SAP WebClient UI component模型元数据解析工具

I use the issue in this  blog to demonstrate the usage of this small repository parse tool: We need to know under which enhancement set the component usage “ZCUSTOM” is added to UI component BT116H_SRVO.

This customizing activity could allow us to compare the runtime repository between the original UI component and the enhanced one:

However, if there are too many enhancement sets in the system, it could be very inefficient for manual comparison.

Fortunately the comparison could be done by code below.

The report is quite simple: (1) in line 9, get all enhancement sets list under which the UI component is enhanced. (2) get the enhanced BSP application name and page name in line 11 and 12, then get the component usage information for each enhanced BSP application via repository tool, then filter it by usage name “ZCUSTOM”.

REPORT zbsp.CONSTANTS: cv_host TYPE o2applname VALUE 'BT116H_SRVO'.DATA: lt_enh_sets TYPE bsp_dlct_ehset,
      ls_enh_set LIKE LINE OF lt_enh_sets,

   enhancement_set = lt_enh_sets-enhancement_set AND comp_name = cv_host.LOOP AT lt_enh_sets INTO ls_enh_set.
  READ TABLE lt_extension INTO ls_extension WITH KEY enhancement_set = ls_enh_set-enhancement_set comp_name = cv_host.
  IF sy-subrc = 0.
    CLEAR: lt_usages.
    CALL METHOD zcl_view_repo_tool=>get_repo_metadata(
        iv_comp_name = ls_extension-bsp_appl
        iv_page_name = ls_extension-rt_rep_page
        et_usages    = lt_usages ).
    READ TABLE lt_usages WITH KEY usage_name = 'ZCUSTOM' INTO ls_usage.
    IF sy-subrc = 0.
      WRITE: / 'EnhancementSet: ', ls_enh_set-enhancement_set,
      ' defines component usage to component: ', ls_usage-child_cmp_type.

The small parse tool zcl_view_repo_tool just parse the repository xml from database table and convert it to two internal tables which contains the view information and component usage information. Its source code could be found in attachment.

We can compare the report execution result and the manual check via customizing activity: they are exactly the same.

It seems the source code in attachment is lost after SCN is migrated to SAP community. Please use the following report instead:
