A filter has been applied to the MSW/PSW that hides a production line or item that is visible on one frame/grid and not another. The system will still select/focus on the item record, even if not visible.

Also, the sequencing horizon may be less than the MSW scheduling horizon.

If you are viewing items on a work center resource, the setting of the Pur/Mfg field does not have an impact on this issue; however, setting the BOM and routing does have an impact. Likewise, BOM/routing does not impact viewing an item on the production line, but the setting of the Pur/Mfg field does.

Remove the filter. The selected record displays as selected.

Change the horizons through the Options pull-down menu by selecting Preferences, then the Search tab in the Planning and Scheduling Workbenches. Verify that for both work center and production lines, there is an active supply/demand for the item within the search history/future horizon.

If viewing items on a production line, set the Pur/Mfg field to L in Item Data Maintenance (1.4.1).
