Hello Guys
Please refer the steps below to rectify the case , status for the query appears answer assumed.
The error generally means that the document status is incomplete in GTS and this can be checked in log under technically incomplete document log.
Based on the log i.e. suppose you get a log saying the partner type is missing. Then goto your ECC system and re trigger the missing partners. So once the missing partner is retriggered , the documnet needs to be triggered again to get the latest status on document.
To trigger the document from ECC you can goto /n/sapsll/menu_legalr3 and trigger the document.
The above activity can be done for missing vendor master , customer , bank etc and transcational documents as well.
Hope this helps.
