no pricing procedure could be determined

Dear all:

When i create a sale order,system popup a error message "no pricing procedure could be determined" and the diagnosis says because no entry with Keys"SOr,SDch,SDd,A" exist in table 683V.but when i use t-code"se16" to check this table,error message is "Table 683V is not active in the Dictionary",what's problem with it?I'm sure the process thant create pricing procedure is correct!
