To create the products in the right order you can either use a standard Feeder with the “Table” FeedMode to read which product needs to be created when. Or you could use the component “ExcelReader” in the Misc file in the eCat or the AddOn “VariableCache” with an If or switch statement to create different products and assign them different properties (there is an example of that in the Automatic Warehouse System layout, in the Layouts file of the eCatalog).
When both products are assembled, you can either choose one of them as a “parent” where the data will be stored or replace them by a 3rd product. You could use an Assign statement to add the process time contained in both products.
For example :
To add to Tilma’s reply, the component “Advanced Feeder” in 4.10 eCatalog has something very similar. It creates the components on the right order and gives each created component the right properties that were read from the table.
The component comes with an example of each feed mode that you can open by clicking the note. I’d recommend CreationMode Batch or Timestamp, you just have to add the intervals/creation times manually to the spreadsheet.
