RECN - Sales based settlement - Sales Report issue

Dear experts,

We have have created a contract with sales-based condition and a lease term of 09/14/2015 to 08/31/2019. There were sales reports that have been settled before through RESRSE (Particularly in period 12/01/2015 to 12/31/2015). Eventually, the management sent a memo stating that the tenant's commencement date should be 12/18/2015, so we have to change the start of lease term to 12/18/2015, as well as the validity of condition, reporting rule and sales rule validity.

Upon changing the starting validity dates of the items above from 09/14/2015 to 12/18/2015, we have noticed that the previously settled sales reports have disappeared but the FI document of sales based settlement were still in the customer line item.

Should we reverse the previously settled sales-based or is there other way to correct this issue? Looking forward for your best solution to this scenario. Thank you very much!

Best regards,

George
