How to fix this error?

This is where you use the parameters days' supply, receipt days' supply
1, and receipt days' supply 2 to define under what circumstances
materials are indicated by red, yellow, and green traffic lights in the
MRP list.
Example:
When days' supply <= 0, you want the traffic light for a material to be
red, when days' supply > 0 und <= 10 days the traffic light is to be
yellow, and when days' supply > 10 days the traffic light is to be
green.
You define the following:
,,,,,,,,,,Red,,,,Yellow,,Green
Days' supply:,,,,0,,,,10,,,,999,9

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

The standard, predefined value for the green traffic light is 999.9.
Settings for > yellow traffic light (> 10 days in the example) thus
automatically generate a green traffic light.
The setting for the receipt days' supplies is analogous to the settings
for days' supply.
The traffic light is set after the settings for all ranges of coverage
and all exception groups have been taken into consideration.
Example:
If a material has a days' supply of 12 days, a green traffic light
would be set according to the above setting. However, when an exception
of exception group 4 exists, and exception group 4 is indicated in red,
the material is thus given a red traffic light.
