How to fix this error?

Change your entry.
The following points must be taken into consideration for subsequent
settlement:
Allowed calculation rules:
A - Percentage, for example, 3%
B - Fixed amount, for example, 100 EUR
C - Quantity, for example, 1 EUR for each piece
D - Gross weight, for example, 1 EUR for each ton
E - Net weight, for example, 1 EUR for each kg
F - Volume, for example, 1 EUR for each litre
L - Points (only allowed in Purchasing), for example, 0,01 EUR for 1
point
By choosing calculation rules D, E, F, L you are telling the system
that it can convert the relevant units, if necessary, without a
material.
In subsequent settlement materials are currently not carried as a data
retention level. For example, you can generally no longer convert a
bottle to a drinks list in settlement. To do this, the material would
have to be known - in other words, whether it refers to bottles of beer
or mineral water etc. A conversion could no longer be carried out for a
condition of 3% on all drinks.
