hi ,
1 create context in ur component controller and a context attribute say attr under it
2 map it to both of ur Main and Second View , just drag and drop the context node to the
Context in both the views
3 read the attribute ( this is binded to ur input field ) in the main view
Go to control wizard ( Control +f7) , select the radio button read context node / attribute
Select the node and read the attribute using get_attribute method
4 now do component usage for ALV
i)     In the component controller , create a context node .This context node will be used to generate the ALV grid table. The context attributes inside the context node would refer to the columns in the table .give dictionary structure
ii)     Double click on the component and define usage for SALV_WD_TABLE
5 write this piece of code in WD DOINIT of ur 2nd view
DATA :lv_ vbeln1 type string .
Lv_Vbeln1 = wd_comp_controller->gv_vbeln .
  Data: itab_vbap type standard table of vbap .
*select data from data base table
select * from vbap
into corresponding fields of table itab_vbap where vbeln EQ lv_vbeln1.
* bind data to context used by ALV
  context_node = wd_context->get_child_node ( name = 'ALV_TABLE').
  context_node->BIND_table( itab_vbap).
