Hi Sreehari ,
FM PRICING is for viewing conditions applied for a particular document , i.e it gives Transactional Data.
Say you provide COMM_HEAD_I-KNUMV with a KNUMV ( Number of the document condition ) related to particular document (eg. Billing Document ) and it will get you all details in TKOMV table.
For viewing Pricing Procedure related detail you need to use VK11 only reason being Pricing Procedures consists of creation of Custom Tables ... during their designing. And I guess there is no standard FM for retrieving all these Configuration details.
