Efficient  resolution of EPCIS data exceptions will be key to ensuring pharmaceutical products move  through supply chains and reach patients in a timely manner. 
When  physical products arrive at a distributor and the accompanying data doesn’t match,  how will the industry resolve those issues? At HDA’s 2021 Traceability Online Seminar, experts held a roundtable discussion for trading  partners—manufacturers, suppliers, and distributors—to discuss exception  management concerns. HDA’s  workgroup around exception handling has identified approximately 19 different  scenarios deemed exceptions.
Libby  Dewey, sr. consultant, operations technology at Cardinal Health, Inc., and Mike  Mazur, director, trade operations at Pfizer Inc., co-facilitated the  discussion. Pfizer has “been live” with Cardinal on EPCIS data exchange for the  past eight months (along with other trading partners) which has yielded preliminary  feedback and learnings on how to deal with exceptions in the data exchange  files they’re sending.

Product  without data
Of the many  different scenarios deemed exceptions, one major example is overages. In this “product/no  data” case, the downstream trading partner may have 16 cases show up, but only receives  data for 15 of those. How does the manufacturer get notified of the issue so  they can begin their investigation? How does the manufacturer correct that transaction  information so that case can be removed from quarantine in a timely fashion? (It  should be noted that “timely” is a relative term at this point.)
The workgroup  is looking at developing standards for how a distributor would notify a  manufacturer and what information and formatting that notification would entail,  such as the product identifier and the delivery/PO the extra case was on.  “That’s really where the industry needs to be in the next two years, to put  processes in place to be able to handle if we do have an instance of product/no  data,” said Mazur. “There is ongoing work within HDA in these workgroup  sessions to help standardize the messaging between the distributor and the  manufacturer.”
It may not be  so simple to identify which case is the extra. From the distributor perspective,  Dewey noted, “We’re working on the way that we're going to pick out the excess  product, how we're going to identify it, and how we're going to communicate  that. We see this currently as an extension of how we're handling returns  verification exceptions—which we're doing right now—as well as an extension of  how we're handling ASN [advance ship notice] overages and things of that  nature. We're planning to sample on inbound and utilize a type of interim status  to identify a product that has been received inbound, but not picked yet for  outbound and verified.”
Of course, manufacturers will then  need to investigate the issue on their end to determine the cause. “We need to  understand why we don't have a ship event against that product if it was  shipped. Was something sent that shouldn't have been sent? Or what’s missing to  close that loop? Is there an overage and an under-data scenario that we need to  research?” said one attendee who is part of the workgroup said. “And with data integrity  issues, it’s not as easy to generate something that's missing. We've taken that  back to our internal team to walk through all the steps that are needed, but  it's just that added complexity that's not as easy to fix, while we also try to  build in proactive measures as much as we can to not run into that.” 
Other exceptions 
                                                                
Manufacturers  have to start looking at exception scenarios and how they’ll resolve each.  Issues may be site-specific or broader, in nature. A few other examples came up  in discussion including:
- Flags, such as whether a batch is serialized and  aggregated to a case or pallet, drive other processes in the system. If an  aggregation flag is not set, the system is not going to look for the parent-child  relationship and infer the contents. The manufacturer then ships out good  product, but only with a case-level serial number and not the contents of that  case, because the flag was not checked properly.
 - Data issues include GCPs  incorrectly formatted causing the whole file to fail, the syntax GLN is  incorrect, or GTINs are missing.
 - If a case is the unit of sale, but the contents of the  case are also serialized, the differing case GTIN and content GTIN can cause  the file to fail.
 - An exception  discovered later can also add to the complexity, as not all issues will be discovered  in receiving. A product/no data situation may not be found until the product is  actually picked (deeper into the process), and which point it would go to  quarantine. “A worst-case scenario is ultimately product that's found in a  fulfillment area of a distributor where it's been disassociated from that  shipper case… you don’t know what delivery that came in on or its shipper-case,”  said Mazur. 
 
