Planned Order taking 6 months

Hi Experts,

I'm facing an issue wherein for a material/plant Planned Orders are taking more than 6 months time between the Order start date & finish.

Ideally it should have been 1 or 2 months.

The Planned Orders are created based on a contract(VA43).

The settings in Routing are fine & the capacity utlilization too seems to be ok.

Could you help in finding any other settings which i need to check.

thanks in advance,

rishi
