Create time blocks

A time block is an essential part of a Free Blocks, Resource Breaks, Maximum Hours, or Maximum Workspans constraint. For example, a Maximum Hours constraint specifies the maximum number of hours that a resource can be used within a particular time block. Before you create one of these types of constraint, you must create an appropriate time block to use.

A time block specifies the block of time that will be constrained; the block must consist of contiguous periods. However, the block can "wrap" over the boundary between days; for example, you can create an "all week" time block.

A time block might describe an entire week, a whole day, or a few hours on a particular day. In the editor, the time block is coloured blue.

Three period grids that each contain a different example of contiguous blue period blocks

To create a time block, follow these steps:

  1. In the main EDRDM window, find the Time Constraints area.
  2. In that area, click New in the Time Blocks row.
  3. EDRDM opens a form that you can enter the new time blocks's properties into.
    • Single-line text properties such as Name and Description: Click the property box, then type. If you do not specify a host key in the Host Key box, EDRDM will generate a unique host key.

      Example text in a single-line text property

    • Multi-line text properties such as User Text 1: Click the property box. In the popup window that is displayed, click and type, then click OK.

    • Department: In the Department row, click the property box. Then, in the list that is displayed, select a value (Note: the example below is from the Suitability form). In conjunction with the permissions that are specified in Authorisation Manager, the Department property can determine who is able to edit or delete this time block.

    • Tags: In the Tags row, click the property box, then select values.
  4. To begin specifying the time block, click the property box in the Weeks row. The time block editor opens.

  5. Select which weeks and periods are included in the time block. You can use the same actions that you use when you specify period availability, see Edit the availability of periods. The following list describes how specifying a time block differs from editing period availability:
    • To edit the inclusion of weeks, you make changes in the Week Pattern for Timeblock bar.
    • To set periods to included, click the blue box; to set periods to not included, click the white box. Then, follow one of the instructions that you use when you specify period availability. However, because the block must consist of contiguous periods, you cannot click and drag the mouse outside the grid (either above the grid or down its side).
  6. To close the time block editor, click the cross Dark cross at its bottom corner.
  7. To save the new time block, click Apply. Or, to save it and close the form, click OK.
  8. Note: If you have not yet clicked Apply and you do not require the new item, click Discard; the new item is deleted. Or, to discard the item and close the window, click Cancel.

Alternatively, if you want to look at another time block when you create one, click Show (beside the New button). EDRDM opens a list of time blocks. In that window, click the plus icon below the item list (see below) to create an item. In the new row, enter the new item's properties, then click Apply to save the item (or OK to save the item and close the window). To specify the time block, click the down arrow in the Periods column. If a property that you want to use is not present, add it to the table.
