Figure 143  Elements of an Parallel Activity in the workflow.

 

Examples

loopLocationSetId

For a workflow, a location-loop can be defined in which each location (site) in a location set is run separately. The $LOOP_LOCATION_ID$ tag in the configuration can be used to point to the corresponding locationID of the current location. This is useful in combination with (related location) Constraints, because then it is possible to filter a locationSet on the basis of the $LOOP_LOCATION_ID$.

Examples

The workflow below runs seven moduleInstances. If the first moduleInstance fails in this example all other processing is stopped. If any of the other activities fail the processing The workflow below runs seven moduleInstances. If the first moduleInstance fails in this example all other processing is stopped. If any of the other activities fail the processing will continue.

You can loop over a particular locationSet using the following config. In the ModuleInstance (e.g. exportActivity of a GeneralAdapter) in every 'loop' the $LOOP_LOCATION_ID$ tag will be replaced with the 'actual' locationId.
