To the database documentation To the JTLwawiExtern.dll docs

Our merchandise management system does not have a stand-alone plug-in module. However, there are numerous interfaces that you can use to map many of the applications you require on a daily basis. Here are your options:

Database

You can use the database to:

Use prepared database views (read access)
Example: Read out data for reporting tools and statistical evaluations
Use a range of database functions (read access)
also write to the database using stored procedures
Examples: Create / update / cancel orders, post stocks, create / update invoice corrections

Some retailers have a healthy respect for accessing the database directly. However, the methods described above are a good way of ensuring that the data in your database remains consistent and that database integrity is maintained. Contact an appropriately experienced service partner if you do not have an in-house database expert.

JTLwawiExtern.dll

Via the JTLwawiExtern.dll from JTL-Wawi you can, for example:

Create / print / generate PDF / email / export all forms
You can use all functions from our template module
Trigger all JTL workflows you have configured
You can use all functions from our workflow module

Anyone familiar with the possibilities of JTL workflows knows that this alone opens up a land full of attractive automation options. If required, contact a JTL service partner who is well versed in JTL workflows.
