We can't save the invoice right now when trying to create invoice of an order

[skashish]

Preconditions

1. operating system - Debian 8.9
2. php 7.0 Mysql 5.6
3. Magento 2.1.1 CE

Steps to reproduce

1. Place an order.
2. Go to Admin -> Sales -> Order
3. Select that order -> Click Invoice -> Submit Invoice

Expected result

Invoice is generated.

Actual result

We can't save the invoice right now.

Things I tried to solve the issue:

As mentioned #5324 I tried to add the column base_grand_total into the table sales_invoice_grid, but it was already present. I even added a value into it from database and it become visible on Admin Panel.

I looked into var/logs/* for some error logs, but didn't find anything related whatsoever.

Hi, @skashish, please, provide details about used payment method.

How did you place the order without any payment method?

Sorry for last comment.

In my payment methods, Check/Money order is enabled.

I've checked on Magento 2.1.7 CE with different payment methods, all works as expected, the invoices have been created successfully.

Please, upgrade your instance to the latest version and check again.

@joni-jones

is there any other way.
Mine is a very complex website.

I do not see any other way to get all fixes beginning with 2.1.1 release without updating your instance to the latest version. From version to version we fix different issues and release patch versions instead only minor releases. This approach provides more easy updates for the merchants.
