SAP Error Message - Details

• Message class: GG - Messages for FI-SL customizing

• Message number: 820

• Message text: Maintain the alternative source

What causes this issue?

You have established that the processed field group has to be updated.
However, you have not established whether the field group is also to be
assessed or distributed internally (by defining sender and receiver).
If you do not wish to allocate internally, you must enter an
alternative source for the data to be written.
Example: In Special Purpose Ledger, the transaction currency can be
updated without being assessed or distributed directly (internally).
Normally, you would select the group currency as the alternative source
for the data. In this case, the group currency converted into the
transaction currency unit is then updated in the transaction currency
fields.
