We have Project Expense setup so that the Dflt SubAcct comes from the Employee record. In some cases, there are Expense types linked to GL accts where the Emp Subacct is not a valid Acct/Sub combo (we have Acct/Sub validation enabled). In those cases, we define the correct SubAcct in a user field in the Expense Type Maintenance screen. In the SL Travel & Expense Entry screen, we have VB code to perform the correct SubAcct population if the PJEXPTYP.User1 field is populated with a value (which would override the Emp Subacct).
Deploying WebApps for the company, need to understand how to perform the same logic so that WebApps will override the Emp SubAcct if the PJEXPTYP.User1 field is populated for the Expense Type. We are not displaying the SubAcct field in WebApps Expense Entry, nor want the user to have to change it.
