Try and Catch

Former Member — Thu, 04 Oct 2007 06:30:10 GMT

Hi experts,

I am trying to catch the exception CX_SY_REF_IS_INITIAL.

The current syntax are as below :-

DATA: lr_view_manager TYPE REF TO cl_bsp_wd_view_manager

, lr_cucobdc TYPE REF TO cl_crm_ic_cucobdc_impl.

lr_view_manager ?= zl_2007_ic_tools_impl=>get_view_manager( ).

lr_cucobdc ?= lr_view_manager->get_custom_controller( 'CuCoBDC' ).

Currently the statement

lr_cucobdc ?= lr_view_manager->get_custom_controller( 'CuCoBDC' ). is pointing to nothing.

Can anyone show me how to write the codes.

Regards,

Hi Shiva,

I've tried the syntax but there are still error. Can you tell me whether this is correct?

TRY

lr_cucobdc ?= lr_view_manager->get_custom_controller( 'CuCoBDC' )

CATCH cx_sy_ref_is_initial.

ENDTRY

Thanks,

Hi Sesh,

I tried the syntax but this error pops out.

TRY.

lr_view_manager ?= zl_2007_ic_tools_impl=>get_view_manager( )

lr_cucobdc ?= lr_view_manager->get_custom_controller( 'CuCoBDC' )

CATCH CX_SY_REF_IS_INITIAL.

If sy-subrc = 0.

ENDTRY.

"out-field?=method" can only be specified once.-----

Can you please advice.

Regards,
