Source Code - Item Balance, Age and Value by Warehouse(s) - Pivot Table

Recently I paid a developer to build a report like below… Can I post the source here?


My vote is yes - contributions are welcome and encouraged I would venture!

But uploads are limited to screenshot graphics files that are typically malware-free.

So if your Pivot Table is in Excel spreadsheet form I can’t say how to post that here since those lack source code form, say to copy and paste here?

If you have made changes to the code, then send a Pull request on GitHub - frappe/erpnext: Free and Open Source Enterprise Resource Planning (ERP) . The maintainers will review the code, if required they may suggest some changes, and if it is good they’ll merge it.

So please ask your developer to send a Pull Request.

thank you

Thanks for the code, but here it will be lost in forum, ideal place for getting it merged in the frappe code is github.

please help me how to do that!

I set up a developer server in developer mode, then create this report then how can I merge it with GitHub ?

First step is to register on
Then I suggest you understand the github workflow . There are a lot of tutorials for this online.

Then fork the erpnext or frappe project on github, add your changes to it and send a Pull Request. Here is a guideline for contributing in erpnext.

Let me know if you get stuck anywhere.

P.S. The advantage of going through all this is that it will be easier to track and fix in future and also as a bonus will have your name as a contributor to frappe and erpnext.
