Narrative:
Air carrier #1 was level at 11000 ft. Air carrier #2 was climbing to 10000 ft. I issued air carrier #1 traffic. Air carrier #2 climbed on an RA. Air carrier #2 climbed on an RA, also. Supplemental information from acn 629738: air carrier #2, a crj was under my control climbing to 10000 ft. Air carrier #2 was given traffic at 11000 ft. Air carrier #2 advised he was climbing for an RA. I instructed air carrier #2 to descend back to 10000 ft as the traffic was at 11000 ft.
Original NASA ASRS Text
Title: A D10 CTLR WORKING DEP RADAR WAS ADVISED BY A CLBING CRJ OF TCASII RA AND CLBED THROUGH 10000 FT THAT CAUSED AN MD90 IN CRUISE AT 11000 FT TO RECEIVE A TCASII RA AND ALSO CLB.
Narrative: ACR #1 WAS LEVEL AT 11000 FT. ACR #2 WAS CLBING TO 10000 FT. I ISSUED ACR #1 TFC. ACR #2 CLBED ON AN RA. ACR #2 CLBED ON AN RA, ALSO. SUPPLEMENTAL INFO FROM ACN 629738: ACR #2, A CRJ WAS UNDER MY CTL CLBING TO 10000 FT. ACR #2 WAS GIVEN TFC AT 11000 FT. ACR #2 ADVISED HE WAS CLBING FOR AN RA. I INSTRUCTED ACR #2 TO DSND BACK TO 10000 FT AS THE TFC WAS AT 11000 FT.
