Optimal number of control and info parameters on event handler

Hello Guru’s

We have integrated TM and EM for FO tracking, in few scenarios FO can have more than 200+ FU’s assigned to it.

We are using “ODT20_ASSIGNED_FU” control parameter to hold assigned FU’s information on EH, is it good to have more than 250+ control parameters on a EH? Is there any suggestion on optimal number of control and info parameters on event hanlder.

We also have FU’s as tracking ID’s on FO.

Thanks in Advance,

Vishwa.
