This article is excerpts from latest
book Microsoft Dynamics AX Implementation
Guide by Yogesh Kasat and JJ Yadav ,
about one of the important topic in Microsoft Dynamics AX implementation
process—configuration data management.
The configuration of an ERP system is
one of the most important parts of the implementation process. Configuration
means setting up the base data and parameters to enable your product features
such as financial, shipping, sales tax, and so on.
Microsoft Dynamics AX Implementation Guide-
Microsoft Dynamics AX has been
developed based on the generic requirements of various organizations and
contains the business processes belonging to diverse business segments. It is a
very configurable product that allows the implementation team to configure
features based on specific business needs. During the project, the
implementation team identifies the relevant components of the system and sets
up and aligns these components to meet the specific business requirements. This
process starts in the analysis phase of the project carrying on through the
design, development, and deployment phases.
Configuration management is different
from data migration. Data migration broadly covers the transactional data of
the legacy system and core data such as Opening balances, Open AR, Open AP,
customers, vendors, and so on. When we talk about configuration management, we
are referring to items like fiscal years and periods, chart of accounts,
segments, and defining applicable rules, journal types, customer groups, terms
of payments, module-based parameters, workflows, number sequences, and the
like. In a broader sense, configuration covers the basic parameters, setup
data, and reference data which you configure for the different modules in
Dynamics AX.
The following diagram shows the
different phases of configuration management:
In any ERP implementation project,
you deal with multiple environments. For example, you start with CRP, after the
development you move to the test environment, and then training, UAT, and
production, as shown in the following diagram:
One of the biggest challenges that an
implementation team faces is moving the configuration from one environment to
another. If configurations keep changing in every environment, it becomes more
difficult to manage them. Similar to code promotion and release management
across environments, configuration changes need to be tracked through a
change-control process across environments to ensure that you are testing with
a consistent set of configurations.
The objective is to keep track of all
the configuration changes and make sure that they make it to the final cut in
the production environment.
The following sections outline some
approaches used for configuration data management in the Dynamics AX project.
The golden environment
An environment that is pristine
without any transactions—the golden environment—is sometimes referred to as a
stage or pre-prod environment. Create the configurations from scratch and/or
use various tools to create and update the configuration data. Develop a
process to update the configuration in the golden environment once it has been
changed and approved in the test environments.
The golden environment can be turned
into a production environment or the data can be copied over to the production
environment using database restore.
The golden environment database can
be used as a starting point for every run of data migration. For example, if
you are preparing for UAT, use the golden environment database as a starting
point. Copy to UAT and perform data migration in your UAT environment. This
would ensure time you are testing with the golden configurations (If the
configuration is missing in the golden environment, you would be able to catch
it during testing and fix your UAT and the golden environment too).
The pros of the golden environment
are given as follows:
·
The golden environment is a single environment for
controlling the configuration data
·
It uses all the tools available for the initial
configuration
·
There are less number of chances for corruption of
the configuration data
The cons of the golden environment
are given as follows:
·
There is a risk of missing configuration updates
due to not following the processes (as the configuration updates are made
directly in the testing and UAT environments).
·
There are chances of migrating the revision data
into the production environment like workflow history, address revisions, and
policies versions.
·
There is a risk of migrating environment-specific
data from the golden environment to the production environment.
·
This is not useful for a project going live in
multiple phases, as you will not be able to transfer the incrementalconfiguration data using database restore.
·
You must keep the environment in sync with the
latest code.
Copying the template company
In this approach, the implementation
team typically defines a template legal entity and configures the template
company from scratch. Once completed, the template company's configuration data
is copied over to the actual legal entity using the data export/import process.
This approach is useful for projects
going live in multiple phases, where a global template is created and used
across different legal entities. Whereas, in AX 2012, a lot configuration data
is shared and it makes it almost impossible to copy the company data.
Building configuration templates
In this approach, the implementation
team typically builds a repository of all the configurations done in a file,
imports them in each subsequent environment, and finally, in the production
environment.
The pros of building configuration templates are as follows:
·
It is a clean approach.
·
Utilize DIXF, DAT/DEF files to export the
configuration and import them into a new environment.
·
You can version-control the configuration file.
·
This approach is very useful for projects going
live in multiple phases, as you can import the incremental configuration data
in the subsequent releases.
·
You can create additional code to automate export
and import process or utilize LCS Configuration manager tool to export and
import configuration from one environment to other.
This approach may need development
efforts to create the X+ scripts or DIXF custom entities to import all the
required configurations.
Summary
Clearly there are several options to
choose from for configuration data management but they have their own pros and
cons. While building configuration template is ideal solution for configuration
data management it could be costly as it may need significant development
effort to build custom entity to export and import data across environments.
The golden environment process is widely used on the implementation projects as
it’s easy to manage and require minimal development team involvement.
About Microsoft Dynamics AX Implementation Guide
ERP implementations are complex by
nature and just like configuration data management has so many moving part. In
order to make implementation project successful project managers, solution
architect and leaders are expected to know all the aspects.
The book Microsoft Dynamics AX Implementation Guide is
one of the first books covering the entire Dynamics AX implementation lifecycle
with real life learnings and examples, providing stage by stage or phase by
phase instructions for Project Managers, Business users and Solution
Architects. Supported by practical examples to validate recommendations
and common pitfalls.
This book provides a summary of the various facets for running a
successful Microsoft Dynamics AX project without going through expensive and
time consuming training courses. Aspects covered include: Management,
Functional/Business analysis, Technical design with code examples, and
Infrastructure.
