Condition Group1

Hello,

I have a condition type the value of which is depending on the value of Condition Group1 found in the Additional data A tab in the Header. When creating the sales Order I manually enter the value in the Condition Group1 field. The problem here is the value of my condition type is not getting calculated automatically after I manually key in the value of Condition Group1. I have to goto the condition tab and carry out the new pricing using the update fields to get the value calculated. Want to know is there any setting so that the value is calculated automatically else how can I default a value automatically for the Condition Group1 field.

Regards

Ravi
