I see where I can update the vendor posting group on the Vendor screen. However, what happens to current open purchase orders and invoices? I'd like the change to be reflected on the outstanding documents
add on to previous comments, this rule applies to other situation as well. for example, if you change setting for item card, the change won't be reflected on an open SO containing that item. you need to delete the line and recreate so BC pull in the new value. this is something many users are not aware of and deserves attention.
Valentin is correct, this system only obtains master data when it is used.
For example, if Vendor is selected on the Purchase Order, the Vendor master data at that point in time will be automatically filled in on the Purchase Order. The same goes for other master data, such as Items and Customers.
Even if you update the master data, it will not have any impact on the data that has been created.
You now have two options, one is to delete the invoice and recreate it, the other is to manually modify the posting group.
For the second method, you can make small customizations to do it in batches, or use Configuration Package.
If you change any field on the vendor card, including the vendor posting group, the changes will not affect existing open documents. The changes will only come into effect when you create new documents going forward. This applies to all master data in the system, not only to vendors (i.e. you make a change on the item card, items on open purchase orders will not be affected with this change).
In your case, the current open purchase orders and invoices will still have the old vendor posting group, you will have to change the posting group on those documents one by one as well.
Once the document has been posted, you can no longer change the posting group.
