What a planner means
Display all curtain attachments in the Gantt Chart is Oracle Display all curtain attachments in the Gantt Chart. Activities window. Layout Options bar → Attachments, Curtain, Show All. Show All is only available if at least one curtain is currently hidden. It is a how-to. It is not stored as its own table. It does not create, edit, or delete a relationship. It is not the Curtain object note, not Hide all curtain attachments, not Hide a curtain attachment, not Add a curtain attachment, not Delete a curtain attachment, not TASKPRED, not EPPM copied onto Professional, and not Microsoft show highlight.
Oracle does print a how-to titled Display all curtain attachments in the Gantt Chart. Oracle does not print a menu item named Display all curtain attachments. The path that how-to prints is Layout Options bar → Attachments, Curtain, Show All. Do not invent View > Display all curtain attachments. Do not invent View, Attachments on this how-to (that page fetched does not print View, Attachments).
Oracle Display all curtain attachments in the Gantt Chart (Professional):
- "In the Activities window, click the Layout Options bar and choose Attachments, Curtain, Show All. The Show All menu item is only available if at least one curtain is currently hidden."
That how-to fetched prints no OK, no Apply, no Save, no Yes, no double-click, no Display checkbox, no Tip, and no View, Attachments. Do not invent those on this how-to.
Hide all curtain attachments is a different how-to. Hide All, not Show All. See Hide All Curtain Attachments in the Gantt Chart.
Hide a curtain attachment is a different how-to. Double-click one curtain; clear Display. See Hide a Curtain Attachment in a Gantt Chart.
Curtain is a different object note. Leave Curtain Attachment as the object.
Professional vs EPPM
Professional — Activities window; Layout Options bar → Attachments, Curtain, Show All. Only if at least one curtain is hidden. No OK / Apply on that page.
EPPM web — Oracle Working with the Activity Gantt Chart does not print Show All. Do not copy this Professional how-to onto EPPM.
Primavera Cloud is a different product. Do not copy it here.
XER
The how-to is not an XER table. Oracle’s project XER map TOC has no CURTAIN / SHOWALL table. Do not invent a view %T. Showing all curtains does not write TASK. Layouts travel as .plf. A Viewer cannot reconstruct that the planner used this how-to.
Microsoft Project
Microsoft Project can show date-range highlights. Do not map that as P6 Display all curtain attachments in the Gantt Chart. Do not claim MPXJ writes a real MPP.
