BOPF: Create instance in another object

[former_member249109]

Hi,

I have two independent BOs, which at the moment are not related to each other (there is no association defined), let's call them First and Second.

If I try to create an instance in Second through a simple ABAP program, I can perfectly do something like this and the entry in the database will be created:

 transaction_manager = 
   /bobf/cl_tra_trans_mgr_factory=>get_transaction_manager( ).


service_manager =
      /bobf/cl_tra_serv_mgr_factory=>get_service_manager( 
           zif_i_secondnode_c=>sc_bo_key ).


object_configuration =
      /bobf/cl_frw_factory=>get_configuration(
        zif_i_secondnode_c=>sc_bo_key ).
        
data: second_node type ref to z_combined_structure.  

second_node->key = /bobf/cl_frw_factory=>get_new_key( ).
second_node->concept = 'C0017'.
second_node->date = '20181017'.
second_node->description = 'brief description for this item'.
second_node->cost = '9.00'.

APPEND VALUE /bobf/s_frw_modification(
              node        = zif_i_secondnode_c=>sc_node-zsecond_node
              change_mode    = /bobf/if_frw_c=>sc_modify_create
              key            = second_node->key
              data           = second_node  )  TO mod_table.
              
service_manager->modify( 
EXPORTING it_modification = mod_table                 
IMPORTING eo_change = DATA(change_object)                 
          eo_message      = DATA(messages) ).   


IF change_object->has_failed_changes( ) = abap_false.
  
  "This doesnt give any error when running from an ABAP program
  "But from an action from FIRST_NODE, I get a dump
  transaction_manager->save( 
   IMPORTING ev_rejected =  DATA(was_rejected)
             eo_message  =  messages   ).
ENDIF.

However, running this same code in a BOPF action from my object First, I get a runtime error.

How can I achieve such a result? Storing instances in BOs inside the Action for another BO.

Did you check, what happens if you dont do save-call from transactionmanager in action of first node?

How is the bopf action called? There should be the save-call and not inside the action.

Hi Christian,

Thanks for your reply!

If I don't do the save call, nothing happens. The entry is not saved in second_node.

The action is called CLOSE, I didn't understand your last sentece, did you mean the transaction_manager->save( ) call should not happen inside the CLOSE action from FIRST_NODE?

[cwolter90]

My question was mistakable...

Where is the close-action called? Do you call the action yourself with a servicemanager or is it called by any framework? I guess the save-call should happen after the action is called.

I tested the action in BOBT transaction.

Finally I got it working,

The modification had to be done using the transaction manager rather than the service manager, like this:

transaction_manager->modify(EXPORTING it_modification = 
                       VALUE #( (node = zif_i_secondnode_c=>sc_node-zsecond_node
                                 change_mode = /bobf/if_frw_c=>sc_modify_create
                                 data = second_node) )

There was no need to call the SAVE change from the transaction manager either
