamic query service selection parameter in an efficient way

In WebUI we can maintain search parameter for dynamic search:

The value maintained in WebUI could be found from dynamic query service instance in backend via debugging. Double click variable qs:

We need the following FIVE steps to see the selection parameter value.

(1) double click SELECTION_PARAM_COL:

(2) Double click ENTITY_LIST:

(3) These four entities represent the four selection parameters we see in WebUI. Double click one of them:

(4) Double click PARAMETER_DATA:

(5) double click:

Finally we see the value:

Use ABAP debugger script to directly review variable content without so many double clicks

(1) Click Script tab, create a new Script:

(2) Choose a name for your script:

Paste the following source code to overwrite automatically generated source code:
