This is my first post and do pardon me if I've posted in the wrong category.
Currently, I am implementing a Third-Party processing where I am the middle man, receiving customer PO, and then generating a new PO to my vendor, so that vendor will ship the items directly to my customer. However, vendor will bill me accordingly where I will then bill my customer too.
However, before PO is generated, I have to receive 6 months rolling forecast from each of my customer, total them up, and generate a 6 months rolling forecast for my vendor to facilitate their own planning.
May I know which module of SAP can be used to perform all this forecast operation, coupled with MRP and MPS, and then generating a totaled-up forecast for my vendor?
Would appreciate if there is a step-by-step guide too.
Thanks in advance for your help.
