Project Expense Report Account Generator(PAAPWEBX)

Project Expense Report Account Generator(PAAPWEBX):

This workflow generates the account during the iExpenses process.This called from the workflow 'Expenses' (APEXP).
The process calling the account generator is
'AP Validate Expense Report' -> which calls the API AP_WEB_EXPENSE_WF.APVALIDATEEXPENSEREPORT
which internally calls various API's before calling tge account generator from pa_acc_gen_wf_pkg.ap_inv_generate_account
which calls the standard FND API's for generating the code combination for the generator.
fnd_flex_workflow.generate( l_itemtype,l_itemkey, etc
l_error_message which passes back the workflow error.

So the API calling is as follows

iExpenses
Calls AP_WEB_EXPENSE_WF.APVALIDATEEXPENSEREPORT
Calls pa_acc_gen_wf_pkg.ap_inv_generate_account
Calls fnd_flex_workflow.generate

To debug the account generator use the following profile.
Account Generator:Run in Debug Mode preferably at the user level which shows the account generator workflow in workflow admin.
