India GST sales update and after sales update process understanding

Hi,

Same account hits multiple times in GL after sales update process. Need to understand sales update process and after sales update process for India GST.

P0911 entries after sales update:    

Account	Amount	Acct Desc.	DMAAI
621.5015	1,500.00-	Wholesale Sales Revenue	4230
621.602	750	Prime Cost of Goods	4220
621.1411	750.00-	Inventory	4240
621.5015	90.00-	Wholesale Sales Revenue
621.5015	90.00-	Wholesale Sales Revenue
621.5015	90	Wholesale Sales Revenue
699.1000.CGST	90.00-	Central Goods & Service Tax	GST Permanent Account
621.5015	90	Wholesale Sales Revenue
699.1001.SGST	90.00-	State Goods & Services Tax	GST Permanent Account

Why 621.5015 is called multiple times?
