How can I customize template in ‘import financial planning data’

Hello everyone,

I’m struggling to find a right solution about template maintenance in S4HC 2005.

The business want to change and add some fields those exist in some documents in this financial plan data. How can I configure the relevant fields into these template, thank you!

I have find some helps from S4HC, but it seems not helpful to me.

Regards,

Kudi
