Hi,
Please refer following for similar issue:
Distribution of Distribution modell error
During the ALE Model Distribuion, the Function Module MODEL_DISTRIBUTE is called and from within this FM a Remote Call is made in the RFC Destination (Target System) for the Function MODEL_VIEW_REPLICATE.
The possible reasons are:
a) Model View name is not specified
b) No Authorization to Create or Change the Model View in target system for the user id mentioned in SM59
c) The BAPI or Message Type involved in the Distribution Model already exists in another Distribution Model in Target system
d) Model is being edited by another user in the target system
Regards,
Azhar
