| | Activities (tipcs4101m000)In the overview session
you can list the activities by project. In the details session
you can define activities. Activities are used to perform network planning by project,
and to: - Determine the rough
material and capacity requirements of the project which are planned with
activities;
- Control the (final)
assembly planning for the project;
- Define modules in
module planning;
- Record a project
structure in the Project Structure (tipcs2115m000) session.
Note A record cannot be deleted if: - The project has
Canceled, Finished, Closed or Archived status;
- The hours spent are
> zero;
- Activity is used in
the Project Structure (tipcs2115m000) session
- Activity is used in
the Activity Relationships (tipcs4110m000) session
- Activity is used in
the Module Planning (tipcs4120m000) session
Project A collection of manufacturing and purchasing actions that are
performed especially for a particular customer order. A project is initiated by
a customer order for items having a To Order order policy. The purpose of a project is to plan and coordinate the production
of these items. For a standard-to-order production, the project is only
used to link the item with the customer order. Otherwise, a project can
include: - Customized item data (BOMs and routings)
- Project planning (activity planning)
A budget is a special type of project. A budget is used to
plan and estimate, not to carry out production. Note It is not allowed to
have a project of the Budget type. Budgets are only used for financial transactions, so you cannot add
activities for a budget. Activity This code identifies an activity in the network planning for a
project. Default value As a rule, LN takes the last
sequence number incremented with1. Search Key An alternative form of a description used for convenience
during searching. Typically, it is an abbreviation, an acronym, or a mnemonic
alternative to a full description. Task The task you want to link to the
activity. The task entered is used: - in the Project (PCS) Hours (bptmm1170m000) session when hours are entered for an activity;
- to store more
detailed information about the activity.
Work Center A specific production area consisting of one or more people
and/or machines with identical capabilities, that can be considered as one unit
for purposes of the capacity requirement planning and detailed scheduling. Activity Manager A person responsible for planning or carrying out a project
activity. Capacity Load Table Capacity load tables indicate how the rough capacity
requirement is divided over the activity duration. The percentage of the lead
time (activity duration) is on the horizontal axis. The vertical axis shows the
percentage of the capacity requirement (that part of the activity which must be
finished after a certain activity duration). This capacity requirement is the
rough capacity recorded for the activity. Rough Capacity Requirements The globally needed capacity in hours for the execution of the
relevant activity. Enter the estimated
capacity-requirements in hours for the relevant activity. Using the Generate Network Planning (tipcs4210m000) session, the capacity-load table is used for
planning the global capacity-requirements for the relevant activity. Planning Factor Enter the planning factor that is used in calculating the
default activity duration. The planning factor
indicates how many employees or machines are employed simultaneously for the
execution of an activity. LN only uses this factor to calculate the
default duration of the activity on the basis of the global capacity
requirements and the available hours by day. Available Capacity Enter the available capacity in hours per day. This capacity is
used to calculate the default activity-duration. The planning factor enables
you to record the available capacity in hours per day for each employee or
machine. Based on this capacity, LN calculates the default
duration of an activity using the appropriate formula: Default activity duration = Rough capacity requirement /
(Planning factor x Available capacity) Activity Duration Enter the activity duration in days. LN determines the default
activity duration as follows, based on: - The estimated
capacity requirements
- The planning factor
- The available
capacity
Activity Duration = Estimated capacity requirements /
(Planning Factor x Available Capacity) Earliest Start Date The earliest start date for the activity is the earliest date
on which the activity can be started. This date is determined using the Generate Network Planning (tipcs4210m000) session. Latest Start Date The last start date of the activity is the last date on which
the activity can be started. Determine this date by using the Generate Network Planning (tipcs4210m000) session. Earliest End Date The earliest end date of the activity is the earliest date on
which the activity can be finished. Determine this date by using the Generate Network Planning (tipcs4210m000) session. Latest End Date The latest finish date for the activity is the latest date on
which the activity can be finished. This date is determined using the Generate Network Planning (tipcs4210m000) session. Total Float The total float of an activity is the maximum time expressed in
(working) days in which that activity can be shifted without affecting the
planned completion date of the relevant project. The total float-time
is calculated: Total Float = Latest
Finish - Earliest Start - Activity Duration The latest finish
date and earliest start date are expressed in project days. Free Float The free float is the number of (work)days that the start of an
activity can be delayed without affecting the float of subsequent activities. The free float is
determined by the network planning process. It cannot be modified by the user. Desired Start Date The desired start date is the date on which you want to start
the execution of the relevant activity. This date is only used for information.
