NAV 2013 R2 | Keys, Keygroups and SetCurrentKey

With NAV 2013, the Classic Client and the Native Navision database were discontinued.

One of the possibilities that arised was improving the SQL story in NAV.

This was done first by implementing SETAUTOCALCFIELDS and the possibility to do CALCSUMS and FlowFields without specifying a SumIndexField. This is released in NAV2013.

In NAV2013 R2 the story continues

Keys

In the Native database the structure how Navision maintained Keys was perceived as revolutionairy and a main part in the success of the Application and its architecture.

Within a Key one could specify SumIndexFields. These are decimals that then would be totalled in the background without writing code.

Everything in NAV like G/L, Inventory and Jobs is based on that principle. You will not find any Application code in NAV that totals entries.

To be able to sort something a Key was required in the Native database. A maximum of 40 keys were allowed. This is different in SQL Server.

SQL Server can sort without having an Index (the name for Key in SQL Server). Therefore with the Native database being discontinued the possibility opened to change the Key story in NAV.

Therefore with the introduction of NAVA 2013 R2 it is no longer required to define a Key on a table to sort data.

It is now possible to sort on any column in the UI.

And it is also possible to sort on any field from AL code.

SetCurrentKey no longer requires a Key to be created in the table.

KeyGroups

Another change that has been imlemented is the discontunation of KeyGroups.

After internal debate and investigation Microsoft decided that the active use of the feature was not enough to justify the effort of moving the feature from Classic Client to PowerShell.

Do you agree with this?
