How to read field value from dynamic field name into a SmartValue in Jira automation

[MARCO EBERHARD]

I have a dynamic Field name in a Smart Value {{VarField}}

It is no problem to set a value using  "Edit issue fields" Advanced like this:

{

  "fields": {
         {{VarField}}: {{VarValue}}
         }
}

Until now, I struggled with doing the opposite:  Reading the field value from {{VarField}} into a SmartValue {{VarValue}}.

How can I do this?

Hi @MARCO EBERHARD 

What do you mean by "dynamic field"? Is it a custom field which you have created inside Jira? If yes then you could get it using the smart values https://support.atlassian.com/cloud-automation/docs/jira-smart-values-issues/#issue[.custom%20field]:~:text=the%20issue%27s%20reporter.-,%7B%7Bissue.%5BCustom%20Field%5D%7D%7D,-Similar%20to%C2%A0

If not, kindly explain further.

Hi @Alex Koxaras -Relational- 

I have several custom fields following a standardized field name scheme.

In the automation, the field name I want to read out is calculated. So {{VarField}} might have one of the following values:
- Field_01
- Field_02
- Field_03
- ...

{{issuel.Field_01}} is working but {{issue.{{VarField}}}} does not work.

if needed, I could also work with customfield_xxxxxx instead of Field_yy

Thanks, Marco

How do you calculate the VarField? Using smart values inside the "create variable" component?

@Alex Koxaras -Relational- 

I have created a lookup table containing around 20 entries with a key and the FieldName as value.

Key                   Value
Key_01              Field_1
Key_02              Field_2
...

Then I Branch for each {{Table.entries.key}}  --> into {{ActualKey}}

Then I get the field Name (Crate Variable) {{Table.get(ActualKey)}} --> into {{VarField}}

Now, I want to read the value of the field that's name is in {{VarField}} into {{VarActualValue}} --> here I struggle.

Then I want to do some calculation wit {{VarActualValue}} into {{VarValue}}

Then I Edit issue Field "Advanced"

{

  "fields": {
         {{VarField}}: {{VarValue}}
         }
}

To write back the new value is working perfectly.

Thanks.
