What if I make a change that requires a new attribute in a dimension table? |
If there is change in the data model with respect to a new addition of attribute to the EPM database, then you has to update the corresponding dimension job to incorporate this new attribute, otherwise the job will fail. If there is no source for this new attribute, then in the dimension job you can have a Default value assigned to this new attribute by using a routine that is delivered. |
What if I make a change that requires a new dimension in a fact table? |
If a new dimension key is added to a fact table in the database, then this is a change to the data model. Since the database has an additional dimension key for the fact table, this will result in changes to the ETL job. If this is a new dimension, then a new job has to be developed for this new dimension. Fact job must be updated accordingly with the correct dimension key and Corresponding SID population in the Fact table. |
What if I make a change that requires a new measure in a fact table? |
If a new measure is added to a fact table in the database, then this is a change to the data model. Since the database has an additional measure for the fact table, this will result in changes to the ETL job. Fact job must be updated accordingly with the correct measure getting assigned to the value that is either coming from the source directly or applying any logic that is required for this measure to be populated as per your requirements. |
What if I make a change that requires a new dimension table? |
A new ETL job has to be developed for this new dimension table as per the requirements. |
What if I make a change that requires a new fact table? |
A new ETL job has to be developed for this new fact table as per the requirements. |
