With the pandemic still raging across the globe, the question many organizations are asking is, are supply chain teams prepared to continue working off-site? The answer is, that depends on what software and processes they decide to use.

For months, teams adapted as best they could to what they initially hoped was a temporary situation. The strategic approach was to defer large investments in new solutions while the depth and breadth of pandemic-related issues were sorted out.

After about a year of trial and error, organizations have a better handle on which things worked and which did not to maintain smooth-running supply chains. As we head into 2021, here are a few recommendations based on those experiences.

Oracle WMS does not yet offer the ability to perform transactions in a disconnected mode. While there are many reasons that a client might need such a capability, in this post I am focusing on the ability to do cycle counts in an offline or disconnected mode. While there are a ton of use cases for such an application, pretty much wherever there is a need to store and track inventory remotely, I am going to focus on two here, for the sake of brevity:

1) off-site storage, and;
2) the life sciences and health care industry.

Off-site Storage

One of the problems that today’s warehouses have to deal with is the issue of off-site storage. There are many reasons that warehouses have to utilize external storage facilities. While not optimal for the normal course of operations in the supply chain, they do offer a less expensive and temporary alternative that allows a business to deal with temporary spikes in demand. All too often this so called “temporary” storage solution has a way of morphing into a semi-permanent adjunct to the main warehouse. No matter the reason, the fact remains that many businesses do have to deal with this reality.

There are a host of challenges that this situation presents, including the need to manage FIFO effectively, minimizing travel and transportation costs, planning replenishment, and accounting for this inventory in your scheduling and lead-time calculation processes. One of the primary challenges we are seeking to address is the ability to maintain accurate inventory by having the ability to perform cycle counts. Most often these off-site storage facilities are managed by a third-party provider who has their own logistics system. Other times there is no wireless coverage available.

Life Sciences and Healthcare

The second use-case we have seen is in the life-sciences and healthcare industry where medical device manufacturers maintain consigned inventory with various hospitals and with their own sales people. Again, it is not possible to log on to your own network and effectively perform transactions.

We have tried in the past to do this through cell-phone networks. Although the technology exists, it has been our experience that the speeds and capabilities needed to perform such transactions are not yet where they need to be.Therefore, at Gaea, we decided to create an offline counting application that allows customers to schedule counts through Oracle WMS as they normally would, download them to their device of choice, and then be able to perform cycle counts at remote locations. Once they are no longer in their proprietary network, the app detects that it is no longer able to establish a connection with the host ERP and transitions to an offline mode. It then allows them to perform the cycle count of their choice (note that multiple cycle counts could be downloaded).

The app then simply syncs back up once they are back in the home network. Alternatively, the counts can be emailed for uploading into the host system.

We built this to run on pretty much any device that supports a browser, including iPhones, iPads, Android-based tablets and smartphones, and on Windows-based rugged devices. The goal was to build an app that allows you to do what you need to get done in the simplest and most unobtrusive way possible while addressing an obvious pain point for a lot of clients.

Q: What customizations can be made to Oralce WMS MSCA mobile picking? Any examples?

A: Almost all WMS/MSCA pages can be customized to add additional fields, perform different validation logic when leaving certain fields, execute certain business logic, etc. The pick page can also be customized, but with more possibilities and complexities.

Sample pick customizations include capturing additional dimensional fields (e.g. length and width of an item) after a user scans an item, and later on populating those values in the delivery detail, and performing miscellaneous receipt or cycle counting on the fly when there is not enough on hand during a pick.

Q: How can we customize the pick page?

A: There are two techniques to customize the pick page. The first one is to follow the Oracle MWA implementation guide: extend the MWA function class, page classes, and modify the seeded form function to call these new classes.

The second one is a less-known but preferred technique. By inserting a configuration record into one of the MWA configuration tables, the extended page classes can be loaded on the fly. In other words, if you want to add a field to the main pick page, you only need to extend one Java file.

Why it is desirable to use the second technique and to enter uncharted territory will become clear in the following question and answer.

Q: Why is pick customization so important?

A: Three factors made the pick page much more complicated than most WMS/MSCA pages. Firstly, there are half a dozen flavors of picking all performed by the same page. Secondly, all flavors of pick starts with the employee sign-on page to capture data such as equipment and zone, which requires customizing a pick page with the traditional MWA technique to modify at least four more files. Thirdly, the pick page is built on “configurable page” technology, which adds another level of code to understand.

Q: Do we need to look at Oracle Java source code to do the customization? How?

A: Yes, you must read Oracle Java source code in order to proceed with your customization. According to your Oracle apps license, you must contact Oracle to obtain the source code. It usually takes weeks for the request to go through, and you have to tell Oracle not only which file, but also which version of the file (like 11.5.10.123) you will need.

If you are pressed for time, there are general decompiling tools for obtaining Java source files from class files, such as jad. And most of the files related to picking are under $JAVA_TOP/oracle/apps/wms/td/server.

Q: How about PL/SQL source code? Where are those files?

A: In most cases, you will also need to read PL/SQL code (and write your own pl/sql logic). Fortunately, PL/SQL source code is shipped with the Oracle installation, and those files can be found under $WMS_TOP/patch/115/sql and $INV_TOP/patch/115/sql.

Q: Can we modify the Oracle source files to add new fields?

A: No. In most cases, you should not modify Oracle source files, unless you are certain what you are doing is actually fixing bugs that may exist in the Oracle code, which we have occasionally encountered in the past.

Note that future Oracle patches or releases will wipe out your changes, unless you convince Oracle to include your changes (if they are bug fixes that will be generally useful to all customers) in their future code.

Q: We pick lot numbers. Is it possible to customize the page where lot numbers are entered? How?

A: Yes. Use the second customization technique mentioned above. Otherwise, you will have to extend six files to reach this page.

Q: What skills are required to customize the pick page? How do we evaluate whether we or an outside consultant is capable of customizing our pick page?

A: The following skills are mandatory: Java, PL/SQL, Oracle JDBC, MWA developer framework. Knowledge of code under $JAVA_TOP/oracle/apps/wms/td/server, or willingness to read this code, is highly desirable. To evaluate candidates for customizing pick pages, use this FAQ as a checklist.

Q: How long should we plan for developing and implementing pick customization?
A: A typical pick customization (e.g. adding an additional field on the main pick page to capture data), will take four to six weeks for an experienced consultant to complete.

Q: Can the same technique for customizing a pick page be used for other mobile pages?

A: Yes, it certainly can, and is usually easier.
