Clearing Preschedule Data

...

Review the preschedule data, you may find that some blocks have volume but no tonnes, or vice versa.

  1. Check the blocks affected in Rapid Reserver:

    1. Navigate to Rapid Reserver > Designer tab > select the block from APS Preschedule error message description > check its tonnes and volume in the Reserves tab at the bottom of the screen > most likely you will see the same missing values.

    2. Some blocks can be outside of the Block Model coverage > make sure you are using Block Model Gap Filling function, where default densities (this is essential) and tonnes are assigned (enable “Fill Block Model Gaps' in the Settings step).

    3. If Block Model Gap Filling is used correctly, but the error message in APS Preschedule persists, check your Reserves mappings in the Block Model step > Reservable Model Generator.

      1. Change the volume and tonnes expressions to exclude blocks with Zero density, ie:

        1. volume = N("density") > 0 ? N("size (X)")*N("size(Y)")*N("size(Z)") : 0, or N("size (X)")*N("size(Y)")*N("size(Z)");

        2. tonnes = N("density") > 0 ? N("size (X)")*N("size(Y)")*N("size(Z)")*N("density") : 0, or N("density") > 0 ? N("size (X)")*N("size(Y)")*N("size(Z)")*N("density") : N("size (X)")*N("size(Y)")*N("size(Z)")*2.5 (density).

      2. Regenerate your Reserves Model and review the changes.
