Batch Fetching problem in purchase invoice

I want to fetch batch no while creating purchase invoice from purchase receipt .
Any one plz help me

Hi

You might be able to add the batch number by customizing the Purchase Invoice Item table. Customizing forms is covered here: https://docs.erpnext.com/docs/v13/user/manual/en/customize-erpnext/customize-form

Adding a link field is documented here: https://docs.erpnext.com/docs/v12/user/manual/en/customize-erpnext/articles/creating-custom-link-field

Whenever making changes it is is best to have a backup in place or a duplicate instance of your ERPNext to test with.

I want to fetch batch number from purchase receipt to purchase invoice without the batch selection process.

Try In the Purchase Invoice , customize Purchase Invoice Item child form , add a row with a Batch Number link to Purchase Receipt Item Supplied.
