I have created pull request Added Actual Batch Qty for item in DN & SI by sbkolate · Pull Request #2942 · frappe/erpnext · GitHub,
which adds Actual Batch Qty for item in DN & SI,
I have created one custom field. After selecting batch in DN it shows Actual Qty of item for that Batch.
This works successfully.
After that I am working on next issue. Batch should be sorted based on expiry_date, instead of posting date.
Batch Issue - Piling of list · Issue #2592 · frappe/erpnext · GitHub
With small modification in get_batch_no query we can sort batch with expiry_date.
In mean time, I found better way for showing batch quantity.
We can show available batch quantity and expiry_date in drop down list with small change in get_batch_no query
I have attached screen shot for batch with sorted based on expiry_date, and batch with actual qty.
Please give advice which way is more helpful and correct.
