Description
This method loads database records corresponding to input values (records found in the t_s*** tables).
When nothing found in the database, a new record should be initialised.
Input values should also be updated with :
- identity fields (override input values)
- tc_Rowid / tc_ParentRowid / tc_Status
Annotation
This template can be used to implement the code for this method.
* Replace [MainTableName] with the name of the main table in the class dataset (no prefixes).
* This template assumes that the main table has an identity field, and this field is the only field of the primary index of the table. Replace [PrimaryKeyFieldName] with the name of this field.
* This template assumes that the table has one logical alternate key (a key that is visible and editable to end-users) with one field. Replace [LogicalKeyFieldName] with the name of this field. If the logical key contains more than one field, repeat the code with this tag for every field in the key.
* The run statement following [METHOD CALL] should not be copied literally, but inserted as a method call (run the method in your own component).
