declaring data type dynamically

Former Member — Wed, 14 May 2008 05:44:08 GMT

Hi all

i am upgrading version 4.7 to 6.0.

In one of the program i came across following statements.

*Select * from (object_type-viewname) into work.*

object_type-viewname has some table name as value which changes with each loop pass.

Earlier in version 4.7 version the structure of work was flat,

but if i use the same in 6.0 it gives dump saying types not compatible.

So the only solution I was able to understand is every time *data type of work should be equal to contents of object_type-viewname.* But how do i achieve that

PLzzz help

Hi,

Try making the work area Dynamic; Take this eg:-


DATA : 
it_tab TYPE TABLE OF pa0002,
wa_tab LIKE LINE OF it_tab,
record TYPE REF TO data.

FIELD-SYMBOLS: <fs> TYPE ANY.

GET REFERENCE OF wa_tab INTO record.
ASSIGN record->* TO <fs>.
SELECT SINGLE * FROM pa0002
              INTO <fs>
              WHERE pernr = '1'. "some criteria for selection

I guess in your case, the problem is with work and not with object_type-viewname .

So, all you need to do is make it dynamic based on the above eg:-

Cheers,

Remi

Hi Shubhi,

Use the following code:

REPORT ZUPGRADE_BDC_ABAP1.


* Set of table names
DATA: IT_TABNAME TYPE TABLE OF DD03L-TABNAME,
      WA_TABNAME LIKE LINE OF IT_TABNAME.

* Field Symbols for the dynamic data creation
DATA LR_DATA TYPE REF TO DATA.

FIELD-SYMBOLS <FS> TYPE ANY TABLE.

CLEAR WA_TABNAME.

MOVE 'SPFLI' TO WA_TABNAME.
APPEND WA_TABNAME TO IT_TABNAME.

MOVE 'MARA' TO WA_TABNAME.
APPEND WA_TABNAME TO IT_TABNAME.


LOOP AT IT_TABNAME INTO WA_TABNAME.

*Dynamically creating the internal table
  IF <FS> IS ASSIGNED.
    UNASSIGN <FS>.
  ENDIF.

  CLEAR LR_DATA.

  CREATE DATA LR_DATA TYPE TABLE OF (WA_TABNAME).

  ASSIGN LR_DATA->* TO <FS>.

  SELECT * FROM (WA_TABNAME) INTO TABLE <FS> UP TO 10 ROWS.

ENDLOOP.
