Hi,

I have a requirement where a junction object can be used to associate set of objects to a particular object.

e.g. I want to create mapping between  A, B, C, D and X object. Either of A, B, C, D can be associated with object X. Instead of creating lookups for each object (A, B, C, D) I want to create only one text field which will store the SFDC ID (of A, B, C or D).

I want to know how feasible this data model is? What kind of problems i would face with this data model?

Thanks,

Lakhan
