Thank you for your question. I'd like to gather some more information to better understand your situation,@AUmfg.
Based on the default column setup in QuickBooks Online for estimates, sales orders, and invoices, the available columns typically include Service Date, Product/Service, SKU, Description, Quantity, Rate, and Amount. Activity is not a standard column label in those transactions.
To assist you further, could you please provide more details or, if possible, a screenshot showing the specific section where you see the Activity column label? This will help me better understand the context and provide you with accurate guidance on how to modify the column label to Part Number as you mentioned.
Thank you, and I look forward to your response.
