S4 & BPC Data Duplication Isuue For May 2019

HI Experts,

We are currently experiencing a scenario in our RTC implementation where for the month of May 2019

we are getting YTD balances from S4 (which means in May 2019, we have data for JAN, FAB, MAR, APR 19).

Now, as part of data migration activities we would like to load PER May 2019 data, but this will cause

the total transactional data for MAY 2019 to be doubled (in reality 6 times the actual results).

To resolve this issue we would like to understand if there is a way to filter out S4 data (INPUT Audit ID) for the month of May 2019 in BPC?

This filter should filter out the S4 (MAY 2019 YTD data) in Analysis Office reports.

Will really appreciate if you can provide some guidance on this issue.
