Tribunal   held that the assessee had adopted the methodology for revenue recognition for both the projects adopting the percentage completion method but the Principal Commissioner had only disputed the revenue recognition of the one  project.  During the assessment proceedings, the Assessing Officer had made proper, sufficient and adequate enquiry on the issues including the issue of revenue recognition of the assessee following the percentage completion method and project-wise revenue recognition. Therefore, it was not a case of no enquiry, inadequate enquiry or insufficient enquiry. The assessment order was not erroneous or prejudicial to the interests of the Revenue.( AY.2013-14)
