Sizing Formulas
The sizing formulas are used to calculate the table sizes during folder validation. In fact, on folder validation, the table is sized considering that it will store a number of lines equal to a maximum of the following two elements :
The number of records in the table dictionary, if one has been entered.
The result of the sizing formula
The number of records in the dictionary is updated if the result of the calculation is greater than that entered in the record. Thus, when the table is validated from table management, the table is sized by the number of records found in the dictionary.
The formulas can use the sizing elements. These elements ha a value defined in the folder parameters.
