Summary
Learn how to fix the ‘Excl Amount’ field value on the Importation Split screen immediately reverting to zero (0.00) when tabbing away from the field, in Sage 200 Evolution.
Description
This article discusses how to fix the following issue when capturing transaction lines on the GRV/Supplier Invoice:
1. The user captures an amount on the Excl Amount and then tabs away from the field.

2. Immediately the Excl Amount field value returns to zero (0.00).

Resolution
Consider the following explanation that works according to the design of Evolution:
In this case, a 100% Tax Type is used on the same transaction line.

A 100% Tax Type means the total transaction line value can only be included/incorporated in the transaction line Tax value.
Therefore, Evolution is forced to change the captured Excl Amount value back to zero when tabbing away from the field.
