Change in multiple classification through ECR

Question

Dear experts,
We are using class type 050 (Reconciliation) for the classification of material BOM. I have assign two different classes (but same class type i.e 050) to a material BOM. but whenever I changes the classification data in reference to an ECR (date effective), BOM shows only one class in which changes were made.
Actually, it should show both classes with as on effective data.
please help me out
Thanks & regards,
Ravi

Answer 1

Dear Amber,
I want to change in classification values of one of the class assigned to a BOM. For example
BOM XYZ has been assigned class A & B. Class type is 050 (Reconciliation) for both class.
First characteristics of class A            Length                  Value - 100
Second Characteristics of Class A      Width                    Value - 50
First characteristics of class B            Specific Gravity     Value - 1.13
Second Characteristics of Class B      Density                 Value - 850
Now I want to change in the classification values of class A (Length 110 & Width 55) for the BOM XYZ with the reference to an ECR, effective from 15.06.2009 (if today is 03.06.2009). I am able to apply above changes in BOM with reference to ECR but whenever I want to see the effective BOM on 16.06.2009, it shows only class A, with new values instead of both class. It should show both class (A & B).
If you have the solution please explain.
Thanks & Regards,
Ravi
