Hi Aleksey,
Thank you for your reply. To clarify my second question: when we post a cross company code vendor invoice, we do not wish to split the A/P by profit center. One approach to fix this is to use FAGL3KEH to set a default profit center for the A/P GL account, however, that will not work because in other vendor invoices that are not cross company code, we do not want to use the default profit center.
You gave one solution which was to create a separate document type and exclude it from splitting logic. I suppose that is an option, however, it is not always possible to ensure users choose the right document type when posting the invoice. Maybe I can use a validation rule to force them if that is the only option to avoid the splitting.
If anyone has any further suggestions, I would like to hear them.
