Hi HF,
"Barcode" field is already there in the item master, you can pull items based on "Barcode" in Delivery Note and Sales Invoice. The feature is hidden by default, you can activate it from Setup --> Disable Features.
Currently, Barcode field is not exists in Stock Entry, we will add it soon, so that users can pull item based on barcode while issue or transfer items from one warehouse to another.
You can hide Rate column for a particular Role, by modifying permlevel of the Rate field and assigning different access restriction against that permlevel. But currently there is a bug in the system, column is not hiding based on permlevel, we will fix this soon. It has been discussed in detail on a previous thread (
https://groups.google.com/forum/?fromgroups=#!searchin/erpnext-user-forum/permission/erpnext-user-forum/nKDgysdrwpk/MXzp4qGxBQgJ).
About Rate validation, it is difficult to implement by custom code by yourself. Please create an issue in Github, we will try to add the feature in the future.
Thanks,
Nabin Hait
I have added a custom field (barcode) for Items, and I need this field to appear in the stock_entry_items with the barcode of the item selected, also I need to let the field item rate hidden for special users and appears for another users.
Also if the rate is changed by users to more than 20% of the standard rate the system does not accept.
