Hi,
FYI we experienced the same issue on 5 different Hierarchy save processes after upgrading from 7.30 SP8 to 7.40 SP3, and applying SAP Note 1896070 resolved only 3 of them.
We still have 2 that fail the same way (with exactly the same short dump) and SAP's support is still investigating it, so I would strongly recommend you to test all Hierarchy save processes.
Hope it helps,
Sebastien Francal
