内部连接仅返回一个表而不是两个表的结果

Question

SELECT InvoiceNo as [Invoice No],
       SUM(Quantity) as Quantity,
       SUM(TaxableAmt) as Taxable_Amount,
       SUM(CGSTAmt) as CGST_Amount,
       SUM(SGSTAmt) as SGST_Amount,
       SUM(Amount) as Amount 
FROM tbl_PurchaseDetails    
INNER JOIN tbl_CUSTOMERMASTER 
  ON tbl_CUSTOMERMASTER.PartyID = tbl_PurchaseDetails.PartyID     
GROUP BY tbl_PurchaseDetails.InvoiceNo
