Are Purchase Details Mandatory in GSTR-4?

In the case of composition dealers who are filing GSTR-4, providing information on inward supplies from the registered suppliers (excluding reverse charge supplies) is, indeed, mandatory in Table 4A. Note that this requirement was initially waived until December 2017; it was later extended until June 2018. The reason for the same was the non-access to the auto-population facility of inward supply details.
However, as there was an introduction of the auto-drafted purchases in the GST portal, composition dealers were then required to furnish such details in GSTR-4 Table 4A, starting quarters July-September 2018 onwards.
