MAI Template assignment BADI implementation

Starting with SAP Focused Run FP01 BADI “BADI_TEMPLATE_ASSIGNMENT” is foreseen to be executed whenever a MAI configuration is done. In case an implementation is provided, it will be executed after all potential template candidates have been identified. This BADI Interface considers:

Already assigned templates, including manual assignments (which have been set application “Reconfigure Templates”)
Default templates which match the current product versions and software components which are installed on the current system

The method to be implemented contains the following parameters as follows:

IF_TEMPLATE_ASSIGNMENT~CHANGE_TMPL_ASSIGNMENTS_TO_MOS
IT_CONTEXT Importing Type CL_ALRT_CFG_MAI_API_ENQUIRY=>PASSED_TREE_ELEMENTS
IT_PRODUCT_MAPPING Importing Type ACTPID_TO_CID_DIR_SORTED
CT_TEMPLATE_ASSIGNMENT_TO_MO Changing Type ACT_TMPL_ASSIGNMENT_TO_MO

Structure of the LMDB objects looks like this:

Structure of list of products has following structure:

1 "Get System type" for each Managed Object example:

Use the class cl_lmdb_mai_hier_tree_element to access the technical system or attributes which are related to the LMDB object.

CL_LMDB_MAI_HIER_TREE_ELEMENT=> IF_LMDB_MAI_HIER_TREE_ELEMENT~GET_PARENT
                  (Host -> Logical Host -> Technical Instance -> Technical system)
                  (Database Instance -> Database)
CL_LMDB_MAI_HIER_TREE_ELEMENT=> IF_LMDB_MAI_HIER_TREE_ELEMENT~GET_GENERIC_CIM_PROPERTY_VALUE
                  Importing   CIM_CLASS_NAME  'SAP_ApplicationSystem'
                              PROPERTY_NAME   'itadministrationrole'
                  Returning   RESULT

Example of CIM Instance Properties values reading: “ITAdministrationRole”.

2 Get the Templates that can be assigned to the Managed Object

 DATA:
    iv_template_id      TYPE ac_guid,
    lr_context          TYPE REF TO cl_alrt_cfg_mai_api_enquiry=>passed_tree_element,
    lr_product          TYPE REF TO acpid_to_cid_dir,
    lr_template         TYPE REF TO acs_template_assignment,
    iv_searchstring     TYPE string VALUE '<my special Template>',
    template_assignment TYPE REF TO acs_tmpl_assignment_to_mo
    .
…
* multiple products can be assigned to a single LMDB object
LOOP AT it_product_mapping REFERENCE INTO lr_product WHERE context_id EQ lr_context->context_id.
   cl_mai_rep_initializer=>initialize( EXPORTING iv_technical_scenario = lr_product->tech_scenario "pass the technical scenario/monitoring use case (eg: T_SYS_MON for Technical system monitoring)"
 
IMPORTING eo_assignment_factory = DATA(lo_assignment_factory)
          eo_template_factory   = DATA(lo_template_factory) ).
TRY.
   DATA(lo_context_store) = cl_alrt_cfg_store_contextdir=>get_instance( ).
   DATA(lo_managed_object) = lo_context_store->get_context_model( iv_context_id = lr_context->context_id ).              "Pass the context id"
   DATA(li_assignment) = lo_assignment_factory->get_assignment( ii_managed_object   = lo_managed_object  io_template_factory = lo_template_factory  ).
   DATA(lt_fitting_templates) = li_assignment->get_fitting_templates( iv_technical_scenario = lr_product->tech_scenario ). "pass the technical scenario/monitoring use case" ).
CATCH cx_alrt_cfg_directory_root.
 
* do error handling here…
ENDTRY.
CHECK lt_fitting_templates IS NOT INITIAL.

3 Change the template assigned to the Managed Object

Choose one template that meet special requirement, for example, the template with name start with Z_< ITAdministrationRole >, modify the template ID from CT_TEMPLATE_ASSIGNMENT_TO_MO.

LOOP AT lt_fitting_templates REFERENCE INTO lr_template.
    IF lr_template->template_ref->get_name( )  CS iv_searchstring.
        iv_template_id = lr_template->template_id.
    READ TABLE ct_template_assignment_to_mo
    WITH TABLE KEY
        context_id = lr_context->context_id product_id = lr_product->product_id REFERENCE INTO template_assignment.
        IF sy-subrc EQ 0.
            template_assignment->template_id = iv_template_id.
        ENDIF.
    ENDIF.
ENDLOOP.
