Data Upload¶

In this tutorial, you will learn how to upload existing data from your local Python project into the EMS. More specifically, you will learn:

How to create a new table in the EMS with your data
How to append and upsert your data to existing tables in the EMS
How to add a table from your data pool to your data model
How to reload a data model

Prerequisites¶

To follow this tutorial, you should have already created a data pool and a data model inside your pool. If you haven't done this yet, please complete the Data Integration - Introduction tutorial first.

Tutorial¶

1. Import PyCelonis and connect to Celonis API¶

Copied!

from pycelonis import get_celonis
celonis = get_celonis(permissions=False)
from pycelonis import get_celonis
celonis = get_celonis(permissions=False)

[2024-12-02 16:11:04,736] INFO: No `base_url` given. Using environment variable 'CELONIS_URL'

[2024-12-02 16:11:04,737] INFO: No `api_token` given. Using environment variable 'CELONIS_API_TOKEN'

[2024-12-02 16:11:04,828] INFO: Initial connect successful! PyCelonis Version: 2.12.0

2. Select data pool to upload data into¶

Before we can upload data into the EMS, we first have to select a data pool, into which the data should be uploaded. Here, we use the data pool, which we created in the Data Integration - Introduction tutorial:

In [4]:

Copied!

data_pool = celonis.data_integration.get_data_pools().find("PyCelonis Tutorial Data Pool")
data_pool
data_pool = celonis.data_integration.get_data_pools().find("PyCelonis Tutorial Data Pool")
data_pool

Out[4]:

DataPool(id='be065bab-bc94-4f2e-81d3-f4df1e126e2a', name='PyCelonis Tutorial Data Pool')

With the get_tables() method, we can verify that we currently don't have any tables in the data pool:

In [5]:

Copied!

data_pool.get_tables()
data_pool.get_tables()

Out[5]:

[]

3. Upload data into the EMS¶

Data can be uploaded into Celonis in two formats: as Pandas dataframes or as Parquet files. In this tutorial, we will focus on pushing data as Pandas dataframes. If you want to push data as Parquet files, please refer to the Data Push & Export Advanced tutorial.

In this tutorial, we will use a sample dataset for the SAP Purchase-to-Pay (P2P) process, which depicts the process of procuring materials from vendors. Below, is an overview of the most important tables for this process:

Table	Description
_CEL_P2P_ACTIVITIES_EN	Activity Table
EKPO	Purchasing Document Item (i.e. Case Table)
EKKO	Purchasing Document Header
LFA1	Vendor Master Data

Let's start by importing the tables of this dataset as Pandas dataframes:

After having the dataframes in place, we can upload them into the EMS by either creating new tables in the data pool or by appending/upserting the data into existing tables of the data pool.

3.1 Create new table in the EMS¶

New tables can be created in the EMS with the create_table() method. The method takes as input arguments:

Name	Type	Description	Default
`df`	`DataFrame`	A pandas dataframe containing the data	Required
`table_name`	`str`	Name that the table in the data pool should have	Required
`drop_if_exists`	`bool`	Specifies how to handle situations when a table with the same name already exists in the data pool (True = replace existing table, False = raise error and keep existing table)	`False`

Further, we can give a column_config as input argument, which specifies the names and column types of our table. Specifying a custom column_config is especially important if we use tables with longer text values, as by default, strings are cut off after 80 characters during the data upload. For a guide on how to specify a custom column_config, refer to the Data Push & Export Advanced tutorial.

3.2 Append data to existing table in the EMS¶

We can also choose to append our data to an already existing table in our data pool with the append() method. The method takes as input arguments:

Name	Type	Description	Default
`df`	`DataFrame`	A pandas dataframe containing the data	Required

Important:
The column types and names of our dataframe must be the same as in the target table in the data pool, otherwise the append operation will fail.

Let's create a new activity table ACTIVITIES_APPEND in our data pool, to which we want to append a new dataframe:

3.3 Upsert data to existing table in the EMS¶

Lastly, we can choose to upsert our data into an already existing data pool table with the upsert() method. Upsert works similar to the append operation (i.e. it adds rows from a dataframe into a table) but replaces rows if they already exist. For this, we have to specify in keys a list of column names according to which to check for equality. If two rows have the same values in all columns specified in keys, they are marked as duplicates and replaced.

The upsert() method takes the following input arguments:

Name	Type	Description	Default
`df`	`DataFrame`	A pandas dataframe containing the data	Required
`keys`	`List[str]`	List of column names according to which to check for equality	Required

Let's create a new activity table ACTIVITIES_UPSERT in our data pool, to which we want to upsert a new dataframe:

4. Add table to a data model¶

After having uploaded our data into the data pool (either as a new table or by appending/upserting into an existing one), we can add the table into a data model.

