Setting Up Quantity Type Subsets

You should not change the 34/QT UDC table; however, you can create a subset or a custom quantity type UDC table. Because companies like to make decisions about what quantity types appear on the time series, creating a custom quantity type UDC table gives them flexibility. For example, a distribution warehouse does not want to see the quantity types for work orders.

The software provides multiple subsets of the UDC 34/QT, for example, 34/DR for Distribution Requirement Plan (DRP) and 34/MS for Master Production Schedule (MPS).

For the system to access UDC 34/QT during DRP, MPS, or Material Requirements Planning (MRP) generation, you must set the UDC Type field on the Parameters tab in the processing options for the MRP/MPS Requirements Planning and Master Planning Schedule - Multiple Plant programs. Setting this processing option with a value of QT enables the planning system to use all of the available data and create a time series for every transaction that it is capable of making.

You can use the custom UDC 34/DR or 34/MS quantity types by setting the Alternate UDC Type (Optional) field on the Defaults tab in the processing options for the MPS Time Series program (P3413). You can then use the Alternate Quantity Type option on the Work With Time Series form to determine which UDC quantity types you view in the time series.
