Adding activities
You can add activities to an operation by adding rows in the Microsoft Excel sheet for these activities. In addition, you can add a Time column to enter the duration time for each activity.
| Header1 | Item | Item | Item | Description | Activity | Activity | Activity | Activity | Activity |
|---|---|---|---|---|---|---|---|---|---|
| Header2 | Process | OP | Activity | Description | Time | Unittime | Frequency | Category | |
| Header3 | Process | OP | Activity | ||||||
| Title | Proc | Oper | Activity | Desc | Act-Desc | Time | Unit-time | Frequency | Category |
| Act-Process | |||||||||
| OP10 | Operation10 | ||||||||
| OP20 | Operation20 | ||||||||
| Act1 | activity 1 | 6 | 6 | 1 | VA | ||||
| Act2 | activity 2 | 10 | 10 | 2 | VA | ||||
| Act3 | activity 3 | 3 | 3 | 3 | NVA | ||||
| OP30 | Operation30 | ||||||||
| OP40 | Operation40 | ||||||||
| Act4 | activity 4 | 2 | 2 | 3 | VA | ||||
| Act5 | activity 5 | 4 | 4 | 2 | NVA | ||||
| OP50 | Operation50 | ||||||||
| OP60 | Operation60 | ||||||||
| OP70 | Operation70 |
You must place activities on separate rows. These activities then appear in Manufacturing Process Planner as follows.
Creating the PERT sequence on import
During import, the tcexcel_import utility can create the PERT sequence on the structures. The sequence is based on the hierarchy as listed in the template.
Example:
Create the following in the import template.
After importing, the following PERT sequence is created.
Importing the frequency of an activity
When importing plant structures, the tcexcel_import utility can also populate the frequency.
Note
The frequencies are numeric values.
Importing the category of an activity
When importing plant structures, the tcexcel_import utility can also populate the category.
Note
The category values are based on an existing (OOTB) LOV.
Importing the unit time of an activity
You can also use the tcexcel_import utility to populate the unit time of the imported plant structure, as shown in the Activities view above.
To do so, create the following in the import template.
Header1 Activity
Header2 Unittime
Note
The unit times are numeric values.
