Workflow for Budget Exceed in PR
We have budget check at Purchase Requisition creation and also we have release strategy (workflow) based on total PR amount and cost centre. If there is no sufficient budget, then SAP throw an error and stop creating PR. This is our as-is process.
Now I want to incorporate workflow with budget check. I want- if there is no sufficient budget in selected cost centre, it will go for approval (request for budget) to some designated authority. When sufficient budget is entered then PR can be released. This way we can record the request for ad-hoc budget and its approval inside SAP which we are doing out of SAP at present.
Is there any way in SAP standard to meet this requirement?
