Liquidity forecast and cash position

Hi friends,

I'm trying to set cash position and liquidity forecast (FF7AN And FF7BN), after I applied note 2255996, in SAP Simple Finance, without success.

The settings performed are:

1. Activation of cash management and forecast in company code (trx OT29)
2. Definition of cash management accounts names (OT16)
3. Definition of grouping structures (OT17)
4. Range maintenance (OT20)
5. Planning levels defined (OT12)
6. Planning groups defined (OT13)

The tables FDSB for GL accounts, FDSR for customers and FDFIEP for vendors, aren't be filled after execute business transactions like purchase orders creation and so on.

In previous versions when this occurred, I execute the following programs:

1. RFFDDL00 / Program for Deleting Cash Mgt Data from FI/MM/SD/TR
2. RFFDKU00 / Transfer Open Item Accounts to Cash Management
3. RFFUEB00 / Copy G/L Bank Account Balances to the Cash Position
4. RFFDIS00 / Reorganization of Cash Management and Forecasting

When I run the last program (RFFDIS00) the system showed the message "Function is not available", like the attached picture.

Another way to fill the required data for the liquidity forecast, is executing FDFD transaction, but doesn't display data correction option, not like in older SAP versions (i.e. SAP ECC 6.0).

Somebody can use the liquidity forecast and cash position in S4Hana? Any help will be useful, thanks in advance.

Best regards,

Simon.
