Planning Table for repetitive manufacturing

Hello,

We are using planning table for my current client. Here we have configured the planning table to be planned in the forward direction. This means, if we give a start date the system calculates forward, booking capacity in the forward direction and finally tells me when the complete order quantity is available.

But am encountering an issue, when i specify a start date; system automatically goes 1 day back and then calculates in the forward direction. I am not able to figure out why...

Any help on this would be greatly appreciated.

Sincerely,

Aji
