If you are missing posting journals, you need to be aware that if you are expecting posting journals from a statement

Xtendlink needs to be setup to produce these, this is done on bank account level

Edit the bank account in Xtendlink and set the fields as the following screenshot, and click save.

Posting journals are created when Xtendlink receives a statement, so setting this up will only work forward going

If this is already setup the way it is supposed to be, please look in your import log in AMC-Banking, perhaps the posting journal received from Xtendlink has not been processed, if you find it in the import log, click process/reprocess

this should either produce the missing posting journal, or reveal why it was not produced in the first place
