Copy Data on Save

Description

This module enables data to be copied from one place to another when you save a form. You can set up multiple copy processes to different projects or even to other fields in the same project.

Copying the value of one field to multiple fields in the destination is supported. (Copying multiple fields to a single field is also supported but only the last value will be retained!)

Enable and configure the module in the source project. No action is required in the destination project.

Repeating Data

Behaviour with repeating data is dependent on whether the field is repeating in the source, or in the destination, or both, as follows:

Source	Destination	Behaviour
Not repeating	Not repeating	To non-repeating field
Repeating	Not repeating	To non-repeating field
Not repeating	Repeating	New instance *
Repeating	Repeating	Same instance

* Note that this will create a new instance every time the rule is triggered. Select the "only if empty" option to create a new instance only when the value copied is different to the value in the current highest-numbered instance. This mode is like an audit trail - it gives a history of values for a field.

File Fields

Copying for file fields is supported from v1.2.0 of the module. New versions of source field files will be created and saved to the destination field when a change in file name, type, or contents is detected.

Enabling the Module with Existing Configurations

From v1.2.0, when you enable the module and existing configurations are present, such as following the creation of a project via copying another where the module is in use, certain configuration settings are automatically adjusted to reduce the risk of data being copied to an incorrect project. For example, it is not desirable for data to be copied back to a Production status project from a copy made of it for testing purposes.

For instructions that are enabled, and where the destination project is different to the source project:

Enabled? will be set to false, and
Destination project will be deleted (set to empty)

Limitations

Data may be copied from fields only in the same event as the triggering form.
Data may be copied to fields in a single event. To copy to multiple events set up a trigger/rule for each destination event.
Copying data occurs when a data entry form or survey page is saved. Copying is not triggered for data imports.

Configuration

Name / Description (Optional)

Optionally provide a name/reference and description for each copy instruction.

Enabled?

Check to enable the copy process. Uncheck to disable.

Trigger form(s)

One or more instruments for which the current copy process will be triggered.

Trigger condition

Optional: a REDCap logic expression that must evaluate to true for the current ercord in order for the copty process to be executed. Leave empty to always copy on saving the trigger form(s).

Destination project

The project to copy data to. Can be within the current project e.g. copying data to other events or fields.

Destination event name

Optional: the unique event name of the event to copy data to in the destination. Leave empty if the destination is not longitudinal or to copy to the first event.

Field containing destination record id

Field containing record id for destination project. The value from this field is used to locate the corresponding record in the destination project using the mechanism specified below. Record matching option
Options for locating a matched record in the destination project and for whether to create new 0. Match record id (do not create): Copy to record id saved to the field specified above. If no matching record found then do nothing.
1. Match record id (create matching): Copy to record id saved to the field specified above. If no matching record found then create one with matching record id.
2. Match record id (create auto-numbered): Copy to record id saved to the field specified above. If no value is present in the field then create an auto-numbered record in the destination and save the created record id to the field specified above. If a value is present and does not match a record in the destination, do nothing.
3. Look up via secondary unique field: Find a record with the value from the field specified above in the secondary unique field of the destination project. If no match is found, do nothing. (Note: it is assumed that the secondary unique field is present in the first event.)

Data Access Group option

Select how the DAG of the copied record should be utilised.
1. Ignore: do not set or update the DAG for the record in the destination project.
2. Include DAG in copy: the unique DAG name for the source record's DAG will be included in the copy. Destination DAGs must have matching names for the copy to be successful.
3. Map source DAGs to destination DAGs: specify the destination DAG to use for each source DAG. Multiple DAGs in the source project can be mapped to a single destination DAG.

DAG Mapping

Utilised for DAG option "Map source to destination" only. Unfortunately due to a current limitation of the module framework branching logic does not work for sub-settings.
Do not enter settings here if no DAGs to copy or if DAG names match.
Source DAGs not listed will be ignored and there will be no DAG assigned in the destination.
Mapping multiple source DAGs to a single destination DAG is perfectly legitimate...
Mapping a source DAG to multiple destination DAGs is not. The last one wins.

Copy fields

Pairs of fields mapping the source to the destination.
Select the "only if empty" checkbox if you want the copy to occur only for an initial value in the source field (i.e. copy the value only when the destination field is empty).

Example

This example illustrates a few things that the module facilitates:

Copying data between fields in the same project
Setting the Form Status automatically (in this case using a radio field, but using a calc field is an alternative).
Setting the record's DAG automatically by using a text field with @CALCTEXT() to generate a valid unique DAG name. @CALCTEXT(if([record-name] - rounddown(([record-name]/2),0)*2=0,'even','odd'))
