Why did a 'transaction could not be locked' error appear when exporting a commitment change order to QuickBooks®?

Issue 

When attempting to export a commitment change order from Procore to QuickBooks® with the ERP Integrations tool, an error message appeared saying the item was in use and the transaction could not be locked. 

• QuickBooks® Error Message:
  
  There was an error adding, modifying or deleting [XXXXXX-XXXXXXXXXXX] because it is already in use.
  The transaction could not be locked.
  
  Note: In the example above, [XXXXXX-XXXXXXXXXXX] denotes the unique identification number for the purchase order. 
   
• Cause:
  
  The export from Procore to QuickBooks® failed because the Purchase Order window was open in QuickBooks®.
