After upgrade to PBA 5.5.5 or above the placeholder
@@Cust_Account_Type@ works differently, e.g. the condition
@@Cust_Account_Type@ == "Customer" is never satisfied.
The issue is caused by the bug with id #PBA-60224 - since PBA 5.5.
Vend_Account_Type placeholders return either
Customer as it used to be in PBA 5.4.
The bug is going to be corrected in future PBA updates, old behavior is planned to be returned to the placeholders and a new placeholder to be created for Business/Personal.
