Hi,
thank you all for answers. I'm familiar with RapidStart but this solution is not good choice I think. You have to import to General Journal (table 81) and post it manually. And yet you still have to indicate Balance Account No. because the amount entered does not balance.
XML port - It comes down to the fact that we need an XML structure anyway.
Therefore, I wonder whether to prepare this structure already in those systems and export. And then use the BC functionality for consolidation
