MDM ABAP API Performance Problems

Question

Hi all,
we developed a custom transaction into our ECC 6.0 system to remotely retreive data coming from MDM (7.1 SP05) and show them to the user. The 2 systems phisically reside in different datacenters, so running in the same WAN but in 2 different AD domains and 2 different ip networks.
In short the transaction is working using the standard MDM ABAP API functionalities and getting the MDM data using the following methods:
      CALL METHOD lr_api->mo_accessor->connect
      CALL METHOD lr_api->mo_core_service->query
      CALL METHOD lr_api->mo_core_service->retrieve
      CALL METHOD lr_api->mo_accessor->disconnect.
This is working, but with awful performances. for example to get a subset of materials (around 500 codes) it takes more than 1 minute, and the quantity of data transfered from MDM to ECC (around 30 KB) is not justifying this time.
Please be so kind to suggest any kind of activity that I can perform to improve the situation.
Thanks in advance.

Answer 1

I am trying to retreieve date from MDM to ECC using ABAP API.I am getting the below dump.
Short text
    An exception occurred that was not caught.
What happened?
    The exception 'CX_MDM_PROVIDER' was raised, but it was not
     along
    the call hierarchy.
    Since exceptions represent error situations and this error
    adequately responded to, the running ABAP program
     'CL_MDM_PROVIDER_71_SP00_PL00==CP' has to be
    terminated.
What can you do?
    Note down which actions and inputs caused the error.
    To process the problem further, contact you SAP system
    administrator.
    Using Transaction ST22 for ABAP Dump Analysis, you can loo
    at and manage termination messages, and you can also
    keep them for a long time.
Error analysis
    An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_MDM_PROVIDER', was not caught in
procedure "GET_LOC_SUPP" "(METHOD)", nor was it propagated by a RAISING clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
Internal error: field 'SEARCH_GROUPS' not found; contact your system
administrator
Please check at this point I am getting dump:

SY-REPID
I am picking the data from MAIN TABLE MDM_SUPPLIER_MAP and below is the code.
CALL METHOD lv_mdm_api->mo_core_service->query
      EXPORTING
*Main Table
      iv_object_type_code = 'MDM_SUPPLIER_MAP'               "#EC NOTEXT
*      it_query = lt_query
      IMPORTING
      et_result_set = lt_result_set.
Please suggest solution to get the records from MDM to ECC.
When I am tring to replace the abpove with the below code it is working.But in this case I need to retreive all the data instead of using DO and ENDO.Could any please suggest solution.
DO 10 TIMES.
APPEND sy-index TO keys.
ENDDO.
CALL METHOD lv_mdm_api->mo_core_service->retrieve_simple
EXPORTING
iv_object_type_code = 'MDM_SUPPLIER_MAP'
it_keys = keys
IMPORTING
et_ddic_structure = result_ddic
