Problem with BOM usage

Hi,

Due to client requirements, i have created a new BOM usage type "X".

At OS21, i have set the default as "relevant to production".

Defined order of priority in OS31, and assigned to plant parameters through OPPQ.

In OS30, created new application & assigned to production order types.

The Problem is iam able to make use of this BOM in a production order, and iam not able to explode it through transaction CS12.

When i explode it through CS12, the message i got is mentioned below.

E: to XCPPEDLJ31-DEMO4/IN10/ZP01 no BOM is available

Message no. 29514

Regards,

K.Kumar.
