Start Tax Return Process' Field conditions

[mohseen38]

Could you please help me what methods i can use to implement in both form and list views.
@Chuck Tomasi @All Developers
Given I am a Mobility fulfiller/mobility lead/mobility admin,

When I try to check the field 'Start Tax Return Process (Destination)' /'Start Tax Return Process (Home)' from Tax Info form/list view,
Then it should only get checked if the pre-set conditions satisfy

1) Conditions - 

A) For checking Field - 'Start Tax Return Process (Destination)' -
i) Tax Return Required (Destination) is NOT Empty

ii) Tax Vendor (Destination) is NOT Empty

iii) E-List included (Destination) is NOT Empty

iv) E-List Reason of Inclusion (Destination) is NOT Empty

->Once the field is checked & updated/saved the form/list - the field 'E-List Sent to vendor (Destination)' should be auto populated with current date and made 'Read -Only'

B) For checking Field - 'Start Tax Return Process (Home)' -
i) Tax Return Required (Home) is NOT Empty

ii) Tax Vendor (Home) is NOT Empty

iii) E-List included (Home) is NOT Empty

iv) E-List Reason of Inclusion (Home) is NOT Empty

-> Once the field is checked & updated/saved the form/list- the field 'E-List Sent to vendor (Home)' should be auto populated with current date and made 'Read -Only'


2) Error message - (Both Form/List view)
A) For Field - 'Start Tax Return Process (Destination)' -

In case the conditions do not match and user is trying to check the checkbox of field from form view/list view, user should get an error prompt and any update to the field should not be saved.

Message - 'Below field(s) are required to be completed before checking this field. Please fill and try again.
Fields - <Add custom field name> <only the fields out of below 4 that are empty to be mentioned in the error'>
1. Tax Return Required (Destination)

2. Tax Vendor (Destination)

3. E-List included (Destination)

4. E-List Reason of Inclusion (Destination)

B) For Field - 'Start Tax Return Process (Home)' -

In case the conditions do not match and user is trying to check the checkbox of field from form view/list view, user should get an error prompt and any update to the field should not be saved.

Message - 'Below field(s) are required to be completed before checking this field. Please fill and try again.
Fields - <Add custom field name> <only the fields out of below 4 that are empty to be mentioned in the error'>
1. Tax Return Required (Home)

2. Tax Vendor (Home)

3. E-List included (Home)

4. E-List Reason of Inclusion (Home) '

3) Note - In case of List view multiple records update, if condition matches for 4 out of 5 records, 4 record fields should be checked and error should come for the 5th record only.
