I have dont all the setups regarding and Internal Requisition is creating here using java form and then whole IRISO Cycle is also activating, but here while i am trying to do the same with the iprocuremnt so it is always creating the Purchase Requisition. I have also setted the Sourcing Rule and Source Organization is also settled at the Org Item Level. I am not getting y this is happening. As for as the Profile option is concen so it is also gets Automatically detect
