# New Update in Define Item Wise Price Lists Window
**YouTube:** [New Update in Define Item Wise Price Lists Window](https://youtu.be/ZIKSVQ1Epdo)
### New Update to Display Price List
LogicERP has introduced a new column in “Define Item Wise Price Lists” window i.e., “**Markdown is Zero**.” You will notice two new options in it:
**1. Return Base Rate**: To return the base rate of the item.
**2. Return Zero Rate**: To return Sale Rate zero, when item not defined in the Price List Group
When you select the Return Zero Rate option, you will not be able to generate the bill for the items which are not in Price List Group. You will get the following message
As you can see that the Sale Rate of No.-4 Item is 0. It’s because it does not belong to any Price List Group. So the message appears on the screen, “Enter Rate.” It will notify you that to continue further, you need to include the item in Price List group.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://kb.logicerp.com/logic-erp-version-release-notes/december-2018/billing/new-update-in-define-item-wise-price-lists-window.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
