How Many days to Update PO Number in Finance document

Dear All,

I just want to double check something from you experts. Here is my issue. In our SAP system, we always record Customer PO number in the order document we create for them. This ensures that PO number appears on the invoice we create for the customer.

But, unfortunately, this numer does not show on FBL5N, so customer rejects the statement of account we send to them. We have asked our support to add this information to the header of Finance Document created for invoices, so that it can appear on FBL5N. They says this will take 21.5 man days to realise this. Even without being a SAP consultant, this looks to me too much. Can some one tell if this number is realistic or not ?

Thanks for your assistance.

    The effort estimation depends a lot on the complexity in your system, which is hard to evaluate without having access.

    Sometimes it happens that the business expects that a certain change should be fairly easy and could be delivered in no time, when it is not exactly the case, because it could impact other processes or system activities.

    In such cases I explain to the business the reasoning behind and try to provide a more detailed estimate, so that they can see what is included in the time and effort estimation.

    If I were in your position, I would request from the person who gave these 21.5 man-days to list by activity and resource how this calculation was done and why it is higher than I expected.
