Error while changing BOM with change number

Question

Hi ALL, Please help me with followed error message, I am using ECM. I created ECR and converted to ECO and then released.
Object management record cannot be generated
Message no. 29046
Diagnosis
You want to change the BOM with the entered change number.
One of the following situations triggered this error message:
1. The indicator that allows automatic generation is not set for object type BOM in the change master.
2. The indicator generation only on initial creation is set for object type BOM
3. You are processing a change request.
System response
The system checks whether the indicator object management record will be generated is set in the change master.
If the indicator generation only on initial creation is set, the system checks whether the BOM exists in the system.
Procedure
If you are authorized to change the change master, execute the following steps:
For 1.)
Set this indicator for object type BOM or create the control record in the change master.
For 2.)
If the BOM already exists in the system and the generation only on initial creation indicator is set, the system can no longer generate the control record automatically.
In this case you have to add the object control record to the change master first, then you can change the BOM in relation to the change number.
For 3.)
You cannot generate any object control records for a change request.

Hi
With your question regarding changing BOM with change number  it looks lke there may be problem in defining the Object types,objects.Moreover whenever converted to ECO you need to enter into cs02 tcode for changing the bom with relevant change number and valid from date.
Hope this gives you a clear idea.let me know if you need anyfurther inputs.
