Thanks Jyothi.
Do you know which table can we use to enhance the datasource with company code?.
I am thinking of using datasource0CO_OM_CCA_9 for my Report because this Datasource has already Company Code. But it doesn't have Plan cost.
Another Idea is to join 2 Datasource *1 and *9. However i don't know how to join them because *1 is based on fiscal Period (month) and *9 is based on date.
