HSN / SAC Code Entry for expenses

We purchase Housekkeping items, stationary items from METRO Cash & Carry. They issue TAX Invoices mentioning our GSTIN. These items being purchased are not our trading items or raw materials, but pantry items, stationery items, housekeeping items and other consumables in our office. Their invoice has 15-20 items with different HSN Codes and different GST Rates. I am claiming ITC on the above expemses

My query is, in our Purchase Register (Purchase Voucher in Tally) should we enter all the 15-20 items with HSN Codes and GST Rates ? Alternatively would it suffice with just one expense entry without any HSN Code, Please advice
