Creating Physical Inventory Documents using batch job in WM

We use transaction LX26 to create the physical inventory documents for the storage bins and the materials therein. and the new PI dates are proposed based on the cycle count indicators configured.

We want to automate the creation of physical inventory documents using a batch job. How can we achieve this?

I understand that the program RM07ICN1 generates PI documents only when materials are managed at IM levels and this does not work for WM. Is there any other standard program which can be set up in batch to create the PI documents for the materials at WM level? If there is something then please let me know details....

Thanks,
