The original error relates to a specific date format : YYYYMMDD.
We are now working around this by simply using an alternate format, eg. YYYY-MM-DD
One could say to now ignore it, as a workaround is available.
However, this is unecessary coding for handling what is after all, the default date string format used in ECC.
Also confuses users/wastes time if you are not aware of the issue.
Plus ... it's not guranteed to work for all future requirements.
I'm asking our admin to submit as a bug to SAP.
Again ... I can't imagine we're the only ones affected.... be interesting to hear other experiences.
For the record:
