#GPPT Adding Virtual Fields to Item Maintenance Version 2

GP Power Tools Build 32 added Custom Tables as a new feature to the Developer Tools module. Custom Tables can automatically create and maintenance SQL tables in company (or system) databases as defined by the definition in the Custom Tables Setup window.

This is an updated version of the #GPPT Adding Virtual Fields to Item Maintenance project which uses a Custom Table to store the data rather than the DUOS. Easy access to the Custom Tables is provided by a series of Custom Table Buffer Helper Functions which replicate how Dexterity table buffers work.

#GPPT Using .Net Math Functions from Microsoft Dynamics GP

A recent customization project I was working on using GP Power Tools required the calculation of a square root as part of some number crunching needed to work out material quantities on a Sales Order Processing transaction.

While Dexterity (the language behind Microsoft Dynamics GP) is great at accounting style mathematics (as per a standard calculator), it does not have advanced functions for powers, logs, and trigonometry (as per a scientific calculator). This means that there is no “native” method to calculate a square root.

However, Dexterity (from v14.0 onwards) has a .Net Interop which allows you to import and call .Net libraries directly from your Dexterity scripts. This example shows how to call the System.Math library as well as other advanced techniques, such as Custom Forms and Virtual Fields.

#GPPT Making Window Fields Required and Why It Does Not Always Work

For a field to behave as required, there are a number of different factors that must all fall into place. This article will explain the theory and what can go wrong. Links to examples with sample code will be published over the next week.
