Last updated on OCTOBER 02, 2018

Applies to:

Oracle Communications Network Charging and Control - Version: 2.4.0 and later   [Release: 2.4 and later ]
Information in this document applies to any platform.


You can identify the symptom of this particular issue from /var/adm/messages that Diameter Charging Driver (DCD) generates this following error:

ERROR: Unable to add mandatory AVP 'xxx' (tag nnn) to request (no data available for it?)

xxx represents the tag name (i.e Promotion-Call)
nnn represents the tag number

In term of call flow, you could see the call setup is failed because the billing engine rejects the reservation


The issue could be triggered by the changes on one of this following area:
  • DCD Attribute-Value Pairs (AVP) definition on eserv.config
  • or Control plan
