How to get fast one entry of an returning table ?

Question

Hello experts,
I'm calling a method (see example) and after receiving the returning table
I just want select one entry of this tabel. How can I do this with fast perfomrance ?
AT the moment I am doning this with a loop, but I need something faster !
      DATA: EV_PARTNER TYPE BU_PARTNER.
      DATA: ET_ATTRIBUTES TYPE /MRSS/T_FIELDNAME_VALUE_TAB.
      DATA: RT_PARTNER TYPE /MRSS/T_PARTNER_TAB.
      DATA: WA_PARTNER TYPE TABLE OF /MRSS/T_PARTNER_TAB.
      DATA: WAA_PARTNER TYPE LINE OF /MRSS/T_PARTNER_TAB.
      DATA: PARTNER_ROLE(2) TYPE C.
      PARTNER_ROLE = 'WE'.
      IF LV_PARTNER = ''.
        CALL METHOD <FS_ITEM>-OBJECT->PARTNER_GET
          RECEIVING
            RT_PARTNER = RT_PARTNER.
        LOOP AT RT_PARTNER INTO WAA_PARTNER.
          IF WAA_PARTNER-PARTNER_ROLE = 'WE'.
            LV_PARTNER = WAA_PARTNER-PARTNER_ID.
            EXIT.
          ENDIF.
        ENDLOOP.
      ENDIF.
Thanks,
Gerd

Hi,
Instead of looping in to a work area and then chekcing the condition , you can directly specify the condition in the loop by which the loop will only execute on those which satisfy the condition thereby making it much faster
DATA: EV_PARTNER TYPE BU_PARTNER.
DATA: ET_ATTRIBUTES TYPE /MRSS/T_FIELDNAME_VALUE_TAB.
DATA: RT_PARTNER TYPE /MRSS/T_PARTNER_TAB.
DATA: WA_PARTNER TYPE TABLE OF /MRSS/T_PARTNER_TAB.
DATA: WAA_PARTNER TYPE LINE OF /MRSS/T_PARTNER_TAB.
DATA: PARTNER_ROLE(2) TYPE C.
PARTNER_ROLE = 'WE'.
IF LV_PARTNER = ''.
CALL METHOD <FS_ITEM>-OBJECT->PARTNER_GET
RECEIVING
RT_PARTNER = RT_PARTNER.
LOOP AT RT_PARTNER where partner_role = 'WE'.
LV_PARTNER = RT_PARTNER-PARTNER_ID.
EXIT.
ENDLOOP.
