The Conditional Split looks like the following for SCD TYPE(overwrite). There are numerous ways in which you can implement slowly changing dimension processing in SSIS.

So quite often people make use of alternatives like using a combination of lookup task with conditional split to do the SCD processing. There are multiple ways to implement that in SQL Server and the easiest of those is using Slowly Changing Dimension Transformation in the data flow task of SSISSCD Type 0 (Fixed) This type is the least frequently used as this type does not accept changes and is fixed after first time insertion it what is the best way to implement the type 2 dimension in SSIS from the following options: 1. using merge statement. 2.using SSIS SCD component 3.using lookup, conditional split(custom way to implement it). Are there thoughts on which path would be best to take in terms of which tool to use for Type 2 SCDs?Makes it a bit slower to develop. Im curious how the Microsoft SCD transform performs in this regard. To override the in-build SCD transformation in SSIS dataflow, I used checksum values of columns and a lookup. Below is the process.

This transformation is used to implement Type 1Yes, but in that case you dont have to use SCD transformation, you can do it by using Lookup transformation, and build your custom logic. To override the in-build SCD transformation in SSIS dataflow, I used checksum values of columns and a lookup. Below is the process. I need to implement the SCD type 1 in TargetFacttable. In last post we discussed about Implementing Type 1 SCD in SSIS using Slowly Changing Dimension Transformation and u can find the same here. I am capturing all delta Loads in SSIS by using lookup component combined with conditional split to compare source(CRM) and destination(STAGE). The Conditional Split looks like the following for SCD TYPE(overwrite). SSIS : Method 1- Using two lookups instead of SCD (Slowly Changing Dimension ).SSIS : 200 Type set to A.500 PORT/EPRT (Active Mode/Extended Active Mode) is not supported.

A type 2 SCD can be implemented similarly with lookups, only this time we require 3 lookups.Another alternative to the SSIS SCD transform is to use the free, open source, third party SSIS Dimension Merge SCD Component.
