Realized that Stock Reconcilliation tools doesnt have option as Purchase receipt that can allow zero valuation. Kindly advise how could we solve this if I need to upload for Opening Stock with zero value.
Maybe you can try to upload opening stock using Stock Entry.
As @Pawan suggested, as of now you can use Stock Entry for the purpose. Also I will request you to create a github issue to allow zero valuation rate in Stock Reconciliation form.
