I have 4.5 years of Experience in Ariba Technical Support for Buyer & Expense Module. Moved to Ariba Consultant profile, in Presales department. I would like to know the time frame of Implementing Ariba PTP, Travel & Expense, E-Invoicing, Sourcing and Contract module, each differently (ON cloud and on Premise,both). Also how much estimate time will it take to implement each module with ECC (for example SAP). If you have any guide or template that defines approximate timeline for implementation of above mentioned modules and its integration with SAP. Help will be much appreciated.
