In GST Regime, tax is applied on Supply of Goods, so Credit Note and Debit Note should be affected in accounts for any movement of goods. Still for the ease of working, you can enter goods received immediately in SALES RETURN menu and then create SALES CREDIT NOTE by selecting sales return entries using F5, as time permits on same day. Similarly you can enter goods returned in PURCHASE RETURN menu and then create PURCHASE DEBIT NOTE by selecting purchase return entries using F5, as time permits on same day or so.
SALES REPLACEMENT OLD, SALES REPLACEMENT GST, PURCHASE REPLACEMENT are not to be used in GST regime. Still the options are available as GST composition clients may do such transactions among them. If both customer and supplier are in composition or unregistered, these options can be used. Generally UNISOLVE clients are registered under GST regular (not composition) option, so a message is displayed that these transactions are not proper under GST regime whenever you press F5 in sales invoice or select these transactions from adjustments menu.
GSTN requires invoice reference to be posted in sales return/purchase return entries. Please read following article
