Hi Stefan,
We're upgrading SAP E-Recruiting (standalone) to EHP8 and unfortunately running into the same issue at the SUM phase READDATA_EXP too. The source version is as below:
| SAP_BASIS | 740 | 0007 |
| SAP_ABA | 740 | 0007 |
| SAP_GWFND | 740 | 0008 |
| SAP_UI | 740 | 0009 |
| PI_BASIS | 740 | 0007 |
| ST-PI | 740 | 0002 |
| SAP_BW | 740 | 0007 |
| MDG_FND | 747 | 0005 |
| SAP_BS_FND | 747 | 0005 |
| WEBCUIF | 747 | 0005 |
| ERECRUIT | 617 | 0005 |
| ST-A/PI | 01R_731 | 0002 |
While we tried to follow the same approach of SEM-BW from the SAP guideSpecial Cases in Installation and Update | SCN,it didn't work because I guess SAP hasn't created additional product versions for ERECRUITING like SEM-BW in the SAP software catalog. So we can't simply get rid of the SAP ERP 6.0 in LMDB. Otherwise it causes the verification error in the maintenance planner util it's added back. By all means we're stuck and SAP Support can't help too much either. I wonder if someone has experienced the situation and could share any workaround or solution.
Thanks,
Jerry
