I´ve read all the thread regarding this problem, but I still can't solve it.
My interface is synchronic from an Idoc. it goes through a BPM and then reaches a WebService
The messagge arrives perfectly but the ACK has the following error:
IDOC_ADAPTER - ATTRIBUTE_INV_SND_SERV
Unable to convert sender service R3_FPA_SALDOSBANC_BPM to an ALE logical system
