how to do comparison in a loop.

Former Member — Mon, 06 Jul 2009 12:07:06 GMT

Hi all,

TYPES: BEGIN OF ZROUTE,

VBELN TYPE VBELN,

ROUTE TYPE ROUTE,

END OF ZROUTE.

DATA : IT_ZROUTE TYPE STANDARD TABLE OF ZROUTE,

WA_ZROUTE TYPE ZROUTE.

LOOP AT I_XVTTP_TAB INTO LW_XVTTP.

WA_ZROUTE-VBELN = LW_XVTTP-VBELN.

SELECT SINGLE ROUTE

INTO WA_ZROUTE-ROUTE

FROM LIKP

WHERE VBELN = LW_XVTTP-VBELN

APPEND WA_ZROUTE TO IT_ZROUTE.

ENDLOOP.

results from IT_ZROUTE

vbeln route

1111 A

2222 B

I have some problem in with the code below. I tried to collect vbeln and route into IT_ZROUTE.

However, after i've got the result, i want to do distiguish between the route.

If route A ne route B, then display an error messages.

My problem is, how do i compare the record by looping IT_ZROUTE? if i set into a temporary variable, the value will always change and i have prb in doing the comparison. eg:

loop it_zroute into wa_route.

zroute = wa_route-route. "set into a variable

if zroute = wa_route-route

"display error message

endif.

endloop.

Could anyone give me some tips to enhance my code? Really appreciate your help.

Hi,

try using 'AT END OF'..



* To fetch the coverage count for each order line
  LOOP AT it_zroute into wa_route.
    lv_count = wa_route-route.
    AT END OF route.
      check with the previous value.
     give error message.
 
    ENDAT.
  ENDLOOP.

Hi,

loop at i_zroute into wa_route.

if zroute = space .

zroute = wa_route.

else.

if zroute = wa_route. " I dont know you want to compare = or NE change accordingly

Error Message........

endif.

endloop.

Hi,

You can use "On change of" to display error messages accordingly.

Hi dear,

Please look paste the following code that will bring the result what you want :

TYPES: BEGIN OF ZROUTE,

VBELN TYPE VBELN,

ROUTE TYPE ROUTE,

END OF ZROUTE.

DATA : IT_ZROUTE TYPE STANDARD TABLE OF ZROUTE,

WA_ZROUTE TYPE ZROUTE.

LOOP AT I_XVTTP_TAB INTO LW_XVTTP.

WA_ZROUTE-VBELN = LW_XVTTP-VBELN.

SELECT SINGLE ROUTE

INTO WA_ZROUTE-ROUTE

FROM LIKP

WHERE VBELN = LW_XVTTP-VBELN

read table it_zroute with key route = wa_zroute-route.

if sy-subrc = 0.

message 'You have already entered the route' type 'E'.

else.

APPEND WA_ZROUTE TO IT_ZROUTE.

endif.

ENDLOOP.

Hi SW,

You should never use SELECT statement inside LOOP statement as it will affect performance of the program. Use FOR ALL ENTRIES for the same.

TYPES: BEGIN OF ZROUTE,

VBELN TYPE VBELN,

ROUTE TYPE ROUTE,

END OF ZROUTE.

DATA : IT_ZROUTE TYPE STANDARD TABLE OF ZROUTE,

WA_ZROUTE TYPE ZROUTE.

************Addition STARTS***********

data : I_XVTTP_TAB_temp like I_XVTTP_TAB occurs 0 with header line.

data : begin of likp_itab occurs 0,

vbeln like likp-vbeln,

route like likp-route,

end of likp_itab.

I_XVTTP_TAB_temp[] = I_XVTTP_TAB[].

sort I_XVTTP_TAB_temp by vbeln.

delete adjacent duplicates from I_XVTTP_TAB_temp comparing vebln.

select vbeln

route

into table likp_itab

for all entries in I_XVTTP_TAB_temp

where vbeln eq I_XVTTP_TAB_temp-vbeln.

if sy-subrc eq 0.

sort likp_itab by vbeln.

endif.

************Addition ENDS***************

LOOP AT I_XVTTP_TAB INTO LW_XVTTP.

WA_ZROUTE-VBELN = LW_XVTTP-VBELN.

****************Not required

SELECT SINGLE ROUTE

INTO WA_ZROUTE-ROUTE

FROM LIKP

WHERE VBELN = LW_XVTTP-VBELN

****************Not required

read table likp_itab witj key vbeln = LW_XVTTP-VBELN binary search.

if sy-subrc eq 0.

WA_ZROUTE-ROUTE = likp_itab-route.

endif.

APPEND WA_ZROUTE TO IT_ZROUTE.

*********Add

clear wa_zroute.

*********Add

ENDLOOP.

Please explain the later part again I am not clear with requirement.
