How to get output channel of a billing output form in S4HANA?

[himanshukawatra]

Hello,

Developed a custom driver program that calls a custom Adobe form, to generate the billing output form.
All the configurations are done in BRF+ and OPD and everything runs smoothly until there pop up the request to attach this document with the billing document.

In my driver program after I call the functions
FP_JOB_OPEN.
The function that generates the form
FP_JOB_CLOSE

I have implemented a perform called ATTACH_PDF.

but when in the BRF+ the billing output gets mapped for 2 channels
PRINT
EMAIL
the attach perform gets called twice since the driver program runs twice, once for each channel.

Is there any class/method/ FM that I can call so that I can get as a response the channel of this output, so I can put the ATTACH_PDF perform inside an IF statement and execute it only on the print channel???

Thanks in advance.
