The Partnumber In Inventory

 

Part numbers are the primary identification link for inventory within MLS 2026.

They are used throughout the system for:

inventory tracking

workorders

purchasing

pricing

stocking

vendor management

sales history

reporting

Accurate part number management is critical to maintaining:

inventory consistency

purchasing accuracy

reliable service workflow

within MLS 2026.


Part Number Structure

MLS 2026 provides:

👉 up to 20 characters

for each part number.

Part numbers may contain:

numbers

letters

symbols

When letters are entered:

👉 the system automatically converts them to uppercase

to maintain:

consistency

sorting accuracy

easier searching

throughout the inventory system.


Recommended Part Number Strategy

It is strongly recommended that:

👉 the manufacturer’s actual part number

be used whenever possible.

Using manufacturer part numbers helps:

technicians locate correct parts

simplify purchasing

improve reorder accuracy

reduce duplicate inventory

improve vendor communication

throughout daily operations.


Manufacturer Numbers vs Scanned Numbers

⚠️ In many cases:

👉 the barcode or scanned number is NOT the actual manufacturer part number.

For this reason:

👉 MLS 2026 maintains separate fields

for:

the primary inventory part number

and

UPC / barcode information.

This allows the system to:

preserve accurate manufacturer identification

while still supporting:

scanning

UPC lookups

packaged inventory references

when appropriate.


Understanding Inventory Sorting

Part numbers are sorted using:

👉 alpha-numeric sequence.

This sometimes surprises users expecting:

👉 pure numeric sorting.

Computers sort inventory by evaluating:

letters

numbers

symbols

spaces

as:

👉 character values

rather than true mathematical values.

For example:

14577

will appear before:

185

because the system compares:

character-by-character

rather than

by total numeric value.

This is standard behavior in most computer inventory systems.


Why Consistent Numbering Matters

Consistent part numbering improves:

searching

inventory organization

reporting

purchasing accuracy

duplicate prevention

throughout MLS 2026.

Random or inconsistent numbering often causes:

duplicate inventory records

purchasing confusion

stocking errors

pricing inconsistencies


Cross Reference System

MLS 2026 includes a powerful:

👉 Cross Reference System

designed specifically for repair businesses.

In many industries:

👉 multiple manufacturers produce equivalent parts

using completely different part numbers.

The Cross Reference system allows these interchangeable parts to be:

👉 grouped together

while still maintaining:

accurate manufacturer identification

separate inventory records

proper sales history

for each actual product used.


Why Cross References Matter

A repair business may stock:

OEM parts

aftermarket parts

remanufactured parts

alternate supplier brands

that all perform the:

👉 same functional service.

Without Cross References:

operators may believe parts are unavailable

duplicate orders may occur

substitute inventory may be overlooked

MLS 2026 solves this problem automatically.


How Cross References Work

Each interchangeable part maintains:

👉 its own inventory record

with:

its own manufacturer

its own pricing

its own sales history

its own inventory quantity

However:

👉 all interchangeable items share:

a common Cross Reference code.


Example Of Cross Referencing

Assume five manufacturers produce equivalent oil filters:

127XA

FP-123

OF-1

FIL-27X

FR-02-1

Each remains:

👉 a separate inventory record.

However:

👉 all five records contain:

OF-1

in the:

👉 Cross Reference field.

This creates:

👉 one interchangeable inventory group.


Automatic Substitute Lookup

When a part is added to a workorder:

👉 MLS 2026 first checks:

available stock quantity

If the requested part is:

out of stock

or

below quantity

the system can:

👉 automatically display:

substitute inventory items

equivalent cross-referenced parts

that currently have stock available.

This greatly improves:

technician productivity

counter efficiency

inventory utilization

customer turnaround time


Important Cross Reference Rule

⚠️ Every interchangeable part must use:

👉 the SAME Cross Reference code.

This is extremely important.

Many users mistakenly place:

👉 one alternate part number

inside the Cross Reference field.

That is NOT how the system works.

The Cross Reference field is:

👉 a common grouping code

—not a pointer to another individual inventory record.

If all interchangeable parts do not share:

👉 the same Cross Reference value

the substitution system will not function properly.


Legal & Operational Importance

⚠️ MLS 2026 always maintains:

👉 the actual manufacturer part number used.

Some inventory systems suggest:

using one OEM number

then silently substituting other brands underneath it.

In many jurisdictions:

👉 this may create:

legal concerns

disclosure problems

warranty disputes

customer confusion

MLS 2026 instead preserves:

accurate manufacturer tracking

actual part identification

correct sales history

for every inventory item.

This helps maintain:

operational integrity

accurate invoicing

customer transparency

throughout the repair process.


Superseded Part Numbers

Manufacturers frequently replace older inventory numbers with:

👉 newer superseding part numbers.

MLS 2026 provides a:

👉 Superseded By

field to manage this process.


Why Superseded Numbers Should Be Preserved

Many businesses prefer to:

👉 retain older part numbers

because:

employees remember them

historical workorders reference them

customers may request them

sales history remains valuable

Deleting old part numbers often destroys:

historical reference continuity

sales analysis

purchasing history


How Superseding Works

When a manufacturer replaces a part number:

1.Create a new inventory record for the new number

2.Enter the new number into the:

👉 Superseded By

field

on the older inventory record

Then:

👉 whenever the old number is requested

MLS 2026 automatically:

redirects to

inserts

uses

the newer replacement part number.

This preserves:

old history

employee familiarity

inventory continuity

while still using:

👉 the current active part number.


Removing A Supersession

If the supersession should no longer occur:

👉 simply clear the:

Superseded By

field.

The original part number will once again function independently.


Why This System Is Powerful

The MLS 2026 Part Number system provides:

accurate manufacturer tracking

intelligent substitutions

preserved historical records

flexible inventory control

automatic replacement handling

while avoiding:

duplicate inventory

lost sales history

substitute confusion

obsolete numbering problems

This creates a highly practical inventory environment specifically designed for:

👉 real-world service operations.


Recommended Best Practices

Use manufacturer part numbers whenever possible

Maintain consistent numbering formats

Preserve historical part records

Use common Cross Reference codes for interchangeable parts

Avoid duplicate inventory records

Verify superseded numbers regularly

Preserve actual manufacturer identity on invoices

Review cross-reference groups periodically

Use UPC fields for barcode data rather than replacing manufacturer numbers

Test substitute inventory behavior regularly
