Code Optimization - Performance Issue

Former Member — Mon, 18 Feb 2008 15:17:59 GMT

Dear All,

I have written the below code, which basically does what CS15 does, since it is recursive in nature, the execution time is very long. Is there anyway i can modify this code, to reduce the run-time.

Function call
IMPORTING
TOPMAT =

IF VA_REF NE EBAN-MATNR. WHILE NOT VA_MATNR IS INITIAL. CALL FUNCTION 'CS_WHERE_USED_MAT' EXPORTING DATUB = SYST-DATUM DATUV = SYST-DATUM MATNR = VA_MATNR WERKS = EBAN-WERKS TABLES WULTB = IT_WULTB[] EQUICAT = IT_EQUICAT[] KNDCAT = IT_KNDCAT[] MATCAT = IT_MATCAT[] STDCAT = IT_STDCAT[] TPLCAT = IT_TPLCAT[] PRJCAT = IT_PRJCAT[] EXCEPTIONS CALL_INVALID = 1 MATERIAL_NOT_FOUND = 2 NO_WHERE_USED_REC_FOUND = 3 NO_WHERE_USED_REC_SELECTED = 4 NO_WHERE_USED_REC_VALID = 5. IF SY-SUBRC EQ 0. LOOP AT IT_MATCAT[] INTO HT_MATCAT FROM '0'. SEARCH HT_MATCAT-MATNR FOR 'MM'. IF SY-FDPOS NE SPACE AND VA_MM IS INITIAL. VA_MM = 'X'. CONCATENATE 'NUT' '~' A_MTL INTO A_MTL. ENDIF. SEARCH HT_MATCAT-MATNR FOR 'DM'. IF SY-FDPOS NE SPACE AND VA_PM IS INITIAL. VA_PM = 'X'. CONCATENATE 'WASHER' '~' A_MTL INTO A_MTL. ENDIF. SEARCH HT_MATCAT-MATNR FOR 'CM'. IF SY-FDPOS NE SPACE AND VA_CM IS INITIAL. VA_CM = 'X'. CONCATENATE 'SPRING' '~' A_MTL INTO A_MTL. ENDIF. ITAB-MATNR = HT_MATCAT-MATNR. APPEND ITAB. CLEAR ITAB. ENDLOOP. ENDIF. CLEAR: VA_MATNR, HT_MATCAT. REFRESH IT_MATCAT[]. READ TABLE ITAB INTO VA_MATNR INDEX VA_KEY. "Value assignment VA_KEY = VA_KEY + 1. ENDWHILE. ENDIF. VA_REF = EBAN-MATNR.

Any inputs????

May be you can avoid the SEARCH HT_MATCAT-MATNR. If your MM CM DM are coming in an exact position in MATNR field

Say for example in MT_MATCAT-MATNR is something like 'MATMM001' or 'MATDM001' or 'MATCM001'

then

if MT_MATCAT-MATNR+3(2) = 'MM' AND VA_MM IS INITIAL.

VA_MM = 'X'.

CONCATENATE 'NUT' '~' A_MTL INTO A_MTL.

ENDIF.
