Both my company and the developers we work with are having issues getting credit memos to import in iif files. Bills and other transactions work fine using the same format.

Here is an example. Trying to import this file gives an error "Error on Line 6: Can't record invalid transaction".

!TRNS TRNSTYPE ACCNT AMOUNT DATE NAME DOCNUM MEMO
!SPL TRNSTYPE ACCNT AMOUNT DATE NAME DOCNUM MEMO
!ENDTRNS
TRNS CREDIT MEMO Accounts Payable -0.51 11/28/2018 Sysco [removed] 
SPL CREDIT MEMO Dining - food & beverage:Raw food 0.51 20181128   
ENDTRNS

Thank you in advance for any assistance.
