Access via 'NULL' object reference not possible

Former Member — Tue, 17 Nov 2009 06:42:56 GMT

Hi,

I'm trying to pass parameter in object CL_GOS_MANAGER. This is my coding.

data : cocode(3) type c,

docno(10) type c,

fiscal(4) type c,

temp(20) type c.

cocode = ORGANISATIONS(3).

docno = CORR_DOC(10).

fiscal = CORR_DOC+13(4).

concatenate cocode ' ' docno fiscal into temp.

DATA: LO_MANAGER TYPE REF TO CL_GOS_MANAGER,

LA_OBJ TYPE BORIDENT.

LA_OBJ-OBJTYPE = 'BUS2021'.

LA_OBJ-OBJKEY = temp.

call method LO_MANAGER->set_id_of_published_object

exporting is_object = la_obj.

if sy-subrc = 0.

endif.

But I always get ABAP dump message Access via 'NULL' object reference not possible.

Anyone can help me ?

Thanks,

Melissa

HI,

Here's is the whole scenario I'm facing.

When I open FIBLFFP (payment request) -> I create object. This is in order to be able attach file

(Method CREATE_FREEFORM_PAYMENT)

DATA :  LA_OBJ TYPE BORIDENT.

         LA_OBJ-OBJTYPE = 'BUS2021'.
         LA_OBJ-OBJKEY = '0000000000'.   * This is an initial document number, because the correct doc no not yet generated

         CREATE OBJECT CL_GOS_MANAGER
            EXPORTING
               IS_OBJECT = LA_OBJ
               IP_NO_COMMIT = SPACE
            EXCEPTIONS
               OTHERS = 1.

When I want to save my payment request, then only I can get the document number generated by SAP.

I need to pass the the combination company code + doc no + fiscal year to the object key of object CL_GOS_MANAGER I've created earlier.

(EXIT_SAPL2021_002)
DATA : cocode(3) TYPE c,
             docno(10) TYPE c,
             fiscal(4) TYPE c,
             temp(20) TYPE c,
             la_obj TYPE borident.

              cocode = organisations(3).
              docno = corr_doc(10).
              fiscal = corr_doc+13(4).
              CONCATENATE cocode ' ' docno fiscal INTO temp.

               la_obj-objtype = 'BUS2021'.
               la_obj-objkey = temp.

               CALL METHOD lo_manager->set_id_of_published_object
                 EXPORTING
                   is_object        = la_obj.

Then I get the error message.

Any suggestion so that I could have the attached file linked to the new document created ?

Thanks,

Melissa

Hi Melissa,

Is it dumping at the below statement.

call method LO_MANAGER->set_id_of_published_object

exporting is_object = la_obj.

Check if there is some value in LO_MANAGER, before this statement is called, in debugging mode.

Are you freeing or clearing it before ?

Hi All,

I solved it by my own.

I need to define the variable in global parameter that both of the exit and function module can recognized.

Thanks for your help.
