Hi Helmut,
Pity the note is not applicable for your systems.
If the standard HR idoc from ECC crashes in GTS in standard SAP code, without running through any customer Z* code - your developer can confirm this - it is appropriate to raise this as a support ticket with SAP directly.
If you solve this one way or another, please let us on the forum know.
Best Regards,
Branio
