Create Phys Inv Doc for Cycle Counting - Clarification

Hi Friends,

I have an issue in creating a physical inventory document for all materials in a plant.

I have more than 4000 materials in my plant and more than 400 materials has stock. Most of the materials which are in stock are A class items.

When I create a Phsical Inv doc I have only 22 materials for which the a screen is created for creating a batch input session. The planned dates are for the last 1 week.

How does the system recognise that these materials are required for cycle counting in this week?

Thanks for your help.

Thanks.

Best Regards,

Narayana Rao.
