Delete a consol area in BCS

Hi

I am trying to delete a consolidation area in BCS because it is causing problems for the BW team when they are writing reports:

'Error Unable to determine consolidation are for data basis 01'.

I have deleted all of the tasks and methods associated with this consol area 02. The only things left are it's use by document type 22 and the Items master data. How do I delete these?

Example of use document type 22:

22 Elim Income Statement Month ( Document Type ) (02//1FB/BCS_INVCOM)

Example of use GL items

GL/500 Sales other bunits - between stat co ( Item ) (02/100/I0)

This consol area is set up in our dev client only but I need to delete it for reporting purposes.

Any help on this would be very much appreciated.

Thanks

Loretta
