Hi

I would like to do a join with the follow 3 tables:

RequisitionHeader RH
JobHeader JH
PurchaseProcessHeade PPH

The joins:
-RH and JH on RH.field1 = PPH.field1
-RH and PPH on RH.field2 = PPH.field2

The current non-working syntax:

FROM
RequisitionHeader RH INNER JOIN JobHeader JH,
RequisitionHeader RH INNER JOIN  PurchaseProcessHeade PPH
ON RH.JobNumber = JH.JobNumber AND RH.PurchaseProcessNumbe = PPH.PurchaseProcessNumbe

Please help!!
