Subject [jira] [Commented] (OFBIZ-10953) have CurrencyDimension have a dimensionId that is based on the natural key
Date Thu, 06 Feb 2020 11:26:00 GMT

    [ https://issues.apache.org/jira/browse/OFBIZ-10953?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17031495#comment-17031495

Jacopo Cappellato commented on OFBIZ-10953:

Unfortunately it is not desirable to use uomId (i.e. the natural key) to populate the dimensionId
(i.e. the primary key of the dimension table): in fact, based on the update strategy adopted
for the dimension table (type 1, type 2 etc... as described in "The Datawarehouse Toolkit"
book) the CurrencyDimension table may contain several rows with the same uomId as this is
important for properly implementing drill-up and drill-down reports.

>          Issue Type: Improvement

>    Affects Versions: Trunk, Release Branch 17.12, Release Branch 18.12
>            Reporter: Pierre Smits

> Currently the record sequencer (delegator.getNextSeqId) is used to determine the dimensionId
for the CurrencyDimension. This is unnecessary as the uomId from the UOM table can be used
for currency.
> It also makes it easier to set the foreign-key in fact tables by generating it based
on the date provided, than by retrieving the dimensionId based on a retrieval through the
getDimensionIdFromNaturalKey service.
