Planning Depreciation Simulation in ECC and Extracting to BPS .

Hello Gurus,

My client wants to use the Depreciation simulation report in ECC and want to use simulated data in BPS. They don't want to plan in BPS. I think there is no standard extractor which captures the depreciation simulation data for the future years like for next 20 years. Other then uploading by a flatfile into BPS, is there any other solution to capture the depreciation simulation data from ECC to BPS. Please advise. Once again thanks for your help guys.
