Issue

Batch is globally used in Syensqo to track and trace the movements for homogenous partial quantities of required materials/products. 

However, in Composite Materials business, there are scenarios requiring track and trace the movements for individual materials. Currently, batch is used to manage the relevant track & trace requirements. This KDD is to assess the option of using SAP serial number to handle the relevant scenarios. 

Decision

Introduce Serial Number (SN) concept and use SN to manage, track and trace the movements for the individual item rather than using batch number. 

Background & Context

In the following 2 scenarios, batch number is used to track and trace the movements for individual materials.

1). Sublot Scenario

For example, a Process Order is created in SAP to make the Master Roll, which is a piece of carbon fabric of 1 meter wide x 100 meters long. A SAP batch number, for example MROLL1, is generated and assigned to the Master Roll. Later, another Process Order is created to consume Master Roll (MROLL1) and produces 5 separate pieces. Each is 20 CM wide and 100 meters long. Then another 5 SAP batch numbers are generated to identify each of the sublots: MROLL10001, MROLL10002, ... , MROLL10005. 

2). Non-Sublot Scenario 

In another case, for example, 500 liters of a liquid adhesive (bulk finished goods) is produced with SAP batch BATCH1. It's been packed in 5 liter cans (packed finished goods). In total, there are 100 cans of  the adhesive in BATCH1. Business may number each individual cans by using unique numbers related to adhesive BATCH1, eg. BATCH1001 for can#1, BATCH1002 for can#2, etc. Those unique numbers look like sub-batch numbers, but they will only be used to physically identify the cans. They are not SAP batch numbers and are not stored in SAP currently. So those sub-batch numbers cannot be used for tracking or tracing. In other words, business can't track & trace each individual cans in SAP at the moment.

Business will print the Master and/or Sub Batch depending on the requirement. Batch numbers are limited to 10 characters. Most are 6+4 or 6+3, but other schemes are also possible.

Assumptions

1. Business needs to track & trace the relevant materials at the individual item level.
2. Master Roll and Sublot Rolls use different material numbers.
3. Bulk finished goods and related packed finished goods use different material numbers. 

Constraints

1. SAP standard serialization numbering doesn't reflect the relevant Batch numbering. 
2. Some standard Fiori Apps don't support serial number feature, for example F1061 Transfer Stock - In Plant. In this case, classic GUI transaction MIGO will be required. (Refer to SAP Notes# 3459964)

Impacts

1. Impacts on Processes

• To perform relevant material transactions, such as goods receipt and stock transfer, user need to not only specify batch number but as well as serial numbers for all the relevant individual materials.
• Since serial number doesn't directly reflect the batch numbering, user won't be able to tell the batch number by relevant serial number. (However, since batch can be configured as mandatory for the relevant serialized material, batch number will be also associated with relevant serial numbers.) 

2. Impacts on Other Domains

1). WM/EWM

When moving serialized material (meaning, material with serial number) in and out warehouse, user also needs to specify the relevant serial numbers.

2). Data and Migration

• New data object is introduced: Serial Number
• Data Uploading: Serial Numbers need to be added when uploading the relevant stocks (Stock-on-Hand) or legacy transactions from legacy SAP ECC systems.     

3. Impacts on Developments

Developments may be required to:

• Enhance the standard Fiori Apps to support the serial number features.
• Build the visual connection between the batch numbering and serial numbering.       

4. Impacts on Interfaces

If serialized materials are transacted in 3PLs (Third Party Logistics) or other TPAs (Third Party Applications), such as Neptune and Weighbridge, serial number information will need to be communicated in the relevant interfaces.  

5. Impacts on Change Management

Additional training is required for serial number management functionalities. 

Business Rules

Potential business rule if adopt Serial Number management:

- Serial number will be activated for the materials requiring track & trace at individual item level.

Options considered

Option A: Introduce Serial Number with Batch Management

Serial Number activate + SN Profile + SN in HU/SU => TB Added

With this option, during goods receipts from production, relevant SNs will be generated and assigned to each of the material. SN and relevant Batch number should be printed on the label with the scannable barcode to streamline the downstream transactions such as stock transfer, stock take, picking/packing, goods issue etc.  

1. Sublot Scenario

Serial number will be generated for each of individual Sublot Rolls with the same batch number as the Master Roll. 

In the above Master Roll example:

2. Non-Sublot Scenario 

Serial number will be generated for each of the packed FG (eg. 5L cans) with the same batch number as the bulk FG (eg. 500L adhesives).

In the above liquid adhesive example:

Option B: Replicate AS-IS Batch Logic 

With this option, a batch number will be created for the original material, eg. master roll or bulk liquid adhesive etc. Different batch numbers will be created for each of the manufactured products, eg. sublot rolls or packed liquid adhesive cans. The link between original batch and sub-batches is via batch numbering rule.

1. Sublot Scenario

For the above Master Roll example:

2. Non-Sublot Scenario 

For the above liquid adhesive example:

Evaluation

Pro's and Con's 

	Option A (SN + Batch)	Option B (Batch Only)
Standardization	Pro's: In standard SAP, serial number is used to mange stock at the individual material level. By using the SN, business can track and trace each of the material where the material is used and what's the operations been done. In the meanwhile, SN can be associated with batch number to show the relationship with the original material, either Mater Roll or Bulk Liquid Adhesive.    Con's:	Pro Pro
Traceability	Pro Con	Con
Change Management	Pro	Con
