Look-up Tables and Data Validation
The QAD CRM system also provides look-up tables to assist you in adding values in various input fields. You can access each of these tables using the corresponding Look-up button located next to the field.
The system does limited validation on the data you enter in the input fields. Wherever required, the system does not let you enter more than a specific number of characters in fields. It also checks for duplicate records.
Mandatory field names appear in red. If you leave mandatory fields empty, the system displays an error message and does not complete the task you want to perform. You can, however, leave optional fields empty.
