Hi @lececere,
Yes, Component is a separate hierarchy level in the Project dimension. If you do not have similar components across projects, then this solution works perfectly.
However, if you have the same components in several projects, then you may import Component also as a separate dimension using the same JavaScript code. In that case, add one more line to the advanced settings dimension = true to enable custom field import also as a dimension.
[jira.customfield_eazybicomponent]
name = "Component"
data_type = "string"
multiple_values = true
split_by = ","
dimension = true
javascript_code = '''
issue.fields.customfield_eazybicomponent = issue.fields.components;
'''
