Balance gets reverted in Infotype 2006 (Absence Quota)

Question

Scenario:
staff has a balance of 36 availale with him and has entry in Infotype 2001 (for dates 13/12/2010 - 17/12/2010 -  ).i..e, 5 week days
Now if  the staff takes another leave on next working day i.e., 20/12/2010, system needs to deduct the weekend in between, ie. 18/19/2010
For this purpose i have written a code, where follwoing peace of cdoe is creaeting an abrupt situation.
i'm using the follwoing code.
[code]
REFRESH ABSENCE1.
in itab_pa2001 i get the original records from the system so need to get existing recrod from system
and limit the itab_pa2001 to only the week end record
THIS IS WORKING
  LOOP AT ITAB_PA2001.
    CALL FUNCTION 'BAPI_ABSENCE_GETDETAILEDLIST'
         EXPORTING
              EMPLOYEENUMBER   = ITAB_PA2001-PERNR
              TIMEINTERVALLOW  = ITAB_PA2001-BEGDA
              TIMEINTERVALHIGH = ITAB_PA2001-ENDDA
         IMPORTING
              RETURN           = RETURN
         TABLES
              ABSENCE          = ABSENCE1.
    IF RETURN-TYPE NE 'E' OR RETURN-TYPE NE 'A'
        OR RETURN-TYPE NE 'W'.
      LOOP AT ABSENCE1.
      ENDLOOP.
      DELETE ITAB_PA2001 WHERE
      BEGDA = ABSENCE1-VALIDBEGIN
      AND ENDDA = ABSENCE1-VALIDEND.
    ENDIF.
    REFRESH ABSENCE1.
  ENDLOOP.
  REFRESH ABSENCE1.
  CLEAR ABSENCE1.
now itab_pa2001 only having the week end record  follwoign code creates it
  LOOP AT ITAB_PA2001.
    STATUS = 'TRUE'.
    CALL FUNCTION 'BAPI_ABSENCE_CREATE'
         EXPORTING
              EMPLOYEENUMBER = ITAB_PA2001-PERNR
              VALIDITYBEGIN  = ITAB_PA2001-BEGDA
              VALIDITYEND    = ITAB_PA2001-ENDDA
              ABSENCETYPE    = ITAB_PA2001-SUBTY
         IMPORTING
              RETURN         = RETURN.
    IF RETURN-TYPE EQ 'E' OR RETURN-TYPE EQ 'A' OR RETURN-TYPE EQ 'W'.
      WRITE : RETURN-MESSAGE.
      NEW-LINE.
    ENDIF.
  ENDLOOP. [code]
what happens
Balance before was 36
now  it is 36 - 5 + 2 = 33.
i.e., 36 - days of old entry + days of new entry.
is using 'BAPI_ABSENCE_GETDETAILEDLIST' and 'BAPI_ABSENCE_CREATE' incorrect.

Answer 1

Found the solution 
can not use
'BAPI_ABSENCE_GETDETAILEDLIST'
and
'BAPI_ABSENCE_CREATE'  in sequence
as the internal table p2001 called in 'BAPI_ABSENCE_GETDETAILEDLIST' does not get refreshed fro the next call to 'BAPI_ABSENCE_CREATE' as they are in the same function group.
using "BAPI_PTMGRATTABS_MNGCREATION" instead of 'BAPI_ABSENCE_CREATE'.
