Data quality rules

Business rule	Description	Status	Criticality
Identifier format inaccurate (GUI registration number)	GUI registration number consists of two l3etters followed by 8 digits. This rule checks possible whitespaces, hyphens where they are not specified in a reference format or dots that might be comprised in the identifier value. If there are any whitespaces, dots or hyphens then the rule is violated. This rule checks the syntax, i.e. format of the GUI registration number with respect to the format. Any deviation (i.e. white spaces where they are not specified) result in a violation.	IDEA	INFO
Identifier format invalid (GUI registration number)	GUI registration number serves as the official accounting document for tax reporting purposes. This rule allows for two different formats. First, the presence of exactly 2 letters followed by exactly 8 digits without considering possible whitespaces, hyphens or dots that might be comprised in the identifier value. If there are less/more digits, unexpected non-digits characters then the rule is violated. And second, the presence of alternatively just exactly 8 numeric digits.	RELEASED	ERROR
