probelm in variant:-extra character coming in Portal

Hi All,

I am EP consultant, New to BI. I am having one scenario with me.

We have one BEx iView with four mandatory variants. User trying to select value for the first three variants and checking the value, but when he is entering value for the fourth variant and checking, few characters are getting add by own i.e. u201CAMu201D character is adding in the front of entered values. For example u201CAM99u201D

But when we are trying to run from backend (BI) is not happening, no extra character is coming for the fourth variant.

In the both case we are getting out put, but when we are trying from portal why extra character is getting added.

Could you please help me on this.

Deepak!!!
