Hi Joao Sousa,
Thanks for Quick Reply,
IF PO is created by Region wise Concern PO Value is Rs 50,000 INR , in this case 1st & 2nd Level of approval is not required directly 3rd level of approval will become First level Approval, and 4th level is second Level of Approval and finally 5th level is Third level of approval for that Purchase order .
Here only One Document Type we are maintaining .

Kumar
