Yes, “Copy Record” app can create a copy of record along with its multiple child records. You can select multiple 1..N child relationship when creating Zap_CR_Configuration record for an entity.

Let’s consider an example: Suppose we need to Clone an “Account” along with its related child “Contacts”. So you will need to create a “Copy Template” of “Account” as well as “Contacts”. Then within the “Copy Template” of Account…in section “1..N Templates”… select the Contact “Copy Template” that should be used when child contact is being cloned.
If “Copy Template” is not selected in “1..N section” then we pick the first template, we find for that child entity.

Copy Record App can clone record along with its child record. (e.g. Opportunity along with child: opportunity product).

You will enable the “Deep Copy” feature when:

1. You need to CLONE Child records which are more then 1 level deep.
2. Cloning of child records even with 1 level is giving time-out error.

“Deep Copy” is a check box in “Copy Template” record.

Yes, of course. There may be certain scenarios where there is a need to clone from 1 entity to another. Common examples could be:

• Cloning from Contact to a Lead
• Cloning from Case to Opportunity

For details on how to configure “Copy Templates” for these scenarios refer KB article: https://support.zapobjects.com/zap-copy-record/how-to-copy-record-from-one-entity-to-another/

Yes. You can set the date-time field of the newly cloned record with a default value.

– To enter a static date… use format: mm/dd/yyyy
– To enter a dynamic date… use tokens like: {{today}}+n where n could be any integer (e.g. {{today}}; {{today}}+5; {{today}}-1). These tokens output will be a date.

Yes. You can clone “Work Orders” along with its products, services, service tasks.

Please note that the “Copy Templates” settings for Work Order are slightly different then those of other entities (as we had to customize our cloning process especially for “Work Orders”).
