@Mr.Manish Singh. At this stage, two problems can be anticipated. One is appropriation of income for taxation purposes and carry forward of losses particularly if the arrangement is of long term. If there is a SPV, these problems will not arise because they will be off the balance sheet of the company & partnership..
However, in case of a company and a partnership, the income against an arrangement/agreement will have to shown as "Income from other sources". This will give an opportunity to the Assessing Officer to meddle further deep in the agreement/arrangement to assess whether the income shown is correct or not. This will cause hardships to the assessee. Further, will the AO allow to set-off the losses against the agreement/arrangement cannot be said in advance because he may not accept the agreement as extention of the same business/company.
