ePOS parameters can be assigned to the value stock of Listboxes, Comboboxes and the columns of tables to fill the selection of these dialog objects.
Since it is about a list of values in each case, an indexed parameter is required. The output always occurs from a defined start index (fixed or as a parameter too). The following options are available:
A once indicated simple or PG parameter.
A not indexed parameter of a once indexed parameter group.
A once indexed parameter of any indexed parameter group. The index parameter groups is seen as fixed here and the indication of the parameter is used.
Examples:
Length[1] | → Listing all lengths |
pos[1].Designation | → Listing the designation of all positions |
pos[StartIndex].ID | → Listing from the StartIndex index. |
Article[i].ExportSurcharge[1] | → Listing all export surcharges of the article i |
Repeatedly indexed parameters or parameter groups are not permitted.
The acceptance of values for all dialog objects apart from the table is ended by the first array value being in the EMPTY or UNDEF state or by the definition length of the array.
For tables the allocation takes place per column, which means the number of values in the columns are independent of each other. The end criteria here is an array value in the UNDEF state. If the state is EMPTY, an empty cell is created.
The parameter can be dragged into the respective field in the property window with the help of the input assistant using Drag&Drop. The value "1" is automatically suggested for the index but this can be changed at will.
