Options for custom functions

It is possible to create custom functions for Isah ML. Customization can take the following forms:

• Adding new functions
• Modifying standard functions.

To be able to create customizations, a file named 'IsahMobileCustomizing.dll' must be developed and placed in the Isah ML folder. This file will be loaded on startup to make the custom functions available. The Isah ML Info form shows whether a customization dll has been loaded and displays its version.

The IsahMobileCustomizing.dll must be a .NET assembly developed with Visual Studio. The creation of custom functions therefore requires a development environment.

Custom functions will usually also require tables. This means that the synchronization schedule will generally have to be extended in order to use custom functions. The steps involved are:

1. Add a new table to the synchronization schedule by using Isah Mobile Config.
2. Link the table to a function by adding it to the MT_SyncFunctionTables table.
3. Enable change tracking for the table.

The programming interface (API) and the setup of the development environment are described in the document Isah Mobile Logistics: SDK.
