How to enhance 0ASSET_ATTR_TEXT

Dear experts,

I need to enhance the asset master datasource 0ASSET_ATTR_TEXT in BW with further (standard) fields of the same sourcetables. Does anyone have experience with this matter? Is it straight forward like other datasources, where you enhance the transfer-structure in SBIW and the extractor fills those fields automatically (with move corresponding?)

How about the delta? Everythings works fine afterwards?

Thanks

Frank
