PPDS Fixed Pegging Heuristics Enhancement to Add custom prioritization logic

[thamizhchelvan_gunasekara]

The objective of this document is the highlight the option available for  prioritizing the demand for fixed pegging like CTM demand prioritization and to highlight the option available for sort the supply available like supply sorting in CTM.

Fixed Pegging relationship between demand and supply can be used to know when and how the demand is fulfilled by the available/expected supply.

In some business cases the pegging report is mostly used to commit the customers or to monitor the order fulfilment pattern.

However the standard PPDS Fixed pegging heuristics do not provide much flexibility to sort the demands.

In order  to overcome this limitation SAP has provided the enhancement point (Badi  /SAPAPO/RRP_FIXPEG).

Demand prioritization in Fixed Pegging

PPDS Fixed pegging heuristics provide the option to filter the requirements (Demands) and receipts (Supply) to be considered for the planning run and also provide the sort profile for the requirements, however many fields labels like Order priority and ATP category etc. are not considered by the standard algorithm.

The demand/requirement sorting by ATP category and order priority can be done enhancing the BADI  /SAPAPO/RRP_FIXPEG.

This enhancement point have the method SORT_IO_NODES  and the parameter CT_INPUT_NODES. The parameter read the table /SAPAPO/OM_IO_PP_TAB contains the details of the requirements (sales orders, forecast and other demand elements)  like ATP category, Order priority, requirement date and time ( filed IO_TIME)  and order status etc.

By using this parameter required demand sorting can be done for fixed pegging creation.

The below example code  highlight the order sorting based on date and time and order priority.

Supply Sorting in Fixed pegging Heuristics

The standard heuristics provide the option to select the supply category can be used for demand fulfilment by using the filter for receipts,

Which is shown in the below screen shot.

The receipts are used based on the available date and time and there is no sorting criteria available in standard heuristics.

The BADI /SAPAPO/RRP_FIXPEG method SORT_IO_NODES and parameter CT_OUTPUT_NODES can be used to enhance the options of receipts elements to be used for fixed pegging creation. The following example code highlight the supply sorting based on date ( not based on date and time ) and supply element category
