Infoset Nav Attribute problem

Hi all,

I created an infoset containing activities cube(0csal_c01) and 0cust_sales. See the attachment please.

What I want to do is joining 0crm_Salorg in the cube and 0salorg of 0cust_sales but I can not do that because their format are different.So I activated the attribute salorg of 0crm_salorg to join 0cust_sales__0salorg.But it does not appear in the infoset since 0crm_salorg is a time dependent characteristics.

Adding 0salorg ruins my modelling(or I could not achieve to model this in infoset) What can be done to join 0cust_Sales__0salorg with the cube?As you see the key field 0salorg is free and this affects the values in the report.
