Warehouse Order Prioritization

Use

Warehouse order (WO) prioritization ensures that the system selects for a resource the WO that is most suitable for it.

Prerequisites

You have assigned bin access typesand handling unit type groupsto resource types in Customizing for Start of the navigation path Extended Warehouse Management Next navigation step Cross-Process Settings Resource ManagementDefine Resource Types. End of the navigation path

Activities

You maintain the following using the execution priority maintenance transaction (on the SAP Easy Access screen, choose Extended Warehouse Management Master Data Resource Management /SCWM/EXECPR - Maintain Execution Priorities ):
- Bin access type (BAT) and handling unit type group (HUTG) priorities per resource type (a value from 1-10 )
  
  The priority values reflect the preferences of a resource type to work in a particular bin access type, or with a HU type group.
- Warehouse process category (WPC) priority (a value from 1-10 )

Priority weightings per mode (a value from 1-100 ).

The weighting of a priority parameter reflects the relative importance of the parameter in determining the total priority of a warehouse task (WT). The weightings may vary according to activity, which is reflected by the mode.

Note Note

If you do not maintain a BAT or HUTG priority value for a particular resource type, the resource type is not qualified to work in the bin access type or with the HU type group.

End of the note.

When a WT is combined into a WO, it is assigned a total priority, calculated as follows:

Priority = (BAT Weighting/100 x BAT Priority Value) + (HUTG Weighting/100 x HUTG Priority Value) + (WPC Weighting/100 x WPC Priority Value)

Note
The weightings are based on the mode of the first WT in the WT sequence.

End of the note.
The total priority of the WO is set from the highest priority of its constituent WTs.

Example

Note Note

In the following example, we assume that the warehouse process category for all WTs is the same, and therefore ignore the warehouse process category priorities.

End of the note.

You maintain the following execution priorities for resource type A:

Bin Access Type Priorities

Bin Access Type	Priority
BAT1	6
BAT2	8
BAT3	4

Handling Unit Type Group Priorities

HU Type Group	Priority
HUTG1	5
HUTG2	3
HUTG3	9

You also maintain the following mode priority weightings:

Mode Priority Weightings

Mode	Priority Parameter	Weighting
1	Bin Access Type	45
1	HU Type Group	30
1	Process Type	15
2	Bin Access Type	30
2	HU Type Group	50
2	Process Type	10

Resource A is currently assigned to queue 5, to which the following WOs are assigned:

WO 4432

Warehouse Task	Mode	Bin Access Type	HU Type Group
LB 342	1	BAT3	HUTG3
LB 355	2	BAT2	HUTG1

WO 4435

Warehouse Task	Mode	Bin Access Type	HU Type Group
LB 364	2	BAT1	HUTG2
LB 340	1	BAT2	HUTG3

The priority values for resource A are calculated as follows:

WO 4432

Priority (WT 342)

= (0,45*4) + (0,3*9)

= 1,8+ 2,7

=4,5

Priority (WT 355)

= (0,3*8) + (0,5*5)

= 2,4 + 2,5

= 4,9

Total priority of WO 4432 = 4.9

WO 4435

Priority (WT 364)

= (0,3*6) + (0,5*3)

= 1,8 + 1,5

= 3,3

Priority (WT 340)

= (0,45*8) + (0,3*9)

= 3,6 + 2,7

= 6,3

Total priority of WO 4435 = 6.3
