Physical inventory

dear all,

we are working on split valuation. we are now doing physical inventory. i have create documents through mi31 with plant and stores location. out of that some materials are not include in Phy inv docs. for those materials i check split valuation which is available. also i have check material movements that was also found.

so my question is if every data required to create physical inv doc is ok then system does not create document for these items.
