ERPNext-Frepple Enhanced Integration

Frepple integration for Frappe web framework

Frepple Custom App built based on Frepple Advanced Planning and Scheduling software. It was built to integrate with ERPNext, act as a connector (middle station) that allow bidirectional data transfer between Frepple software and ERPNext. It is also used to map the data type between Frepple software and ERPNext since both software do not use the same data structure and format. Refer to the Wiki section in this repository to view the data mapping in this custom app.

The App Contains

1. All necessary Frepple software menus for production planning process.

2. Import data from ERPNext to Frepple custom app with few clicks.

3. Export data from Frepple custom app to Frepple software with few clicks.

4. Generate the plan in Frepple custom app itself, with configurable constraints.

5. Import manufacturing orders, purchase orders and distribution orders from Frepple software to ERPNext.

6. Embed Frepple page into ERPNext user interface using iframe. Access the frepple screens through Frepple Custom Page.

7. Generate work orders and purchase orders in ERPNext based on the result from Frepple.

8. Delete all or selected data from Frepple Custom App with few clicks. This enable an easy way to import new plan elements and results.

9. Sync the status of work orders and purchase orders between ERPNext and Frepple.

Installation

Prerequisite

1. Installed Frepple software and successfully launched it on the localhost. Refer to this document for installing Frepple software.
2. Installed ERPNext and successfully launched it on the localhost.

Important Note:

There are three main conditions when we come to Frepple custom app installation. These conditions are described as follow:

• If you still have not installed ERPNext in your PC:
  • Skip the below installation and refer to this github repository to install ERPNext with Frepple integration app at once.
• If you already have installed ERPNext which has the old version of ERPNext-Frepple integration, you will need to:
  • First, update ERPNext files described in section I. Update ERPNext files.
  • Second, update Frepple custom app into the new version by following the instruction in section III. Update Frepple custom app.
• If you already have a running instance of ERPNext that does not have the Frepple integrated app, you will need to:
  • First, update ERPNext files described in section I. Update ERPNext files.
  • Second, install the new Frepple custom app by following the steps illustrated in section II. Install the new Frepple custom app into ERPNext.

I. Update ERPNext files

This is an important step where some of ERPNext files must be updated to accumodate the new version of Frepple custom app. To uodate these files, follow the instructions below:

1. Create a new folder.

2. Open a Powershell terminal, navigate to the newly created folder.

3. Clone this repo:

   git clone https://github.com/msf4-0/ERPNext-Update-Files.git

4. Navigate to the cloned folder:

   cd ERPNext-Update-Files

5. Open the following text file Execution_Commands.txt and run all the commands one-by-one to ensure all files are copied into their destination.

6. After all files have been copied, login to <project_name>-erpnext-python-1 container. Use the following command to login into this container as a root user:

   docker exec -it --user root <project_name>-erpnext-python-1 /bin/bash

• For example, docker exec -it --user root project1-erpnext-python-1 /bin/bash.

7. Once you login in into <project_name>-erpnext-python-1 container, by default, you will be in ~:/home/frappe/frappe-bench/sites directory. Navigate out to ~:/home/frappe/frappe-bench directory by typing:

   cd ...

8. Update the new files into the system by running this command:

   bench --site <site_name> migrate

• For example, bench --site custom-erpnext-nginx migrate.

9. After the process Compiling Python files... is finished, you will be back in the ~:/home/frappe/frappe-bench directory. This means the bench migrate process is completed. To exit from <project_name>-erpnext-python-1 container run:

   exit

II. Install the new Frepple custom app into ERPNext

1. Navigate to the bench directory by loging to <project_name>-erpnext-python-1 container. Run the folloing command:

   docker exec -it --user root <project_name>-erpnext-python-1 /bin/bash

• For example, docker exec -it --user root project1-erpnext-python-1 /bin/bash

2. By default, you will be in ~:/home/frappe/frappe-bench/sites directory. Navigate out to ~:/home/frappe/frappe-bench directory by typing:

   cd ..

3. Run the following command:

   bench get-app frepple https://github.com/msf4-0/ERPNext-Frepple-Enhanced-Integration.git

4. Install the app onto your site.

   bench --site <your.site.name> install-app frepple

• For example, bench --site custom-erpnext-nginx install-app frepple

5. Run bench start:

   bench start

III. Update Frepple custom app

The following steps are only applicable if you have installed ERPNext with the previous Frepple integrated app. Please skip this section if you already done both, I. Update ERPNext files and II. Install the new Frepple custom app into ERPNext.

1. Create a new folder.

2. Open a Powershell terminal, navigate to the newly created folder.

3. Clone this repo:

   git clone https://github.com/msf4-0/ERPNext-Frepple-Enhanced-Integration.git

4. Navigate to the cloned folder:

   cd ERPNext-Frepple-Enhanced-Integration

5. Open the following text file Frepple_Execution_Commands.txt and run the two commands one-by-one to ensure both files are copied into their destination.

6. Login to <project_name>-erpnext-python-1 container. Use the following command to login into this container as a root user:

   docker exec -it --user root <project_name>-erpnext-python-1 /bin/bash

• For example, docker exec -it --user root project1-erpnext-python-1 /bin/bash.

7. Once you login in into <project_name>-erpnext-python-1 container, by default, you will be in ~:/home/frappe/frappe-bench/sites directory. Navigate out to ~:/home/frappe/frappe-bench directory by typing:

   cd ...

8. Update the new app into the system by running this command:

   bench --site <site_name> migrate

• For example, bench --site custom-erpnext-nginx migrate.

9. After the process Compiling Python files... is finished, you will be back in the ~:/home/frappe/frappe-bench directory. This means the bench migrate process is completed. To exit from <project_name>-erpnext-python-1 container run:

   exit

Frepple settings configuration

Before starting using Frepple custom app, you are required to set up certain information to enable the integration between ERPNext and Frepple. Go to Settings > Frepple Settings.

• Authentication header:

The Bearer web token key that required for REST API request. The key can be found in Frepple Software, under Help > REST API Help.
