Problem when changing object abbreviation for Program of Study

Hello,

some years ago we created a program of study (SC) with object abbreviation (field SHORT) = "PDE". Since then we've had students registered, generating a study (CS) with object abbreviation = "PDE" (CS inherits SC's abbrev).

We now detected that the abbreviation is incorrect, so we changed SC's abbreviation to "PDER", but this change doesn't impact on all CS's already created. We've been looking for a transaction to help us correct the CS's abbreviations, but had no luck.

As far as we've investigated CS's obj abbreviations appear on table hrp1000, but we's like a proper method to try correcting.

Any idea?

Cheers

Michael
