* The reason is to save time and reduce dependency on purchasing department that usually focuses on core purchasing tasks.
* For example in the classic scenario, a purchase order is generated in ECC. For any changes to PO, we need to contact purchasing department.
* So still we have a dependency. But in ECS, we can edit the PO in the SRM system itself and changes will be replicated to ECC. So we need not contact purchasing team and the burden on purchasing team for such requests will totally be eliminated. So for low spend purchases, we need to depend on purchasing department at all
