There are two main ways to expand a Payroll or Time Schema and each has advantages and disadvantages over the other. One is to run the programs for at least one individual with the Log Display option selected. The other is through transaction RPDASC00 which allows for the option of 'exploding' the schemas down as far as individual steps within a PCR. Expanding or exploding a schema can be extremely useful in route-causing issues or locating configuration which may need to be copied or maintained.
The main difference with Displaying the Log of a payroll or time processing, is that RPDASC00 explodes the entire schema (to whatever level is chosen) -not just the part relevant to a particular employee. This is particularly useful in locating such things as wagetypes and PCRs which will not necessarily have been processed.
Layout also differs being more the traditional table view format rather than the tree view format presented by the Display Log. However, since this is an expansion of the whole schema, there is exact reference to line numbers and sub schemas (excluding any lines which have been commented out), making location and editing of a particular point within the schema easier.
If the options are selected such that all schemas and calculation rules are expanded, a search for (e.g.) a particular wagetype will return every possible occurrence of that wagetype within the schema. This allows tracking of every stage of processing and may help to reveal errors in PCRs, configuration which can be duplicated and modified, etc. The disadvantage of this way of expanding the schemas is that any wagetypes which are not processed within the schema but are just read in and posted to a table, to the RT for instance, will not be found.
When running both Time and Payroll schemas either in real or simulation, there is an option to Display [the] Log.
If this option is not selected but the schema encounters an error which prevents process completion, a partially expanded schema (down to the error point) will be displayed. If the schema executes successfully, there will be no Log displayed.
With the Display Log selected and the program executed, the respective schema is displayed for the employee(s) being processed. In this instance the schema displayed may not be the entire schema. Only those sections which have been processed in relation to the employee(s) selected are shown. This is a distinct advantage when tracing, for example, a wagetype through the schema to ascertain how its value in the RT relates to its initial value, or why it has not been processed or output.
The other major benefit of this way of expanding the schema is that actual data and meaningful values can be followed through making errors easier to identify than when using the exploded schema view via RPDASC00. Since the expanded views of PCRs show only those steps through which any one employee has been sent, errors in calculation (particularly if steps within a PCR are printed out) can very easily be identified.
The disadvantage of expanding the schema in this way is that any wagetypes which are hardcoded into PCR's as assignment wagetypes and then written straight out to the RT without any further processing, will not be found on searching. They may be located in the RT but it is more difficult to ascertain how their value was derived.
This Schema is expanded within a tree view which shows clearly the relationship of processing steps to the various parts of the schema (Gross Payments, Loans, Benefits etc). The main immediate difference between payroll and time schemas at this stage is the at the former displays by payroll period and the latter by day.
