Personalize Receivable Distribution in AR Distributions

Hi,

In AR Distributions window - we dont want users to update "RECEIVABLE" account. (This happens when transaction is created but not yet completed)

I tried couple of personalizations but it didnt work.

Any ideas on how to achieve this ?

Personalization

1. Seq -- 10

    Description - Dont update Rec account

    Condition:

    Trigger Event: WHEN-NEW-RECORD-INSTANCE

    Trigger Object: TACC_ACC_ASSGN

    Actions:

    Seq: 10

    Type: Property

    Object Type: Item

    Target Object: TACC_ACC_ASSGN.ACCOUNTING_FLEX

    Property Name: Update Allowed

    Value: False

2. Seq -- 10

    Description - Dont update Rec account

    Condition:

    Trigger Event: WHEN-NEW-ITEM-INSTANCE

    Trigger Object: TACC_ACC_ASSGN.ACCOUNTING_FLEX

    Actions:

    Seq: 10

    Type: Property
