On the Roll/Lapse Detail Pre-Selection in CORE, why is the action column greyed out for me?

If your selections in the Action column are greyed out and the system does not allow you to choose and view other selections from the provided dropdowns under the Action column, then your CORE security profile does not have the Dept. General Accounting Table Maintenance or Dept. Procurement Roll/Lapse Table Maintenance roles needed to make any updates on this table. To have one of these security roles added to your CORE security profile, you will want to speak to your department appointed CORE Security Administrator. If you do not know who this person is, you will want to speak to your supervisor or department controller.
