Error Advanced Payment on sales invoice

Hi i have got this message when try to submit a sales invoice with advanced payment:

I dont know what mean this message, someone can help me?

Say Umair may recognize the biz case here?

Here’s another case Payment Entry has been modified after you pulled it

Here’s the actual code to ponder erpnext/utils.py at develop · frappe/erpnext · GitHub

and the code comments if they are accurate:

	check if there is already a voucher reference
	check if amount is same
	check if jv is submitted

hope this helps
