Easy Cost Planning Error.

427 Views

Hi,

Iam having some issues creating a costing model and derivation rule to it.

1. created a characteristic using CT04 with charac group.

2. assigned to the costing model - CKCM

3. clicked on the derivation rule (template) - The issue is i get an warning message - the reference object can now no longer be changed. I selected WBS reference and then it takes me to the derivation rule definition. I defined the derivation rule saved it.

When i try to use it in CJ20N through planning forms nothing happens and when i go check it in CKCM the derivation rule is vanished.

Could you tell me what is going on here.

Am I missing any configuration or Why do i get the warning reference object can no longer be changed. My gut feel this is causing the problem. One more thing, i cannot change any of the existing costing model's derivation rule.

Could some one help me with this? Appreciate it

Regards.
