Multiple MBEWH records created when creating new material with BAPI

Hi,

I am using  BAPI_MATERIAL_SAVEDATA to create a material.

When Creating a brand new material, the BAPI will create multiple MBEWH records, which is causing to update Previous Period/Year Moving Average price to update in MBEW.

Any suggestion, why the BAPI would create historical data for MBEWH?

Thank you very much.

Oleg.
