Sales Order: In completion Log for condition Pricing Procedure.

Hi 2 All,

Please provide your valuable inputs for the below.

We have multiple Sales Areas for One pricing procedure.

Now I have one requirement. and its statistical only

1) For one sales area  Business want one condition to be created,  without that condition fulfilled SO cannot processed.

what i am thinking to go in completion log.

But My concern is

1) If create condition & assign in Pricing Procedure, make it mandatory,.... is it apply's to all other Sales areas. if yes, then how to achieve this.

2) If in completion log need to be created for that Sales area (the same pricing procedure for other sales areas also), how to achieve this.

please let us know.

Thanks.
