Entry screen

Selection of the work orders

Leave the default end or required completion date for the work orders or select a different date. Work orders with an end date prior to the defined date within the defined ranges will be selected. Then type in, or select the calculation formula to be applied. 

Select the type of processing to be performed, as follows:

  • Deschedule. Process all work orders currently at status 'Scheduled' or 'Reschedule'. Planned dates are reset and load reduced.
  • Flag for reschedule. Process all work orders currently at status 'Scheduled'.

Then select the types of work orders to be included in the run.

Start/end ranges

A number of ranges are displayed.

  • To deschedule or reschedule all applicable work orders, leave all the fields blank.
  • To deschedule or reschedule selected work orders, type in the required ranges. Leave the first field blank to include the lowest value or the second field blank to include the highest value.

A log file displays the results of the run. Where appropriate it includes information which should be noted or acted upon before the work orders are processed further.

If the content of this field includes a character such as an exclamation mark "!" this field links to the structure of the project. The character is the separator between a project code and the project operational (task) structure. For example, if a material task code is "USA-P3" and a project code is "USA12345678", this field displays a link to the project operational structure as "USA12345678!USA-P3".
