Hi Team ,
We are into a tricky situation and hoping some inputs.
We have two tables say A and B
They have a Common filed A.controlId and B.control ID on which that are Joined through a Outer Join
A is snapshot table and have only a Particular time range data current .
Fields in Table A will have Only one record say for an account number
Control ID
Created Date
Status
Account Number
Fields In Table B SCD will contain multiple records for an account with there status and previous status
Control ID
Created Date
Previous Status
Account Number
In table B the data is not pushed out on regular basis and we can have Null value for Previous status.
Issue is because Of data not available at times in table B , an account number can show null values for Previous status, we are looking for a Solution through which it should automatically take previous status values if there is null value's
Can this be done at Universe level ?
