Getting error while changing from Batch Level from Material to Plant

Hi All,

we have copied one client 600 to a different client 601.

600 client is showing below in OMCT.

Batch Unique at Plant level

But 601 client is showing --> Batch unique at material level.

Then i tried to change from Batch unique at material level to Batch Unique at Plant level in OMCT

But i am getting the below error & not able to change this.

Error --> This type of conversion is not yet implemented

Please advise how i can solve this issue.

Thanks
