Regarding Match Approval Level.

 Dear All,

I tried to create Purchase order in two ways

1)  First created a Purchase requisition and then created Purchase order using 'Auto Create' option. In this case, for a particular item, Match Approval Level (in Shipments) defaulted was '4-Way'.

2) Secondly created Purchase order without creating Purchase requisition. In this case Match approval level defaulted is '3-Way'. (Note: For the same Item).

I would like to why there is discrepancy between the two?

Note: As far as my knowledge goes Match approval level is defaulted from one of the below

a) From Item master

b) Purchasing options

c) Supplier
