Hello,
The client has this configuration in Method of payment-Period: TOTAL

But when the journal is generated from the proposal, although the same payment date, payment method and bank account are indicated:

the lines for the same vendor are still open.

What is needed is that the payment is on a single line, but I have not been able to find what are the criteria that the proposal uses
to leave the transactions on separate lines. Someone could help me? Is there an option to always leave only one line?
I already appreciate your comments
Valeria
