Loading transactional data before go live

[Former Member]

Dear colleagues,

In my actual project we have an unexpected and strange requirement wich is to load all the postings that they have done during the year before go-live in their legacy system (we are going live on may). Therefore we have divided the initial loading in two phases:

1) Classical loading (Balance GL-accounts,Open line items, Assets) at the date 31122008

2)Loading of all postings made during the first half of the year in their legacy system. In that point is when my doubts arise, specially regarding vendor and costumer invoices and their payments. How can we link the invoices and their payments? how can we clear them? and what about the partial payments?

If anybody has done a similar loading i would apreciate his help and guidelines,

Kind regards

Hi Marc,

Interesting Issue..

Its only theoretically that you are going live on may..

The time you are doing your first live transaction in SAP, you have gone live..

So, when you are posting the invoices and payments (AR and AP) you would do as you are doing the normal process (or)

Create a LSMW to upload the same on a daily or a weekly basis.

Because the posting date would contain the actual date of transaction, there should not be any issue in clearing..

Good Luck

The main issue is that the postings (numerical order and content) must be the same as their legacy system. From the point of view of the balance and p&L is not a problem. The biggest issue is the linkage between the payments and their invoices. For instance, imagine that we have a post in the legacy system of a partial payment of 2 different invoices, how can we link them? Cause if we upload just the postings with a lsmw we will have 4 open line items (2 in thw debit side and 2 in the credit side) with no link between them.

kind regards

Hi,

If you are talking about the part payment in the uploaded data, you cannot achieve that..

Had you wanted, you must have uploaded the data invoice wise rather than one final consolidated value.

If they can submit the data separately by transaction type, you can create new document types in sap or use an existing document. So that you know that all invoice that have been created through your LSMW jobs are rel. to legacy system.
