For a Catch weight item with advanced management warehousing enabled, it's not possible to modify the minimum and the maximum quantity of the Catch Weight as these values are linked to different transactions.

The only possible way to modify these values is by applying the below mentionned steps :

• Do the ajustement OUT of the stock of the item
• If the item contains BOM or Formula, need to delete the BOM/Formula version
• Apply the modification of the minimum and the maximum quantity of the Catch Weight
• If the item contains BOM or Formula, create the BOM/Formula version again
• Do the ajustement IN of the stock of the item

This process is cumbersome for the business which needs the coordination between the logistic team and the data owner and also it impacts the sales and the production of the concerned item.

The suggestion is to have an automatized process to run these steps by a data management import (to import the value) followed by a batch job.
