Unable to add document to DataSource

Hello everybody!

I have a question about adding documents to DataSources. We are using a BW 7.3 Level 0007:

For documentation porpuses we would like to add some documents to DataSources, unfortunately we are not able to do this.

1) When I double click on the DataSource an click on 'Goto' -> 'Documentation'; I receive the information 'No doc. object found for the override

2) When trying to add a document using the 'Documents' area in the navigation pane I receive following message:

To me it seems like that the Object Name is too long for the field. The full name would be: WSU002A PC_FILE (WSU002A PC_FILE)

Unfortunately this DataSource name is generated automatically and I cannot change it.

Did anyone of you ever experienced similar problems with adding documents to DataSources? With any other objects (Transformations, DSOs, etc.) there is no problem.

Thanks and regards,

Michael
