Dear Taro,
I have assigned note to payee and its vendor invoice is reflecting in DOCNUMMR field of E1IDPU1 segment. This field is not getting updated in IHC payment order though. I have checked table IHC_DB_PN. This does not contain the vendor invoice information. IHC_APPL_PAYEXT_INPUT_IHC function module is not updating this information anywhere in table. Kindly let me know am I missing anything here?
Regards
Ashok kumar
