Improvements in Shop Floor Pre-calculation Module

If hours are booked based on pre-calculation and no operations have been selected on the employee, no PC operations are shown in the Shop Floor module 'Pre-calculation' if 'Own Operations' or 'All Operations' are selected. This prevents unintentional loading of all PC operations, which could lead to a timeout in certain situations.

If hours are booked based on planning operations and no resources have been selected for the employee, no planning operations will now be shown under 'Own Resources'.

The searches 'Own' and 'All' could no longer be selected in the 'Pre-calculation' module. We have repaired this.
