Instore Management Worksheets were released in LS Nav 10.10, released in December 2017, with the aim to replace Store Inventory Worksheets. Until now, users could choose to use either InStore Management Worksheets or Store Inventory worksheets in order to create their own store-specific inventory processes. With this release, we have removed the InStore Management Worksheets, activating Store Inventory instead. InStore worksheets are based on standard NAV objects, and with every journal line entered, the system runs many unnecessary validations. Sometimes, in large installations, this results in waiting in deadlocks. Store Inventory Worksheets, on the other hand, are based on LS Nav's own object range, on which we have full control, speeding up the system. If you have not already activated Store Inventory before upgrading to LS Nav 11.05, you should consider doing so, if you wish to upgrade the Inventory masks (in Store Inventory Setup in earlier versions).
