A Really Basic Issue : InfoObjects

Question

Hi All
This is a fundamental basic question about inofobjects.
I have recently extracted a table into a new DSO using a custom extractor. on the BW side I created 4 new Z inofobjects for use in the DSO. (say Z1 to Z4).
I have also enhanced a standard extractor with one new field and that field can be used to join to field Z3 above. However the data set will be much larger than that of Z3 in the DSO. This newly extracted field will go into another DSO which I am about modify.
The question is should I enhance this DSO by adding inofobject Z3 or create a new infoobject. What is the impact of the 2 options. Is it worth using Z3 as a template or even a reference infoobject) ?
Am I making this unneccesarily complicated and worrying over nothing.
Thanx

Answer 1

If the definition of the source data is the same then it is unnecessary (and even makes the datamodel too complicated) to create a separate info object.
Let's say if you have a country data field and currently using it to map it in Z3 info object in a ODS for contintent 'Australia' data, it will only have a couple of values for your Z3 (country) info object. If you are now going to populate another ODS that holds data for the rest of the world, you would still use the same country info object (as the definition of the data is the same, only the number of different values increases).
