How to know what component call it?

Question

Dear experts!
   I have a problem as following: Both component BT111H_OPPT (opportunity) and BT115H_SLSO (Sales contract) call component GS_CM (Attachments) as a assignment block. In component GS_CM, the attribute FILENAME of context node VDOCUMENT has two set of value, type dropdown list, for example Droplist_01 and Droplist_02. i maintain code in method GET_V_FILENAME to supply dropdown list for attribute FILENAME. If GS_CM in component BT111H_OPPT, the attribute FILENAME only displays Droplist_01, and if GS_CM in component GT115H_SLSO, the attribute FILENAME only displays Droplist_02. So, in method GET_V_FILENAME of attribute FILENAME in component GS_CM, i must limit value depent what component (BT111H_OPPT or BT115H_SLSO) call the component GS_CM. But in method GET_V_FILENAME i do not know what component calls it. So, can i help me resolve this problem.
   Thanks for your concern!

Hi,
When the gscm object is created in each of the 2 components (ie opportunity and sales contract),by default an attribute of the GS-CM context node is set with the Bus object type of the calling object.
Bus objects are object nos assigned to each of the one order objects in the backend.
so for eg if the gscm component is called from the BT111H_OPPT,the attribute type_id of the context node CMBUSOBJ(context node in the component controller of the component GS_CM is set with the bus object type of opportunity ie 'BUS2000111'.
and when it is called from the BT115H_SLSO component,the type_id is set with the value 'BUS2000121'.
So in your get v method,read this attribute value of the context node  CMBUSOBJ of the comp controller .
But you cannot directly read the comp contoller attribute in the get_v of ur attribute filename.Creat an atttribute in the VDOCUMENT context node impl class.Now in the Do prepare Output of your view impl(lets say lv_bus_object),set the value of this attribute using something like this:
lr_comp_controller?=me->comp_controller;
ie-> lv_bus_obj= comp_controller->typed_context->CMBUSOBJ->type_id .
if the lv_bus_obj = 'BUS2000111',then calling component is  BT111H_OPPT
and if  lv_bus_obj = 'BUS2000121' then calling comp is BT115H_SLSO
In the get_v_filename ,you can do the coding by readin this attribute directly ie
u can say: if lv_bus_obj= 'BUS2000111 then use this value,else this.
