I have the following scenario:
DSO A --> DSO B
DSO A --> DSO C
DSO A is a common data source, whereas DSO B belongs to me and DSO C to another project.
Now, I need to delta load from DSO A to DSO B and the IT responsible told me that since DSO A has already been delta-loaded to DSO C the day before, and the indicator "Data Mart Status" has already been set.
Therefore I will not get new data records if I run a delta load from DSO A to DSO B. I do not really understand what he means.
However, logically this should be not the case for me!
Could anyone please clear my doubt? Thanks in advance.
