1. A computer-implemented method for managing access to and updating warehouse data in at least one online data system wherein a security role is established for each user of warehouse operation functions for the online data system, the method comprising: examining warehouse data and updating a status of warehouse operations; detecting a security role of a current user accessing the data system by determining a work responsibility role of the current user; rendering one or more warehouse operation functions and the status via an interface; receiving a selection of one of the warehouse operation functions; determining whether the security role of the current user authorizes access to the warehouse operation function selected; prohibiting access to the warehouse operation function selected in response to determining the security role does not authorize access to the warehouse operation function selected; rendering a second interface corresponding to the warehouse operation function selected in response to determining the security role does authorize access to the warehouse operation function selected; receiving input via the second interface to perform one or more of the warehouse operations; executing the warehouse operations for which the input is received via the second interface; updating at least one online data system based on the warehouse operations executed; and generating one or more grief tables for storing items which cannot be received into the online data system; tracking via the grief tables, the items which cannot be received into the online data system; generating one or more auxiliary shipping tables for storing items in the process of being shipped; and tracking via the auxiliary shipping tables at least one of intermediate issuing or intermediate shipping activity of one or more items between picking the items and final issuing or shipping of the items.
