Cost missing after 222Q before 221Q

HI,

My client has done a MIGO for particular batch of materials and immediately done a 222q movement(By mistake instead of 221Q). To reverse the same 221Q was done by her. The stock is reveresed using 411 & 412 mvts to bring it to GNST but now cost doesn't flow in Amount LC column.

My question is 1) Can you do a 222q movement even before a 221Q is done?

2) What happened to the cost of the product ?why is it a zero in the Amount LC column.

3) Can there be a product or a stock with zero cost??

Thanks & Regards

Swathi
