| Activity Relationships (tipcs4110m000) |  |
| Use this session to maintain the relationships between a project's activities, thus enabling a network planning for the project to be carried out. This session enables you to determine the sequence of activities and the start and finish time of an activity compared with the preceding or next activity. Note Relations between activities are recorded by manual input or by running the Copy Project (tipcs2210m000) session. Relations between activities are used in the time planning and the rough capacity planning in Network planning. Related topics Network planning
Fields | Description
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. Related topics Project types
Status | The status of the project.
Sequence Number | The number that identifies a data record or a step in a sequence of activities. Sequence numbers are used in a large variety of contexts. Usually ERP LN generates the sequence number for the next item or step. Depending on the context, you can overwrite this number. You can sometimes influence the numbering by setting the corresponding parameters. By default, ERP LN shows numbers in the sequence of 10, 20, 30, and so on. Numbering is free. However, you are recommended to adopt these default values, because the intervening numbers are necessary to insert any activity relationships.
Preceding Activity | The code of the activity for which you want to create a relationship with another activity.
Next Activity | Enter the code of the activity which has a relationship with a preceding activity.
Relationship Type | The relation type indicates the relationship between the preceding and the next activity. Allowed values Possible values
Float Time (Day) | Enter the absolute relationship float-time in days. Note A positive float-time always means a positive shift of the next activity with respect to the preceding activity. Example: Two activities have an end-start relationship. If these activities directly link up with each other, the absolute float-time is zero. If the next activity is to start four days before the end of the preceding one, you can enter an absolute float-time of minus four. If the next activity is to start five days after the end of the preceding activity, the absolute float-time is five. Related topics Float times
Float Time (in Perc) | Enter the relative relationship float-time as a percentage of the duration of the preceding activity. Note A positive float-time always means a positive shift of the next activity with respect to the preceding activity. Related topics Float times
