Capacity check in production order & planned order

Hi,

I am trying to do capacity check in production order / planned order but it seems the system doesn't check the remaining available capacity on the work center instead system checks againts total available capacity.

We are using scheduling type : only capacity requirement.

When I created planned order for a particular date, with capacity requirement is 10 H, system says the capacity is available, but if i go to capacity analysis in planned order i see there is overload because I only have 9 H remaining (Total available capacity is 100 H but has been reserved for 91 H)

In IMG (definie checking control), I have activate capacity check and maintain SAPSFCG013 as overall profile.

I also maintain finite sheduling and capacity leveling overall profile SAPSFCG001 in production scheduling profile.

Please advise

Thank you
