For Sales Projects, either Customer project with sales integration or Multi-Customer Project you can only use the JEV type 00088 – Manual Entry for Sales Documents.
The JEV type 00047 only posts in the General ledger without any subledger involvement.

If you just need to reassign costs or revenues to a Multi-Customer project use Journal Entry Voucher type 00088 – Manual Entry for Sales Documents and screen variant 634 - Man. Write-Up/Write-Down for Sales Doc.:

1. Go to the General Ledger work center.
2. Select the New Journal Entry Voucher common tasks.
3. In the new screen, select Journal Entry type 00088 - Manual Entry for Sales Documents.
4. Select the Screen Variant 634 - Man. Write-Up/Write-Down for Sales Doc.
5. Maintain the line items as needed, crediting or debiting the Multi-Customer Project in one line item and the respective cost object (for example a Profit Center) in the other line item. 
6. Press Simulate.

This time the simulation of journal entry posting is possible.
