Inhouse Repair Process Implementation effort in CRM and ECC (rough estimation)

Hello,

Inhouse Repair process should be implemented (complete process from repair return over loan delivery, loan pickup to quality notification

Does anybody know what might be the implementation effort in both CRM and ECC as a rough estimation.

In CRM the relevant item categories and action profiles with actions seem to be already available. But in ECC there is for sure nothing available such as transaction types, item categories)

I would guess 18 days but I'm not sure about it.

Thanks in advance

Rainer
