Moving parameters in other with differenct data type

[TimVDB92]

Hi,

I want to check if it's possible to convert one parameter in an other.

For example when I want to move a string to a data, the move should go in exception.

I was trying this with following code, but the code is just converting a string in a data, without going in exception.

DATA: lv_var1 type String.

DATA: lv_var2 type DATUM.

lv_var1 = 'Test'

TRY.

     MOVE lv_var1 TO lv_var2.

CATCH cx_sy_conversion_error into Exception

     RETURN Exception.

ENDTRY.

Result: lv_var2 = 'Test'

=> I want the program to check 2 parameters and return an exception, but this is not happening

Dear Tim,

As the datum type is a 8 charater field, you don't have a conversion error. Try to declare lv_var2 as a packed decimal:

data: lv_var2(8) type p.

and your exception will work.

If this suits you; please award points.

Regards,

Hans

Hi.

The problem is, that the Date-Field is a CHAR8 , so it is compatible with string and there is no exception. I have an idea, but I don't know, if it solves your problem:

  With DESCRIBE FIELD you can check the Datatypes:

     DESCRIBE FIELD lv_var1 TYPE lv_typ1.   " LV_TYP1 = 'g'
     DESCRIBE FIELD lv_var2 TYPE lv_typ2.   " LV_TYP2 = 'D'
     if lv_typ1 = lv_typ2.
       ....

     endif.

  But this tests, if the Types are identical, not only compatible. A char Field is not identical to a string.

The sap F1-Help shows you the values for every Datatype.

regards,

Peer

How is it possible that I can MOVE a String into an Integer or String?

None of both solutions are working for me :s

Hello.

That should be no problem:

DATA: lv_int TYPE i,
         lv_string TYPE string.

   lv_int = 15.
   MOVE lv_int TO lv_string.
   WRITE:/ lv_int,lv_string.

   lv_string = '2'.
   MOVE lv_string TO lv_int.
   WRITE:/ lv_int,lv_string.

Output:

   15  15

    2  2

If the string has a non-numeric value, it will dump. But in this case you can use the TRY .. ENDTRY, as you wrote in the beginning.

  lv_string = 'x'.
   TRY.
       MOVE lv_string TO lv_int.
       WRITE:/ lv_int,lv_string.
     CATCH cx_sy_conversion_error.
       WRITE:/ 'error'.
   ENDTRY.
