Table Maintenance - Error Handling Explained

In any exit method, DATA, UPDATE or META, you can (and should) implement error handling and show an error message to the user. You can utilize the changing parameter CT_MESSAGES to show messages.

Visual Types

Currently, “modal” and “toast” visual types are available 

• /nly/cl_table_rest_v3=>co_visu_type_modal to show a popup with ok button

• /nly/cl_table_rest_v3=>co_visu_type_toast to show a dialog without user interaction

Message Types

Furthermore, you can use the following message types to indicate the severity of the message:

• /nly/cl_table_rest_v3=>co_msg_type_info (no colour)
• /nly/cl_table_rest_v3=>co_msg_type_success (green)
• /nly/cl_table_rest_v3=>co_msg_type_warning (yellow)
• /nly/cl_table_rest_v3=>co_msg_type_error (red)

CT_MESSAGES Explained

The messages are passed using the CT_MESSAGES table. You can find CT_MESSAGES parameters in the table below.

Code example

You can find an example of the code below

DATA:ls_message TYPE /nly/ts_message.
ls_message = VALUE #( hdr = 'Title'
                      msg = 'Message'
                      type = /nly/cl_table_rest_v3=>co_msg_type_error 
                      visu_type = /nly/cl_table_rest_v3=>co_visu_type_modal
                       ) .
 APPEND ls_message TO ct_messages.

You can use this approach to add a message to your DATA exit, as shown below. In this example, no data should be shown in November. Data processing will be skipped using the E_SKIP parameter and an error message will be shown to the user.

IF i_step = 1.
  IF sy-datum+4(2) = '11'.

   e_skip = 'X'.
   ct_messages = VALUE #( BASE ct_messages
                        ( type = /nly/cl_table_rest_v3=>co_msg_type_error
                          visu_type = /nly/cl_table_rest_v3=>co_visu_type_toast
                          hdr = 'Planning not allowed'
                          msg = 'Planning round is over, no values will be displayed'
                          ).
