NAVision Dimension concept
• Dimensions in NAV are codes which is user defined (ex.: AREA)
• Dimensions are append to transactions when posting documents
• With Dimensions user can analyze posted data
Analyzing General Ledger data
• GL data are in NAV table “G/L Entry”• Data are writen sequentialy during post
procedure (primary key is “Entry No.”)• Every row in G/L Entry can have many
Dimension rows
• For analyzing data we must know the content

DWEXCEL +
PowerPivot
• After initial Excel setup (connection setting to DW) power user can load and design his own PowerPivot tables• User can refresh data in PowerPivot table by table or all tables
in one step• Table in PowerPivot is refreshed complete (load whole data
again !)
PowerPivot data viewEvery loaded table is visible in separate sheet (see at bottom).
