You can categorise the fabric prices. If you deal with a large set of fabrics then you can define the price category for each set of fabrics. And once you update the price here, it will automatically get updated in the master inventory. Having fabric prices in hand will help you in inventory management.
Go to Setup then Inventory Setup and now Fabric Price Slabs
Enter the Fabric Price Category Name and in the Price List, you can select the tailoring sub-category i.e. in which sub-category the fabric price will be applied. Now enter the fabric cost as per the tailoring sub-categories.
