CJ40 - Total Plan/Actual Consumption not updated

Hye,

In CJ40, First after primary cost for wbs element, i select the cost element and do detailed planning for that particular cost element, entering the material and quantities in Unit cost estimate.

After that , in my cost element the cost is getting uptated but Total Plan Consumption is still showin as 0.00.

Why so??? The Plan/Actual costs are displayed properly. But my Plan/Actual quantities i.e Total Plan Consumption and Actual Plan Consumption shows value 0.00?????

Any reasons for this and how does this quantity get updated in primary costs.

Regards

Manisha
