Your efforts in attaching a screenshot is appreciated, bena. Issues with creating customer statements can be challenging, especially when timely communication is vital for cash flow and your business's financial health. Together, let's explore an alternative so you can create customer statements effectively. 

Since you're only creating statements for approximately 50 customers but encountered this alert message, I'd recommend choosing the Multiple Customers selection instead of the All Customers option. This approach lets you select specific customers, potentially avoiding data issues affecting this process.

However, if you continue to receive the same alert message, I'd suggest performing some diagnostic procedures to resolve this unexpected behavior. These steps can help us identify the root cause of the issue and implement an effective solution. 

Here's how:  

1. Click the Window tab, then select Close All.
2. Go to the File menu, and then hit Utilities.
3. Choose Verify Data. If you see: 
   • QuickBooks detected no problems with your data: The data is clean. An error message: We can search for it on our QuickBooks Desktop support site on how to fix it. 
   • Your data has lost integrity: Data dais detected. Rebuild your data to fix it.  

Then, we can Rebuild your company file data to ensure we can completely remove any problems. If the issue persists, we can use the QuickBooks Desktop Tool Hub to fix common QuickBooks Desktop issues.  

Additionally, you have the option to create statements for each customer individually for now. This approach tailors information for each customer's needs, ensuring they receive accurate and relevant transaction details.
