ACF CMM migration gives Memory Access Violation error
ACF CMM migration gives Memory Access Violation error Problem Description (Be as specific as possible):
When migrating structures from Ideas to NX using CMM we have suddenly started to get errors "Internal Error: Memory Access Violation" and "Failed to create NX part". This is happening when the migration is made on the ACF target part. Found an
existing PR 1991975 which is describing the same situation - still in Open state.
Customer is currently using:
NX8.5.3.3 MP1
CMM8.5.2.1
TC 9.1.2.5
In February Customer upgrade the whole global PDM to:
NX9.0.3
Ideas 6.4
TC10.1
Immediate fix for NX9 is required. We cannot wait one more year to start the full transition to NX. We have just been able to build all the costly tools required to migrate the Ideas structures to NX with huge efforts and now we are facing this catastrophy.
ACF Migrations is working with CMM8.5.2.1 and NX8.5.2.x.
Since NX8.5.3.x ACF Migration is broken, this problem has been reported to development already in PR 1991975. Siemens PLM believes that the problem you reported where "ACF CMM migration gives Memory Access Violation error" will be resolved by code changes made to the release of our product NX version 9.0.3.mp5.
