How to create a relationship between 2 GOS objects

milan_dobias — Fri, 27 Feb 2009 05:28:45 GMT

Hi all,

I have a small problem how to create a link between 2 GOS (businnes objects) .

I have 2 different business objects ( Z* type, for example class Z1 and Z2) defined using SWO1, and I want to create link between instances of 2 GOS objects.

I try to use FM 'BINARY_RELATION_CREATE' ,

fill parameters OBJ_ROLEA , OBJ_ROLEB ,

but I know how to fill parameter RELATIONTYPE.

All the time I got a message RL 301 (Role type '&1' is not assigned object type '&2').

Should I make some customization (and how ) for roles of object Z1 and Z2 ?

Or should I use any general relationtype ?

Can somebody helo me to explain, how to make customization , or any link, example ?

Thanks in advance

Milan Dobias

hi,

1. check table: SGOSATTR Entry:Name SRELATIONS if the GOS is allowed

2. by creating the GOS:

coding snip

   CALL METHOD cl_binary_relation=>create_link
      EXPORTING
        is_object_a = lo_is_object_a
        is_object_b = lo_is_object_b
        ip_reltype  = 'ATTA'.

ATTA > attach to gos

best reg robert

Thanks for Your answer, but main problem is what relation type use to create link between 2 common objects.

Your solution (use class CL_BINARY_RELATION) returns the same error message, because this class is used in FM BINARY_RELATION_CREATE.

In the end I found that solution is to use as relationtype (ORBRELTYP-RELTYPE = 'ASGN').

CALL FUNCTION 'BINARY_RELATION_CREATE'

EXPORTING

obj_rolea = obj_a

obj_roleb = obj_b

relationtype = 'ASGN'

EXCEPTIONS

no_model = 1

internal_error = 2

unknown = 3

OTHERS = 4.

It seems to work and on both objects (A and B) I can see link (relation).

Best regards,

Hi Milan,

Could you tell me how to find out what should be the relation type for other type of objects? I also need this information
