Hi ,

Regarding the requirement wherein in the purchasing autocreate form ,i need to clear the Buyer field when clicked on Clear button.

I was recommended the following personalization.However when i add this personalization and save and close it and repoen the autocreate form, the form just hangs for a particular user.

Is there any workaround for this performance issue?

Trigger Event When new record instance
Trigger Object FIND_REQ_LINES
Condition: :FIND_REQ_LINES.SUGGESTED_BUYER is not null
