hiding fields Infotype screen control

Hi experts,

i have to hide few fields in Pension fund (71) infotype.I couold do that using view v_t588m.By doing so my fields are getting disabled even in the other subtypes too.

In one of the forum discussions experts have asked to do it through feature.

I have gone through the previous Forum discussion relevant to this.But i am not able to replicate to my scenario.

Please expalin how the fields can be hidden in one subtype and the same should be visible in other subtype.

Please reply immediately.
