Assign resources
You can assign resources to operations in a process structure or to work areas in a plant structure.
Procedure
- If necessary, import the resources into the database.

- Create a Microsoft Excel spreadsheet that includes a column with the following keywords:
Add the Relation keyword to the Header1 row.
Add the Resource keyword to the Header2 row.
In the Header3 row, type the occurrence type of the resource, for example, Tool or Resource.
- Assign these resources operations in the process structure as follows.

Inspection
Importing this sheet results in the following structure. There are several points to note about this structure:
The Relation column must contain the item IDs (not the names) of the resources or work areas.
Resources that are classified in the database are indicated as such in the structure by the classified symbol . The import utility can assign both classified and nonclassified resources.
The resources must already exist in the database.
You can assign multiple resources to a single BOM line by separating them with a semicolon.
You can specify an occurrence type in Header3 of the Relation column that is then used for all the relations. If, however, you enter an occurrence type in the cells of the relation column (designated by occurrence type~item ID), this occurrence type is used instead of the one in Header3. In the preceding example, for res_machine_001, the MachineTool occurrence type is used instead of the default Tool.
