Autocomplete rule : How to configure rule with multiple conditions ?

Summary:

We want to configure the following rule :

IF worker category = 'Exécution' THEN

****_Attribute1 between 'GF 3' and 'GF 6'

=> error message displayed if condition not respected

Content (required):

What we noticed is the following:

-for numeric DFF (attribute number x), it works (cf. attached document => slide 1)

-for alphanumeric DFF, it works only with one condition. If multiple conditions are set within the condition group, we don't have the expected behavior (cf. attached document => slide 2)

As per methodology, I proceed by iteration, meaning:

-I split rule into different pieces = OK

-I test & validate one condition = OK

-then I add another condition to test the consolidated rule = KO
