Hello M. Hasan,
AX can only do simple consolidations. Consolidations according to the equity method and for joint ventures are not or not fully supported. For those consolidation scenarios you can either make numerous system adjustments or you need to make use of specialized consolidation software.
Maybe the consolidation features in Management Reporter are an option for you. Yet, also when using the Management Reporter you will need to do many manual consolidation steps outside and Import them e.g. through Excel.
Unfortunately, financial consolidations is one of the "weakpoints" of AX :-(
