read payment method from FPY1 in event 1795

hi experts,

I need to know the payment method entered in FPY1 in event 1795.

In event 1795, this value is know imported.

So read that i it's possible to do it via Via MEMORY ID 'FKKMADADDONS’ using structure FKK_MAD_PAYP during mass activity.

But really, i see not how to do it.

Any idea would be helpful

regards,

Tierno
