From the SC changelog:
[I]- Implemented the support to recovery tables fields name with dot.
- Correction on data recovery for sc_select and sc_lookup macros.
- Fixed problem in the criticism of existing records in the form application with composite key.[/I]
Are you sure you are using proper terms?
By “recovery” you mean “retrieval”?
What does “criticism of records” mean?
I’m not native english so I could be wrong, but to me it seems you’re often victim of false friends (e.g. your usage of “inform”)
