Everytime I try to submit sales invoice, Error info occurred: pymysql.err.IntegrityError: (1048, “Column ‘outstanding_amount’ cannot be null”).
I have made sure that the outstanding amount in the draft is right and not amounted to 0.
Is there anything I can do to solve this problem?
I was having the same problem and then I tried to remove all of the charges applied to the invoice. Once I did this I was able to submit the invoice. Next step was to find out the problematic charge, for which I added one charge at a time and Save->Submit.
At the last found out one charge which was causing problem. I tried to change associated account head and I was able to submit the invoice along with this charge
