performance problem

[Former Member]

Hi Experts ,

Following routine taking long time, it takes around 1 hour for 34,000 records.

IT_ANLA is sorted and no duplicate entries in the table.

Is there any way to improve performance for this ?

FORM GET_FIAA_ANLC_VALUES_GET.

DATA : LV_GJAHR LIKE ANLC-GJAHR.

LV_GJAHR = S_GJAHR-LOW.

LOOP AT IT_ANLA.

REFRESH LT_ANLC.

CALL FUNCTION 'FIAA_ANLC_VALUES_GET'

EXPORTING

I_ANLN1 = IT_ANLA-ANLN1

I_ANLN2 = IT_ANLA-ANLN2

I_BUKRS = IT_ANLA-BUKRS

I_GJAHR = LV_GJAHR

TABLES

T_ANLC = LT_ANLC[]

EXCEPTIONS

NOT_FOUND = 1

ERR_IN_DEPR_REC = 2

OTHERS = 3.

IF SY-SUBRC = 0.

APPEND LINES OF LT_ANLC TO LT_ANLC_FINAL.

ENDIF.

ENDLOOP.

ENDFORM.

what do you want to know?

This function is in the loop, CALL FUNCTION 'FIAA_ANLC_VALUES_GET',

what is it doing?

The only thing I can say, if the fuinction could process the whole table IT_ANLA

then it would be faster.

There is very little you can do to remedy your situation. I believe that the performance degradation is taking place in the SAP function module. On your part there is very little you can do. I have modified you program a little. Have a look at it.

FORM get_fiaa_anlc_values_get.

  DATA : lv_gjahr LIKE anlc-gjahr.

* MARK START OF INSERTION
  DATA: it_anla_tmp LIKE TABLE OF it_anla. 

  it_anla_tmp[] = it_anla[]. 
  
  SORT it_anla BY anln1 anln2 bukrs.
  
  DELETE ADJACENT DUPLICATES FROM it_anla COMPARING anln1 anln2 bukrs.
* MARK END OF INSERTION  


  lv_gjahr = s_gjahr-low.

  
  LOOP AT it_anla.

    REFRESH lt_anlc.

    CALL FUNCTION 'FIAA_ANLC_VALUES_GET'
