How to Update crmd_customer_h TABLE Using CRMV_EVENT Through Funtion Module

Question

Hi
How we can update customer_h table using the CRMV_EVENT Where i implemented logic below in the Funtion Module.
data:     lt_doc_flow          TYPE crmt_doc_flow_wrkt,
          lw_cust_h_com        TYPE crmt_customer_h_com,
          lw_input_field_names TYPE crmt_input_field_names,
          lt_input_field_names TYPE crmt_input_field_names_tab,
          lt_objects_to_save TYPE crmt_object_guid_tab,
          lw_guid TYPE CRMT_OBJECT_GUID.
DATA : lv_process_type TYPE crmt_process_type.
data: wa_doc_flow type CRMT_DOC_FLOW_WRK.
data: wa_customer_h type crmd_customer_h.
*  Function module for retriving the Process type.
  CALL FUNCTION 'CRM_ORDERADM_H_READ_OW'
    EXPORTING
      iv_orderadm_h_guid     = iv_header_guid
    IMPORTING
      ev_process_type        = lv_process_type
    EXCEPTIONS
      admin_header_not_found = 1
      OTHERS                 = 2.
if lv_process_type eq 'ZG01'.
CALL FUNCTION 'CRM_DOC_FLOW_READ_OB'
EXPORTING
   IV_HEADER_GUID                 = iv_header_guid
IMPORTING
   ET_DOC_FLOW_WRK                = lt_doc_flow.
read table lt_doc_flow with key objtype_a = 'BUS2000116' INTO wa_doc_flow. "gc_object_type-service.
            if sy-subrc eq 0.                    "set flag for service order
            lw_cust_h_com-ref_guid       =  wa_doc_flow-objkey_a.
            lw_cust_h_com-ZZTRAIL_FLAG   = 'X'.
             lw_cust_h_com-mode           = 'A'.
            lw_cust_h_com-ref_handle     = '0000000001'.
            lw_guid = wa_doc_flow-objkey_a.
            INSERT lw_guid INTO TABLE lt_objects_to_save.
     endif.
              lw_input_field_names-fieldname = 'REF_GUID'.
            lw_input_field_names-fieldname = 'ZZTRAIL_FLAG'.
          lw_input_field_names-changeable = ' '.
           INSERT lw_input_field_names INTO TABLE lt_input_field_names.

                is_customer_h_com    = lw_cust_h_com
              CHANGING
                ct_input_field_names = lt_input_field_names
              EXCEPTIONS
                header_change_error  = 1
                header_create_error  = 2
               error_occurred       = 3.
ENDIF.
*endif.
*Clearing local variables
  clear: lv_process_type,
         lw_cust_h_com,
         lw_input_field_names.
*Free internal tables
  free: lt_doc_flow,
        lt_input_field_names.

Hi Faisal
I think your not clear with what i am saying anyhow i will again explain you my requirement
As per my requirement
1)in the service order search report i need to add a field called "Has trail order with No Follow up" with values "Yes" & "Blank"
For above Field i added  using the structure CRMST_QUERY_SRVO_BTIL and through configuration i am able to display the field in webui as per (Attachement Pic 1)
2)When i  search with search criteria as  "Has trail order with No Follow up" with  "Yes"
Then in result list i need to show the service order those having follow up as trail orders(sales order) only.if for  next document trail order  having any follow up then those service orders dont want to show in result list.
For above requirement i implemented F.M using CRMV_EVENT & I configured for BUS2000115 And BEFORE_SAVE The Order
The FM Will get trigger when i save the service order and for that service order if create any follow up and try to save the trail order then This FM Will trigger and in this i am doing validations.
3)Add one AET Trail Flag field is added under CUSTOMER_H Table.
4)in the FM I am validating for if the trail order having the preceding document as service order then i need to make flag as "X" For that service order in customer_h
if suppose when i delete trail order from the service order then that flag must need to be "unset" from the CUSTOMER_H.
Why bcoz we are doing above process is do show records in result list based on Flag values
these flag checks are validating in the BADI Which we implemented for search logic.
Please refer below Login for my requirement:-
Proposal to have a custom “flag” field (background at table level,
     crmd_customer_h) linked to service order which gets flagged whenever at
     least one Trial order is created and saved from the Service Order.
The flag value should be cleared when all the trial orders created and
saved as follow up transactions are deleted from the system.
Similarly for Trial Orders will use the same custom “flag” field
     which gets activated when at least one follow up is created and saved from Trial Order.
The flag value should be cleared when all the follow up transactions from
the Trial Order are deleted from the system.
When the above search criteria “Has Trial order with no follow up”
     “is” “Yes” is applied then the logic derives all the service
     orders which satisfy additional search criteria applied in the search and
     for these Service orders checks if the custom flag field is checked to
     derive all Service orders which have Trial order. The custom flag values
     values are derived from crmd_customer_h table in CRM.
4 )Further for all the Trial Orders determined in Step 3
check if the Trial Order has a follow up by checking if the custom flag field
is checked. The custom flag values are derived from crmd_customer_h table in
CRM.
5) If step 4 is not met populate the preceding Service
Orders in the Result list
