Stock Coverage

Dear Users,

I have a rwquirement to be achieved by creating report in Inventory management.

The thing is To calculate moving STOCK quantity from the key date to last six months * 2. and the data stock Movements should only consider Shipments and Consumptions moving type on production orders.

Moving quantity is not the Total stock quantity.

It seems Moving quantity = Goods Issued + Goods Receipt. Is this correct? I don't know how to calculate Moving quantity.

Does this mean that Goods Issued and Good receipt are two fields in SAP system??

Regards

Syed
