Modify datum

[salil]

Hello ,



I'm trying to modidy a datum from a model to the datum for the geometric(the datum I'm trying to add now was already added by me few days back then I made some changes In the cast model & regenerated the machining model & the datum is missing while in geom tol frame it is showing an another datum with it's default name) tolerance while doing this Pro/e is prompting me as datum already exists & this is a merged machining model of a cast model.



I've gone thru all the possible feature& feature name finding procedures but coulden't locate this datum.......



Can anybody help me to resolve this issue ?



Thanks In Advance.
