PICKING WAVES

[Former Member]

HI EVERYONE,

CAN YOU TELL ME WHAT PICKING WAVE IS AND WHERE WE USE IT?

THANKS

Using wave picks, you can perform detailed planning for picking by creating work packages for picking. Wave picks consist of a group deliveries that are to be processed at roughly the same time. You can create wave picks either manually or automatically according to time criteria. Capacity restrictions can be taken into consideration when waves are formed according to time criteria. If the deliveries that are to be picked are already assigned to shipments, you can refer to these shipments when the wave picks are formed.

hi

Using wave picks, you can perform detailed planning for picking by creating work packages for picking. Wave picks consist of a group deliveries that are to be processed at roughly the same time. You can create wave picks either manually or automatically according to time criteria. Capacity restrictions can be taken into consideration when waves are formed according to time criteria. If the deliveries that are to be picked are already assigned to shipments, you can refer to these shipments when the wave picks are formed.

Integration

Wave picks are groups of deliveries that are identified by a number.

You can execute the following Subsequent Functions for Wave Picks with reference to the wave pick for all deliveries in that wave:

Planning replenishment for fixed storage bins

Creating and printing transfer orders

Confirming transfer orders

2-step picking

Creating and monitoring shipments

Printing delivery notes / freight lists

Posting goods issue

Creating and printing billing documents

You can track the processing status of the wave picks with the wave pick monitor.

Wave picks do not influence the workload that is displayed in the Rough Workload Forecast.

Prerequisites

Lean WM is the minimum implementation requirement in order to work with wave picks and most of the following functions. Of course, you can also work with wave picks if you have implemented the full WM system.

You create the wave picks using exact time parameters. For this reason, exact scheduling (down to the minute) is necessary. However, you can work with wave picks without using such precise specifications if you have implemented the route schedule and are using the goods issue time as the comparison time.

To create wave picks automatically according to time criteria, proceed as follows:

From shipping, choose Picking ® Wave Picks ® Create ® According to delivery time.

The Create/Change Wave Picks screen appears.

Enter the number of the warehouse for which you want to create wave picks.

Make the following entries in the Time frame section of the screen:

Reference date

All deliveries whose compare times correspond to this date are incorporated into wave creation for that day.

Timeslot group

You can combine various time slots by entering a timeslot group. You get a maximum of one wave pick per time slot.

Time slot

In addition to the timeslot group, specify a time slot if you only want to construct a wave pick for that particular time slot of the timeslot group.

Surplus deliveries as of

Deliveries that have not yet been assigned to a wave pick can be included when the waves are created. Enter the date as of which these deliveries should be incorporated.

Choose a processing type:

Display waves before saving (default)

Choose this processing type if you want the waves to appear onscreen, if you want to edit them before saving or if you only want to run a simulation (in the foreground).

Save waves directly

Choose this processing type if you want to save the waves immediately without displaying them first (background processing).

The system saves the waves without displaying them onscreen.

In the Filter section of the screen, there are various selection criteria that you can use to choose specific deliveries that you want to combine into wave picks.

Choose Program ® Execute.

Depending on the processing type you chose, the result is as follows:

Display waves before saving

The system displays one or more wave proposals onscreen. You can process these waves further before you save them. For more information, refer to point 8. If you just wanted to run a simulation, choose Cancel.

Information structure S159 is the basis for creation of wave picks. Updating this information structure is controlled in Customizing for wave picks (see Control update of workload data in the Implementation Guide). If you have problems creating wave picks, you should check the updating by choosing Wave Picks ® Logs ® Update.

· Save waves directly

The system displays the numbers of the wave picks that have been saved in the database.

Using the ABAP list viewer, the system displays one or more wave proposals onscreen. The following indicators appear as standard:

Green traffic light and check mark as save indicator

Waves without capacity restrictions or waves with capacity restrictions that have not been exceeded.

If you expand the wave, the corresponding deliveries will appear.

All deliveries in this wave (except for surplus deliveries) have a green traffic light. The green check mark means they are flagged to be saved.

Red traffic light with no check mark as save indicator

Waves with capacity restrictions that have been exceeded.

If you expand the wave, the corresponding deliveries will appear.

Green traffic light and check mark as save indicator

Deliveries that are not considered critical as far as capacity is concerned

Red traffic light with no check mark as save indicator

Deliveries that are in the critical range for wave capacity

Surplus deliveries are generally assigned to the first wave, which appears fully expanded on the screen. Surplus deliveries are marked with a stop sign.

In response to a capacity crisis, you could process the waves that are displayed as follows:

Exclude waves before saving

Get rid of the wave's check mark (saving indicator).

Delete deliveries from waves

Expand the wave and delete the save check marks from the chosen deliveries. The system only saves those deliveries that are marked to be saved. This means that deliveries that have no check mark will not be saved, even if they are within a wave that is marked for saving.

Move deliveries among waves

To move a delivery from a source wave to a target wave, proceed as follows:

Click on the number of the delivery in the source wave that you want to move. The delivery is highlighted in yellow.

Now click on the target wave. The delivery is moved from the source wave to the target wave, where it is marked with a plus sign.

Save the wave picks

The numbers of the wave picks that have been created appear on the screen.

The system creates a log of the activities performed. To view the log, choose Wave Picks ® Log ® Wave Pick.