However, the desired start date is compared to the earliest and latest finish
dates and the reference date by the Generate Network Messages (tipcs4211m000) session, which can result in the creation of
exception messages. Desired End Date The desired finish date is the date on which you want to stop
the execution of the relevant activity. This date is only used for information.
However, the desired finish date is compared to the earliest and latest finish
date and the reference date with the Generate Network Messages (tipcs4211m000) session, which can result in the creation of
exception messages. Actual Start Date Enter the actual start date, provided that the Percentage Completed field does not read 100%. Note The actual start
date is also updated by the Process Hours and Expenses (bptmm1203m000) session once you have entered hours for the
relevant activity using the Project (PCS) Hours (bptmm1170m000) session. Actual End Date Enter the actual finish date, provided that the field
Percentage Completed does not read 100%. Note The actual end date is updated if you: - Enter hours for the
relevant activity in the Process Hours and Expenses (bptmm1203m000) session.
- Execute a network
calculation in the Generate Network Planning (tipcs4210m000) session.
Activity Estimation If this check box is selected, the field indicates
whether the relevant activity must be included in the estimated cost-price
calculation for the project. This can be especially important for indirect
activities, such as engineering. Status Indicates the current progress of the project. Aggr. Estim. Cap. [H] The aggregated capacity requirements in hours, depending on
work center where the activity is scheduled to be carried out. The aggregated
capacity requirements are calculated with the Aggregate Estimated Capacity to Project (tipcs4201m000) session on the basis of the
project structure and the project engineering. This is only possible if the
operations have been linked to activities in the routing. Dependent on the
value of the Critical Capacity for Planning field in the Work Centers (tirou0101m000) session, Man Capacity or Machine Capacity is used to calculate the aggregated capacity
requirements. The aggregated
capacity-requirements are only shown for your information and can be used for
checking or monitoring the rough planned hours by activity. Progress Spent Critical Capacity The actual hours spent on the relevant activity. Based on the
transaction hours linked to the activity, LN automatically updates
this value in the Process Hours and Expenses (bptmm1203m000) session. LN displays the number of hours
spent as calculated by the Generate Network Planning (tipcs4210m000) session. Actual Man Hours The actual man hours that are the posted to and processed by People. Actual Machine Hours The actual machine hours that are the posted to and processed
by People. Critical Capacity for Planning The value of the Critical Capacity for Planning field in the Work Centers (tirou0101m000) session for the relevant work center. Automatic Update of Percentage Completed If this check box is selected, the Percentage Completed field is automatically determined if you use either the Process Hours and Expenses (bptmm1203m000) session when hours transactions are
processed, or if you use the Generate Network Planning (tipcs4210m000) session when a network calculation is
performed for the project. Percentage Completed Enter the percentage completed for the activity. You can only
enter a percentage if the Automatic Update of Percentage Completed check
box is cleared. If the Automatic Update of Percentage Completed check
box is selected, the percentage completed is automatically determined. The
calculation is as follows: If hours are entered in the Rough Capacity Requirements field: Percentage completed = Spent hours / Rough capacity
requirements If no hours are entered in the Rough Capacity Requirements field: Percentage completed = Spent hours / (Planning factor
x Available capacity x Actual duration)
The percentage
completed shows the activity's progress. The Spent Critical Capacity field
is updated if you book hours for the activity in the Hours and Expenses by Employee Overview (bptmm1100m000) session. If the booked hours for
the activity exceed the number of hours in the Rough Capacity Requirements field, you would expect a percentage in the Percentage Completed field that is higher than 100%. However, the value displayed
in the Percentage Completed field will never be higher than 99%. The reason is that if
the percentage is not higher than 99%, you can continue booking hours. If the Automatic Update of Percentage Completed check
box is cleared, you can change the percentage manually to 100%. If the
percentage is 100%, you cannot book extra hours anymore. Note Because of the nonlinear distribution of capacity
requirements, the percentage completed is not related to the lead time but to
the global capacity requirements. If you choose an automatic calculation of the
percentage completed, this percentage is determined on the basis of the global
capacity requirements and the actual hours spent. | |
