class could not be found error

Former Member — Tue, 21 Nov 2006 17:08:05 GMT

Hi All,

I'm trying to implement the BADI NETW_USER_FIELDS_F4 to be able to define a search help for an user field in transaction CJ20N.

The Badi implemenation, class are active. But upon executing the F4 help, the program dumps with the following description

" CREATE OBJECT: Class "\CLASS=CL_EX_NETW_USER_FIELDS_F4" could not be found. "

The dump is from the get_instance method at the following line -

CREATE OBJECT exit TYPE (abs_type_classname).

The parameter 'exit' which is a type ref to object returns "illegal reference". Not sure where am I making the mistake.

Pls note that the dump is even before the program reaches the BADI implementation, so the code I have in the AT_F4 method is not of significance I suppose.

Any help would be highly appreciated.

Thanks

Uday

I already tried those threads. But this time, the program is still at the instance creation step when it dumps.

Dumps at this step

call method cl_exithandler=>get_instance

exporting

exit_name = 'NETW_USER_FIELDS_F4'

null_instance_accepted = const-flg_yes

changing

instance = ref_netw_f4.

This is later !!!

if not ref_netw_f4 is initial.

call method ref_netw_f4->at_f4

exporting i_caufvd = caufvd

i_afvgd = afvgd

i_user_field = user_field

importing e_value = return_value.

SE38 -> LCONWF31

Noticed in debugging the data declaration

ref_netw_f4 type ref to if_ex_netw_user_fields_f4

returns the value "illegal reference". Not sure why this is the case.

Try to see the <a href="https://websmp102.sap-ag.de/~form/handler?_APP=01100107900000000342&_EVENT=REDIR&_NNUM=865187">note 865187</a>, it could be helpful for you.

If you can't see the note, this is an extract:

Summary

Symptom

You have implemented BAdI NETW_USER_FIELDS_F4 to provide F4 help for Network Activity User Fields.

You go to transaction CJ20N or CN22 and press 'F4' on a Network Activity User Field. Short Dump occurs because of

Runtime errors CREATE_OBJECT_CLASS_NOT_FOUND

Exception CX_SY_CREATE_OBJECT_ERROR

You go to transaction SE18 and do a Check(CTRL + F2) on BAdI NETW_USER_FIELDS_F4. The system gives a Message:

Message no. ENHANCEMENT367

"BAdI class CL_EX_NETW_USER_FIELDS_F4 does not exist."

Other terms

BAdI NETW_USER_FIELDS_F4, BAdI class CL_EX_NETW_USER_FIELDS_F4 does not exist, F4 help for Network Activity User Fields

Reason and Prerequisites

This is because BAdI Adapter Class CL_EX_NETW_USER_FIELDS_F4 is not present.

Solution

You will have to create the exit class by performing the following steps:

1. Go to Transaction SE18.

2. Enter BAdI Definition name NETW_USER_FIELDS_F4.

3. Go to menu path Utilities->Regeneration.

Now the BAdI class CL_EX_NETW_USER_FIELDS_F4 should get generated.