For this, we navigate to the data model, which we created in the Data Integration - Introduction tutorial:

In [16]:

Copied!

data_model = data_pool.get_data_models().find("PyCelonis Tutorial Data Model")
data_model
data_model = data_pool.get_data_models().find("PyCelonis Tutorial Data Model")
data_model

Out[16]:

DataModel(id='68682a56-5bc4-4bfb-be4e-2e588335549c', name='PyCelonis Tutorial Data Model', pool_id='be065bab-bc94-4f2e-81d3-f4df1e126e2a')

To add a table from the data pool into the data model, we have to call the add_table() method. The method takes as input arguments:

Name	Type	Description	Default
`name`	`str`	Name of the table inside our data pool	Required
`alias`	`str`	Alias for the table, i.e. how the name should be displayed inside our data model	`None`

In [17]:

Copied!





data_model.add_table(name="ACTIVITIES", alias="ACTIVITIES")
data_model.add_table(name="EKPO", alias="EKPO")
data_model.add_table(name="EKKO", alias="EKKO")
data_model.add_table(name="LFA1", alias="LFA1")
data_model.add_table(name="ACTIVITIES", alias="ACTIVITIES")
data_model.add_table(name="EKPO", alias="EKPO")
data_model.add_table(name="EKKO", alias="EKKO")
data_model.add_table(name="LFA1", alias="LFA1")

[2024-12-02 16:11:05,769] INFO: Successfully added data model table with id 'a29074bc-240a-4bc3-b050-0b35e7f0000f' to data model

Out[17]:

DataModelTable(id='a29074bc-240a-4bc3-b050-0b35e7f0000f', data_model_id='68682a56-5bc4-4bfb-be4e-2e588335549c', name='LFA1', alias='LFA1', data_pool_id='be065bab-bc94-4f2e-81d3-f4df1e126e2a')

The method will take the table from our data pool and create a reference to it inside our data model, including all properties, such as column names and data types. To verify that the tables exist in our data model, we can call the get_tables() method:

In [18]:

Copied!

data_model.get_tables()
data_model.get_tables()

Out[18]:

[
	DataModelTable(id='4a59374a-bdd6-4a08-a036-87429391cbbf', data_model_id='68682a56-5bc4-4bfb-be4e-2e588335549c', name='EKKO', alias='EKKO', data_pool_id='be065bab-bc94-4f2e-81d3-f4df1e126e2a'),
	DataModelTable(id='e86d10ab-6636-4e36-9695-0e29b4a4f5c3', data_model_id='68682a56-5bc4-4bfb-be4e-2e588335549c', name='ACTIVITIES', alias='ACTIVITIES', data_pool_id='be065bab-bc94-4f2e-81d3-f4df1e126e2a'),
	DataModelTable(id='913addb7-aeda-4645-9508-75a183283095', data_model_id='68682a56-5bc4-4bfb-be4e-2e588335549c', name='EKPO', alias='EKPO', data_pool_id='be065bab-bc94-4f2e-81d3-f4df1e126e2a'),
	DataModelTable(id='a29074bc-240a-4bc3-b050-0b35e7f0000f', data_model_id='68682a56-5bc4-4bfb-be4e-2e588335549c', name='LFA1', alias='LFA1', data_pool_id='be065bab-bc94-4f2e-81d3-f4df1e126e2a')
]

5. Reload data model¶

Note that the add_table() method only creates a reference of the data pool table inside our data model but does not reload the data model. For that, we have to call the reload() method:

In [19]:

Copied!

data_model.reload()
data_model.reload()

[2024-12-02 16:11:05,823] INFO: Successfully triggered data model reload for data model with id '68682a56-5bc4-4bfb-be4e-2e588335549c'

[2024-12-02 16:11:05,824] INFO: Wait for execution of data model reload for data model with id '68682a56-5bc4-4bfb-be4e-2e588335549c'

This method will load the data for all tables inside our data model. However, if we only want to load the data for selected tables, we can also perform a partial_reload() and specify inside data_model_table_ids the table IDs, for which we want to load the data:

In [20]:

Copied!





tables = data_model.get_tables()
ekko = tables.find("EKKO")
ekpo = tables.find("EKPO")
data_model.partial_reload(data_model_table_ids=[ekko.id, ekpo.id])
tables = data_model.get_tables()
ekko = tables.find("EKKO")
ekpo = tables.find("EKPO")
data_model.partial_reload(data_model_table_ids=[ekko.id, ekpo.id])

[2024-12-02 16:11:05,966] INFO: Successfully triggered data model reload for data model with id '68682a56-5bc4-4bfb-be4e-2e588335549c'
