EBBR - Fixed Price Cost Based POC: Plan Cost is double what it should be

Hi experts, 

I person a billing WBS assigned to Revenue Recognition Key SPFC - Fixed Price, Cost Based POC. It's reasonably straightforward, I person 1 enactment bundle assigned and determination is 1 Purchase Order with 1 Line against this enactment package. I person received 1 invoice for the full magnitude of the PO. 

The planned costs connected the enactment bundle are precisely the aforesaid arsenic the invoice amount. When I unfastened the app 'Event-Based Revenue Recognition - Projects' and I look astatine the billing WBS some the Actual Cost & Recognized COS are the aforesaid and adjacent to the PO and I don't person immoderate planned COS. 

However, erstwhile I simulate the revaluation and spell to 'Explain Simulation' it is giving maine the close existent costs, but the program costs (could beryllium capitalised, POC relevant) is precisely treble my existent costs (and the planned costs successful the enactment package). So for the Revenue Recognition calculation it's saying it tin lone admit 50% of the gross alternatively of the 100% it should take. 

However I cannot find these program costs anyplace successful the system. There is nary accrual posting, I don't spot immoderate different program costs against the enactment bundle oregon billing WBS. The task outgo study app is showing maine expected costs arsenic well. So I don't recognize wherefore the calculation is abruptly doubling my program outgo amount. 

I couldn't find immoderate SAP notes erstwhile I searched, truthful I anticipation possibly determination present has already had this hap before?

Kind regards,
