SRM &_EVT_OBJECT.MATERIALGROUPLIST& question

[Gordan Flego]

Hello all,

in SRM Shopping Cart workflows:

I would like to include this expression in starting conditions for
shopping cart but do not know from where this expression is filled.

Do you have any example?

My intention is to exclude some material groups from approval process.
So expression 2 must somehow contain list of excluded material groups.

TIA

Gordan
