# Set Form Level Validations in Setup Items YouTube: [How to Assign Form Level Validations in Setup Items to Users in Logic ERP Software?](https://www.youtube.com/watch?v=mBts9xlzcT0\&t=245s) In this tutorial, we'll explore how to use expression validation item configuration-wise in Logic ERP. This feature helps maintain data accuracy by applying custom validation rules during item creation. *** ### Steps to Apply Expression Validation in Logic ERP * Navigate to **Setup Items** and then click on **Setup Items Multiple Pack Sizes**. * By default, groups are marked as **Not Required**, allowing item creation without entering group details. * To apply validation, mark the **Gender Group** as **Required**.

The image shown above shows that the Gender group has been marked as required by right clicking on it.

* Add an **Expression** in MRP ensuring it is greater than the sale rate.

The image illustrates how expression is defined.

* As soon as you apply an expression in MRP, it will be displayed in red color.

The above shown image shows that MRP field is marked in RED color stating that the expression has been applied

### **Testing Validation Rules** * Start creating an item. * Skip the **Category Group** to test validation. * The system will prompt an error message: *"Group 1 cannot be blank"*.

The image shown above displays the error message shown due to the validation applied on the group when left blank.

* Enter a valid category and proceed. * Set **MRP less than Sale Rate** to check expression validation. * The system will display: *"MRP must be greater than the sale rate"*.
* Enter a correct MRP and successfully save the item. ### **Creation of Item Setup Configuration** * Navigate to the Setup and expand Setup Items. * Locate the option "**Setup Configurations for Item Setup**". * Enter a configuration name and save the data.
* Now, click on "Set Configuration" to create a separate configuration for individual users.
### **Assigning User Access Rights** * Navigate to **User Access Rights**. * Select the user and assign "Setup Item Configuration". * Assign configurations: * **Aakash** → Finished Item Configuration * **Rahul** → Raw Item Configuration
### **Supervisor Role: Setting Validation Rules** * Log in as **Supervisor**. * Navigate to **Setup Items Multiple Pack Sizes**. * Set validation rules: * **Raw Item Configuration** → Mark **Category** as mandatory, enforce **MRP > Sale Rate**. * **Finished Item Configuration** → Mark **Fabric** as mandatory. ### **Testing User-Specific Validations** * Log in as **Amit** (Finished Item Configuration user) and check the fabric field validation. * Log in as **Rahul** (Raw Item Configuration user) and check category and MRP validation. **Conclusion** Expression validation in Logic ERP ensures data consistency, accuracy, and compliance across inventory management. Supervisors can define and enforce validation rules, minimizing errors and improving efficiency. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