Throughout  the seminar, attendees made mention of seeking clarity around processes for decommissioned  product.
Data/no product
The  opposite problem of product/no data can occur where a distributor receives more  data and less product, if perhaps product is shipped to an incorrect customer  while data is sent to the correct customer. In this case, distributors may not  have a process developed to do anything with extra data. It’s likely the  manufacturer would discover such an issue first as distributors routinely  receive data followed by the physical shipment a day or two later. This makes  it difficult for the distributor to determine what is extra data vs. what  product simply hasn’t been received yet. “We don't know that the product is not  still on its way to us. We're certainly open to coming up with a process to  give feedback should the industry decide that there's some mechanism that makes  sense for that,” said Dewey.
 
Staffing
An  attendee asked if a certain department handles the back-and-forth at the  manufacturer site. In Pfizer’s case, they have a dedicated group handling  overages and missing files with regard to lot traceability, but for the EPCIS  data exchange, which is not yet a regulatory transaction, they are still  onboarding and in test mode. “We're still learning, we're still identifying  what tools we’ll need to build in order to fix discrepancies. Some discrepancies  will be fixed at the site, some of them can be fixed in the market. Some of  them have to be fixed by a quality individual,” said Mazur. “Ultimately we’ll build  the processes to fix them. Right now, we have the luxury of learning.”
Organization  and product location
Items with data issues will be moved  into a quarantine section, to be held until the exception is resolved. “A big challenge  that we’ve found is just making sure that we have a good organization system to  be able to facilitate finding that product—especially if we have high volume—when  we get the information back from the manufacturer,” Dewey said. 
 In a related roundtable, speakers discussed what systems distributors  may use to locate product once an exception is resolved with the manufacturer. Ian Cannell warned attendees of potential space constraints,  particularly for worst-case scenarios where an entire pallet or more must be quarantined. 
   Matt Sample is VP, manufacturer  operations at AmerisourceBergen Corporation. As he explained, “We’re leveraging  software called Investigator from LSPedia  for exceptions today. We were using them for saleable returns, and we’ll most  likely be using that going forward for exceptions so that we can log them…. All  exceptions would be managed centrally. I have 26 DCs [distribution centers], so  when we clear an exception, we will communicate to the DC that it's okay to  release said quarantined inventory.”
Sample reiterated Dewey’s point that volume  matters. One box can be moved back to distribution quickly, but for a high volume of product, it may be challenging to find or create bin locations for every  exception. Without data to determine how many exceptions there will be, methods  of organizing remain “to be determined.”
  Could RFID or IoT stickers play a role in locating  product in quarantine? It is certainly a possibility. However, distributors  commented that solutions would need to be implemented at the manufacturer level,  and it would require many manufacturers adopting the technology on case packs in  order for it to make sense. (For clarity, this would not replace 2D barcodes.) Distributors would also need to factor in time spent scanning if any IoT (internet of things) solutions are added.
Co-facilitator Omid Ghobadi, sr. director, finance  & technology at HyGen Pharmaceuticals, Inc. noted that Walmart may have had  a similar experience with their serialization in the past. He added, “That  could work to scan a high volume of product as soon as the pallet hits the  dock, but like Matt mentioned, it should come from the manufacturers. And, you  cannot have that only for two manufacturers—it only works if the majority sign  up for this technology.” 
Closing  thoughts
The conversation at the seminar touched on the  more philosophical and ethical issues around serialization requirements and  drugs critical to patient care. In 2023, companies will be faced with handling  exceptions and fixing data issues while some patients wait for life-saving  treatments. And further to that point, can a company be sure it’s merely a data  issue?
This should be a strategic conversation  between compliance and legal groups at an organization. If product can’t be  received per the intent of the law, will trading partners have the SOPs and bandwidth in the  schedule to quarantine it and follow exception management procedures?
As is  the case with any DSCSA-related news, experts advise to start working as soon  as possible to put processes in place for exceptions, to minimize issues that  could hold up patient care.
