Prioritise WMS-WCS Messages
CALIDUS WMS

Functional Overview
Client Requirement
Prioritise certain messages from WMS to WCS so that they take priority over standard messages and arrive before them into the WCS. The messages to be modified initially are the UPC responses to Receipt Precheck, Putaway and Pick Replacements from Pick Shortages.
Solution Overview
The standard messaging function within CALIDUS WMS will be modified to ensure that all messages are sent at a standard message priority (i.e. 5), rather than accepting the default from the Oracle queues.
The UPC responses to Receipt Precheck, Putaway and Pick Replacements from Pick Shortages messages will be modified to be set at a high priority (i.e. 1-4). The messages affected by the high priority setting will not be modifiable by the user, so only these specific messages will be affected.
The Standard and High Priority values will be specified as system parameters.
This modification will ensure that the high-priority messages specified will be sent to the WCS before lower-priority messages.
Scope
Note: This modification affects the CALIDUS mobile system connecting to the Oracle CALIDUS WMS system only.
Note: The message priority does not affect the content of the message, just the sequence in which they are sent to CALIDUS Mobile.
Warning: This modification affects the core CALIDUS Mobile interface in CALIDUS WMS. This will require several programs to be recompiled and released, as well as a fundamental change to the Oracle Advance Queues within the database. As such, the installation of this will require scheduled downtime. No CALIDUS Mobile programs need to be released to implement this functionality, however.
Set-up
Pre-requisites
A valid CALIDUS Mobile system must be connected to your CALIDUS WMS.
Menu Structure
None
Data
Warehouse rule 'RPCA' ("RF Picking - Create Amendments") must be created and set to value 'Y'.
Functional Description
DP_WMS_IF
This Oracle package will be changed to allow the WMS RF sending packages to specify a priority on the messages sent to CALIDUS Mobile. All overloaded versions of procedure 'send_to_wcs' and 'send_edi_to_wcs' will be modified to receive a priority parameter. If no priority is specified (for the majority of messages), the priority will default to 5.
The priority of the record built to send (p_rec_dets) will be set to this parameter.
Note: The contents of this procedure contain amendments for stock take developments and changes to the way that the common record are retrieved that must be reflected in the latest version - the version differences must be checked for this. The procedures to be checked are:
- get_session_qschema_agent
- get_edi_session_qschema_agent
- recvd_rec
DP_RDT_STKENQ
Procedure 'check_upc_code' will be modified so that, when messages are returned to CALIDUS Mobile with the UPC information, they are sent with priority value '2'. This is done when the procedure 'send_edi_to_wcs' is called at the end of the procedure.
DP_RDT_PICK_CONF
This package will be modified to set the priority of any pick replacement message returned to CALIDUS Mobile to '2'.
Pick Modification messages are only returned to CALIDUS Mobile if the warehouse rule 'RPCA' is set to 'Y', through procedure 'search_for_alternative', when there has been a shortage against a particular pick line.
If an alternative pick is found, the pick task on CALIDUS WMS is created and a pick task is sent using procedure 'send_to_pick'. This procedure is called only for this reason. This procedure will be modified to set the priority of the messages to '2' when the procedure 'send_edi_to_wcs' is called from here.
If no alternative pick is found, a message is returned to CALIDUS Mobile to inform the users that no alternative pick is available. This is sent from procedure 'send_blank_pick'. This procedure is called only for this reason. This procedure will be modified to set the priority of the messages to '2' when the procedure 'send_edi_to_wcs' is called from here.
Appendix A: TEST PLAN
| Test Script / Scenario Reference | Prioritise WMS-WCS Messages | Call Number(s): 291253 PW-8KRCWE |
| Test Script / Scenario Description | Test prioritisation of messages from WMS to WCS. | PASS / ISSUES / FAIL |
| Menu Access | None | |
| Pre-requisites | See Setup section | Tested By: |
| Test Objective | To test that: all standard messages are defaulted to a default priority; high-priority messages are sent with the high priority and; messages at different priority levels are received in the sequence expected. | Date: |
| Step | Action | Result | Remarks | P/F |
| 1 | Standard Message Sending | |||
| 1.10 | Send all types of messages (for the client, this is standing data, picks). Check the sent messages on the WMS Queue and the WCS Incoming Log. | All messages enqueue with priority 5 and are received in the sequence they are sent. |
| Step | Action | Result | Remarks | P/F |
| 2 | Priority Message Sending | |||
| 2.10 | Perform a UPC enquiry (from Blind Receipt or Putaway). Check the sent messages on the WMS Queue and the WCS Incoming Log. | Responses are received and were put on the queue at priority 2. | ||
| 2.20 | Perform a short pick of stock where there is replacement stock in the warehouse. Check the sent messages on the WMS Queue and the WCS Incoming Log. | Responses are received and were put on the queue at priority 2. | ||
| 2.30 | Perform a short pick of stock where there is no replacement stock in the warehouse. Check the sent messages on the WMS Queue and the WCS Incoming Log. | Responses are received and were put on the queue at priority 2. |
| Step | Action | Result | Remarks | P/F |
| 3 | Message Queue Sequencing | |||
| Send through some standing data messages that will take time to perform (>1000 messages). All tests below should be completed before these messages have all been received. | ||||
| 3.10 | Perform a UPC enquiry (from Blind Receipt or Putaway). | A response is received in a timely fashion. | ||
| 3.20 | Perform a short pick of stock where there is replacement stock in the warehouse. | A response is received in a timely fashion. | ||
| 3.30 | Perform a short pick of stock where there is no replacement stock in the warehouse. | A response is received in a timely fashion. |
