# Implement Business Rules Logic in Custom Business Object
<!-- description --> Modify the business rules logic in custom business object to invoke the business rules for bonus percentage calculation of custom business object.

## Prerequisites
  - S/4HANA Cloud system must be of release 1811 or higher.
  - Custom Business Object must already be created in S/4HANA Cloud.
  - Business rules must be created in SAP Cloud Platform and deployed in S/4HANA cloud.

## You will learn
  - How to extend custom business object to integrate business rules logic
  - Run the custom business object to see the change in the values based on business rules execution

---

### Open custom business object


1. Open the `Bonus Plan` custom business object in S/4HANA cloud system.

2. Switch to **Logic** tab.

3. Click the **After Modification** link.

### Integrate rules logic in custom business object


4. Copy this code appropriately after `consistency check` block.

    > In the code do not forget to replace:        `bonusplanbusinessrules` with your custom business object name and rule service ID in ABAP function call `cl_fdt_brs_processor`  

   ```ABAP
   TYPES : BEGIN OF ts_bonus,
           percentage_value TYPE c LENGTH 3,
         END OF ts_bonus,
         tt_bonus TYPE TABLE OF ts_bonus.

   TYPES : BEGIN OF ts_bplan,
           high_bonus_assign_factor TYPE int4,
           low_bonus_assign_factor  TYPE int4,
           validity_end_date        TYPE d,
           validity_start_date      TYPE d,
         END OF ts_bplan.

   DATA : lr_data       TYPE REF TO data,
        lr_bonus      TYPE REF TO data,
        lt_name_value TYPE cl_fdt_brs_processor=>t_name_value,
        ls_name_value LIKE LINE OF lt_name_value,
        lt_data       TYPE tt_bonus,
        ls_input      TYPE ts_bplan.

   FIELD-SYMBOLS : <la_any>   TYPE ANY TABLE,
                 <lv_field> TYPE any,
                 <ls_bonus> TYPE data.

   DATA(lo_dsm) = cl_fdt_brs_processor=>get_instance( EXPORTING iv_function_id = '2ad0fa9edf294a0482235917f728cba9' ).

   lo_dsm->get_data_object_reference( EXPORTING iv_data_object = 'BONUS_PLAN_TT'
                                    IMPORTING er_data = lr_bonus ).

   ls_input-validity_start_date = bonusplanbusinessrules-validitystartdate.
   ls_input-validity_end_date = bonusplanbusinessrules-validityenddate.
   ls_input-low_bonus_assign_factor = bonusplanbusinessrules-lowbonusassignmentfactor.
   ls_name_value-name = 'BONUS_PLAN_TT'.
   ls_name_value-value = REF #( ls_input ).
   APPEND ls_name_value TO lt_name_value.

   "Invoke
   *TRY.
     lo_dsm->process( IMPORTING ea_result = lt_data
                      CHANGING  ct_name_value  = lt_name_value ).

   *ENDTRY.

   READ TABLE lt_data INTO DATA(ls_data) INDEX 1.
   bonusplanbusinessrules-lowbonuspercentage_v = ls_data-percentage_value.

   IF bonusplanbusinessrules-id IS INITIAL.
   bonusplanbusinessrules-isconsistent = abap_false.
   ENDIF.
   ```

5. Click **Publish** to save and publish the changes.

### Test business rules logic


1. Switch back to the **General Information** tab of custom business object.

2. Click the **Go To Generated UI** link.

    ![run custom business object](https://raw.githubusercontent.com/sap-tutorials/abap-core-development/main/tutorials/abap-extensibility-cbo-rules-consumption/runcbo.png)

3. Click **Go** if you have bonus plan data created, or click **+** to create a new one.

    ![run custom business object](https://raw.githubusercontent.com/sap-tutorials/abap-core-development/main/tutorials/abap-extensibility-cbo-rules-consumption/go.png)

    > You can edit the `Low Bonus Assignment Factor` and save it to see the change in `Low Bonus Percentage`
