Hi David,
When Material is being processed Inbound or Outbound there are tasks that need to be confirmed by Warehouse example Picking of Material, Loading of Material etc, If there is a requirement for Processing Material Inbound or Outbound without such tasks being updated in the system and a direct Receipt or Issue is all that is required then the Without Task Logistics Model is required and this enables use of Post Good Issue and Post Goods Receipt in the Outbound and Inbound Logistics respectively.
Best regards
Nick
