Hello Vanessa,
In standard Business Central, posting a Purchase Invoice should create a Vendor Ledger Entry in addition to the relevant G/L, VAT, Item/Value Entries; Microsoft explicitly documents that the vendor account is updated when a purchase document is posted, so a Posted Purchase Invoice with no VLE is not expected standard behavior. First, search Vendor Ledger Entries directly using the posted invoice Document No. / Vendor No. / Posting Date, then compare the Transaction No. of the related G/L entries because Find Entries alone should not be the only verification; also note that your screenshots appear to show different document numbers/dates, so confirm they refer to the same transaction. If no VLE exists, check whether you have any customization/event subscriber around purchase posting (Purch.-Post, vendor posting, IsHandled, etc.) and review telemetry/event logs from the posting time; if there is no customization involved, I would treat this as an abnormal/incomplete posting and raise it with Microsoft rather than manually inserting a Vendor Ledger Entry, as manually creating ledger entries would break the accounting/audit relationships.
