Read the values of an internal table without loop

Hii together,

I will read an internal table from type bapiret. I will check, if my internal table has error values or info values without to define explicit a structur from type bapiret and check my table step by step with a loop statement.

I don't know if there is a possibility to check an internal table.

Has somebody some advices or experience how to check the values of an internal table without loop?

Thanks and regards,

John
