Hi,
The requirement is not to use purchase requisition at all but to use purchase order directly.This needs to be linked to a workflow.
Also the approvals are required for PO's directly and not PR's.
In terms of the customzing, what changes are needed, also to override the settings for not using PR at all but only POs for approval, which user exit needs to be written, if at all.
In summary, workflow + PO without PR, how can this be done...Thanks a lot in advance.
