# Moisture Sensitive Level Configuration

This section covers the configuration required to use Moisture Sensitive Level handling in Critical Manufacturing MES.

## Initial Setup

This exercise uses the out-of-the-box **Moisture Sensitivity Level** data.

The configuration starts in the MSL table shown in the previous section and continues with the values defined on the **Product**, **Product Manufacturer**, and **Material** records.

The supporting master data workbook for this tutorial is available here: [Moisture Sensitive Level Master Data](masterdata/moisture_sensitive_level.xlsx).

## Configure MSL on the Product

To enable MSL handling, configure the following properties on the **Product**:

- **Moisture Sensitivity Level** - select the appropriate MSL for the product.
- **Floor Life** - the duration for the selected MSL.
- **Floor Life Unit Of Time** - the corresponding unit, such as hours, days, weeks, or years.

The system automatically fills the **Floor Life** and **Floor Life Unit Of Time** fields based on the selected MSL.

These properties are also available when configuring products for Material Logistics. For more information about the entity itself, see [[user-guide-create-product]].

## Configure MSL on the Product Manufacturer

You can also configure MSL for **Product Manufacturers**. This is useful when a manufacturer-specific definition should be applied during material creation or registration.

For more details on this area, see [[user-guide-manage-product-manufacturers]].

## Priority of MSL Values

When MSL is defined in multiple places, the following hierarchy applies:

1. The MSL defined on the **Material** takes priority.
2. If no material-level value exists, the **Product** MSL is used.
3. If neither of the above exists, the **Product Manufacturer** MSL is used.

## Create Materials with MSL

When a **Product** already has a **Moisture Sensitivity Level** defined, the **Material** automatically inherits the corresponding floor life information during creation.

You can still change the MSL during material creation if needed.

If **Remaining Floor Life** is defined, the system sets the **Floor Life Counter State** to **Stopped** by default.
