F150-custom changes

[Former Member]

Hi experts,

In the transaction F150, I need to add some code in the standard program to send mail to the customer whenever the spool request is generated for the printout.

I have a customized form assigned to the transaction F150 in the configuration settings.

I find no user-exits, so im trying to trace where in the program this form is getting called. But it seems to me that no form is getting called and i need to add my code at this point. Please help.

Form is getting called in the background and the data are fetched using the function module 'FI_PRINTING_DUNNNIG_INVOICE'. One of the solutions could be to create a copy of this FM and try to modify it.
