Process Pick Requests Program

You run the Location Selection Driver program to process all movement requests at a particular status and create location suggestions. The same program processes putaway, picking, and replenishment requests. If you create a version of the Location Selection Driver, you can define the type of request to process on Data Selection in the program's processing options.

Use the versions list to review the predefined versions of the Location Selection Driver program, such as Process Pick Requests and Resuggest Pick Requests.

When you run the Process Pick Requests version, the program performs these functions:

Function	Purpose
Locates outstanding pick requests	The system searches for outstanding requests (requests for which you have not yet created suggestions) in the Warehouse Requests table. The system selects the requests that have a warehouse code of 2 (picking). The Data Selection function of the program controls this process.
Creates error messages	The system creates an error message, which it displays during pick confirmation, in these instances: Errors on the audit report. The pick request's status is not 200 (Request Created) or 220 (Suggestion Created). Pick suggestions exist, and you have not set the program's processing options to create alternate suggestions. You tried to create alternate pick suggestions after you confirmed the original suggestions. The warehouse (branch/plant) is not a valid warehouse in the branch/plant constants. The system cannot convert the transaction's unit of measure into the item's primary unit of measure. The item's primary branch/plant record does not exist. The item's warehouse process groups and order group do not reference a valid picking instruction table.
Selects an instruction table	During process selection, the system selects a picking instruction table for an item by comparing the item's warehouse process groups and order group to the groups specified in the process selection table. The system uses these priorities: Match all three warehouse process groups and the order group. Match all three warehouse process groups. Match the order group. After the system locates the most accurate match, it uses the picking instruction table that you specified for that combination of groups. The picking instruction table must include a unit of measure that also exists in the item's unit of measure structure, or the system cannot create picking suggestions.
Selects location types	After the system selects a picking instruction table, the method code attached to the table determines which location type that the system suggests: Fixed locations Random locations If you specified a zone in the picking instructions, the system searches for locations only within that pick zone.
Selects locations using location requirements	From the remaining eligible locations, the system selects the locations that: You can use for picking. Are not the location to which you are moving the item (usually the shipping dock).
Selects locations using pick instructions	The system ranks the eligible locations according to the tiebreaker that you specified in the picking instruction table. If you use this criteria, the system selects the locations for which you can: Meet or exceed the minimum pick percentage for the location. Avoid exceeding the maximum pick quantity for the location. Combine smaller units of measure into larger units of measure, if necessary roll up. Require automatic replenishment after you deplete the items in the location (for fixed picking locations only). Use the First In First Out (FIFO) picking method based on the commitment method you specify on Branch/Plant Constants. You can set the picking method to: Avoid using FIFO. Instead, rank locations according to the tiebreaker. Rank locations from the lowest lot number to the highest lot number. Rank locations from the earliest expiration date to the latest expiration date for the date that you stored the item. Rank locations from the oldest date to the newest date that you received the item.
Selects locations using the location profile	If you use this criteria, the system selects locations based on whether the location profile detail enables you to: Use the location for picking. Include the location in the pick zone, if you specified one in the movement instructions. Use the location's picking sequence number as a tiebreaker to rank locations that are otherwise equally suitable. Use the location's proximity (latitude, longitude, and height) to the shipping location as a tiebreaker to rank locations that are otherwise equally suitable.
Picks from locations according to item availability	From the eligible locations, the system picks items according to this priority: Pick from locations with available quantity, ignoring inbound quantities (incoming purchase orders). Pick from locations using any available inbound quantities. Pick from locations that you replenished because of automatic replenishment. The system displays an error message if it cannot satisfy the pick request using available, incoming, or replenished quantities. If the customer does not allow the partial shipment of an order, the system automatically deletes any pick suggestions for the order, and you do not fill the order.
