Problems with file extensions when saving files using Archivelink

Hello.

When saving .jpg and PDF files using Archivellink Use CALL FUNCTION 'ARCHIV_CREATE_DIALOG_META'.

When using the corresponding function, if there is no data in the TOACU table,

the file extension is saved in *.

File extension * >> Archive link does not open

TOACU is an archive link custom table.

When I search, I think the data set by IMG setting is saved.

Why is there no data on that server?
