MAI Templates 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.

Example 
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

List of fitting templates 
 DATA:

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.

Change template
