Interpret argument as number

[Former Member]

Hello,

in my startroutine I'd like to interpret an argument as number. Problem is, that the name of the argument should be created during runtime. During dataload I got the error message, that argument can not interpreted as number.

Here is the code:

DATA:

          lv_time           TYPE N LENGTH 3,

          lv_validfrom      TYPE N LENGTH 2,

          lv_month          TYPE C LENGTH 30.

DO 3 TIMES.

     CONCATENATE 'wa_source_package-month' lv_time INTO lv_month.

      wa_source_package-amount = lv_month.

       COLLECT wa_source_package INTO SOURCE_PACKAGE.


       lv_time = lv_time + 1.

ENDDO.

Many thanks for your help.

lv_time           TYPE N LENGTH 3,

this would have leading zeroes, pls check in debug once, better to have type i

Hello Kartik,

I checked that and get the same error message.

Kind regards

Hi Ella Rose,

After this Line.

CONCATENATE 'wa_source_package-month' lv_time INTO lv_month

You can check with Condense with NO-GAPS.

Condense lv_month NO-GAPS.

wa_source_package = lv_month.

COLLECT wa_source_package INTO SOURCE_PACKAGE.

Check with the tabel type also .

I hope this will be helpful.

Thanks & Regards,

can u paste the values as you see in debug.

[Former Member]

I get the an error message again.

In debug I see following values:

lv_time -> 1

lv_month -> wa_source_package-month1

In lv_month I need the value of wa_source_package-month1 (in this example it would be 1000,00) and not the argument.

[Former Member]

I mean that system should interpret wa_source_package-month1.

[Former Member]

ohh ofcourse.

Remove the quotes from 'wa_source_package-month' in the concatenate.

Raymond's code makes sense, I missed pay attention to the o/p u were trying to achieve

Use a field-symbol :

FIELD-SYMBOLS: <value> TYPE wa_source_package-amount. " Adapt

CONCATENATE 'MONTH' lv_time INTO lv_month.
ASSIGN COMPONENT lv_month OF STRUCTURE wa_source_package TO <value>.
wa_source_package-amount = <value>.

Alternative : use a DO VARYING (beware :  obsolete form of statement)

DO 3 TIMES VARYING lv_month FROM wa_source_package-month1 NEXT wa_source_package-month2.
   wa_source_package-amount = lv_month.
   COLLECT wa_source_package INTO source_package.
ENDDO.

Hello Raymond,

with field symbols it works. There is a little misstake in your code.

DO 3 TIMES VARYING lv_month FROM wa_source_package-month1 NEXT wa_source_package-month2.

          wa_source_package-amount = lv_month.

          COLLECT wa_source_package INTO source_package.

ENDDO.

I get an error message but with following code it works fine.

DO 3 TIMES VARYING <value> FROM wa_source_package-month1 NEXT wa_source_package-month2.

          wa_source_package-amount = <value>.

          COLLECT wa_source_package INTO source_package.

ENDDO.

Many thanks for your answer.

I forgot to add the DATA or FIELD-SYMBOLS statement to define the dynamic field for the second option
