There are two possibilities: 

Create New Price List 

This option is available only if you select an LPG in the list of LPGs.

1. From the list of Live Price Grids (LPGs), select the LPG to be converted to a Price List.
2. Click the 'Convert to Price List'  icon.
3. A copy of the LPG will appear in the list of Price Lists where it can be used as any other Price List. 

Append LPG Items to Existing Price List 

This option is available only if you run the conversion from within an LPG.

1. Open a particular LPG. 
2. Select products that you want to include in the Price List. If you make no selection, the new Price List will contain all the products from the LPG.
3. Click the 'Convert to Pricelist'  icon. A field-mapping dialog opens:
   
   • Select the target Price List from a drop-down menu.
   • Decide if you want to overwrite existing Price List items. If this option is not enabled, the LPG items will be appended to the Price List.
   • Perform the field mapping. The mapping table will only contain rows if the source LPG has mapped output columns (i.e., any attributeXX fields) – otherwise, the table will be empty.
4. Confirm.

The new Price List inherits the same preferences (columns visibility, order etc.) as the original LPG.

If filters are set in the LPG, only the filtered set of rows will be converted to the Price List.
