What is RecId?
The RecId is a unique
field in every table, used as an identifier. Every row in the system can be
guaranteed (in theory) to have a unique RecId. RecIds can be negative, and
their value can change due import/export operations. Due to this, it is not a
good idea to use RecIds as foreign key references to other tables.
What is the
difference between a RecId and an Id?
The kernel generates the RecId while the Id is generated by the application.
