When accessing the data of a parameterized table, you often require access to data in all the instances of the table. By defining a table to hold the data parameter values, you can relate this information in your data access. This relationship can be coded explicitly using a FORALL statement or implicitly using a tool interface. You must have DEF_PRM access to the source table to define a subview of it.
After entering the initial Table Definer screen described in Accessing the Table Definer, you must change the table type field to PRM. When you press Enter, a screen similar to the following appears.
In the Source field, type in the name of the table that is used as your source of data. The source table must already exist and it must be a parameterized table of one of the following:
A parameter table is a virtual table, meaning that its data is extracted from dynamic source information. The
NUMBER field of the parameter table depends on the following:
Therefore, since the values in the NUMBER field are dynamic, it cannot be used in any meaningful way and should be ignored. For example, the
NUMBER field for parameter instance A has a value of one but on the following day the
NUMBER field (for parameter instance A) could equal 2 because a new parameter instance is added.
