Dave,
Thanks for your response on this.
I wanted to change the usage from Military = "2" to blank which is how it was before I assigned the value.
Coming to your comment on the feeder system synching, I tried doing it from ECC but looks like the usage fields in GTS don't get updated when the same is changed and transferred from ECC.
Please let me know how you handled assigning and changing usage if you have done it in your experience?
Regards,
Prashant.
