Deletion of incorrect delta request

Hi All ,

Scenerio:- A delta load turned red , when activated on 17th(their were few incorrect characters , which could hav been the corrected & saved at PSA level & updated) this is what we do normally.

17 being holiday , we missed on it , so delta loads for following days are also their.But it doesnt get activated

Now I dont see 17th PSA data , jst cn see PSA data for 21 & 22.(these 2 data packs also has invalid characters)

Following approach tried

A)I deleted the 17th red request & tried activating 21 & 22 request.it doesnt work

my question is wat if I delete all request for date 17,21,22 and do delta run frm same pack.In this case will it pick all changed

records since last data extractn on 16th.

please suugest.
