Hello Sonia
Pricing Procedure is determined by Sales Area+Customer Pricing Procedure+Document pricing Procedure
So your quotation pricing procedure will get determined accordingly....which is Sales Area for which you want the quotation to be created for...Customer pricing procedure field which you can find in the Customer Master and Document Pricing Procedure which you can find in the Document Type of the Quotation that you are using.
Check the Pricing Procedure determination in T-Code OVKK to find which pricing procedure is assigned to your Quotation Document Type.
