Planing into ACDOCP: Options without BPC and SAC Licence

Dear SAP Experts,

we want to offer a Financial Planing BI Solution for our customers in S/4 in order to plan into ACDOCP.

The challenge is:

• The classical "non ACDOCP " planing transactions (KP06, KEPM...) could be shut down in the near future. Is this assumption right?
• The functionality and user friendliness of the Fiori App "Import Financial Plan Data" does not match classical "non ACDOCP" planing transactions at which many customers are used to.

  https://fioriappslibrary.hana.ondemand.com/sap/fix/externalViewer/#/detail/Apps('F1581')/S14OP
• The cost of BPC and SAC for Planing ACDOCP is too high for many customers.

Could you please recommend an ACDOCP planing BI Solution, which

• offers similar functionality to classical "non ACDOCP " planing transactions
• can be implemented easily
• is standard in S4 and does not Require BPC or SAC licences?

Thank you very much for your support!
