Resolving the INLotSerialNbrAttribute Error in Acumatica: A Practical Guide

If you're working with Acumatica and have encountered the frustrating error "INLotSerialNbrAttribute Error: must implement the PX.Objects.IN.ILSMaster interface," you’re not alone. This issue usually arises when integrating a custom screen that uses the INLotSerialNbrAttribute for handling lot serial numbers. But fear not! In this guide, we will walk you through the steps you can take to solve this problem effectively.

Understanding the Problem

You're likely trying to use the INLotSerialNbrAttribute in a screen that should allow for the entry of a single Serial Number per line, reminiscent of how the adjustment screen operates. The error message suggests that your Data Access Class (DAC) type does not implement the required ILSMaster interface. This interface is essential for enabling proper interactions between your DAC and the serial number functionality within Acumatica.

What Causes the Error?

The issue surfaces due to the absence of the ILSMaster interface in your DAC. The INLotSerialNbrAttribute requires this implementation to manage inventory items and their serial numbers accurately. When this requirement isn't met, Acumatica will throw the aforementioned error.

Steps to Implement the Requested Interface

To resolve this issue, follow these organized steps:

Step 1: Implement the ILSMaster Interface

To start, ensure that your DAC class implements the ILSMaster interface. Here’s a basic example of how to define your DAC:

By including the ILSMaster interface, you indicate that your class will handle lot serialization logic.

Step 2: Define Required Fields

Within your DAC, make sure to include all necessary fields that the ILSMaster interface requires. If specific fields are not critically needed, you can declare them as non-database fields (e.g., PXInt instead of PXDBInt) and use unbound defaults to provide any requisite information.

Step 3: Set Defaults for Inventory Multiplier

As an example, the InvtMult field is pivotal for determining the type of transaction, whether it is a receipt or an issue. You can set this value to default to -1, 0, or 1 based on your application's needs. Here’s how you might implement this:

Step 4: Verify Grid Columns and Selectors

Ensure your grid configuration aligns with the expected attributes. Each visible field in your grid's template should correctly reference the properties defined in your DAC.

Example of Updated Grid Template

Here's an example configuration of your grid to ensure it properly integrates with the new configuration:

Conclusion

By ensuring your DAC implements the ILSMaster interface and aligning your grid's configuration with the required attributes, you can successfully resolve the INLotSerialNbrAttribute error in Acumatica. This allows for streamlined handling of lot serial numbers and enhances the overall functionality of your custom screens.
