Field help (ABVFLDDEC)

When the synchronization rule is of the type (1,N), this field from the principal table is used, which is supposed to be dimensioned (several occurrences).

The extraction algorithm is thus used to access the data in the grids stored in the principal on-line table. The principle is as follows : there is the possibility to vary the system variable index from 0 to N-1, N being the dimension of the triggering field and for each value :

• the line condition is evaluated (which can depend on the variable index).
• if it is true, all the destination formulas are evaluated to obtain the values for the fields to be updated.
• the record in the corresponding datamart is updated.
