Problem with creating a new row in SNMP table

[Rachwal Waldemar-AWR001]

Okay, found it. The row was incomplete and agent couldn't fill up it as
missing variables were devoided of DEFVAL in the MIB, so the problem.

Subject: Problem with creating a new row in SNMP table

I have stuck at the attempt of creating a new row in my SNMP table.
I'm giving 'inconsistentValue' on column (in the MIB : btsRowStatus = {
btsEntry 114 }) which is of the RowStatus type.

This is the first message I send to the agent, so the table should be
empty.
The value of btsRowStatus in SET-REQUEST is 4 which is createAndGo.
The first and the last two varbinds in the PDU are simple variables (not
table columns),
but it should not matter, I assume (these vars are additional
correlation tags and journal number required by the application).

ACCESS rights of all of the columns, including btsRowStatus, are "cr-"
create-read, so they should be okay?

The agent chokes while applying table_func with 'is_set_ok':

   apply: snmp_generic,table_func,[is_set_ok,
                                   [466944,0,1],
                                   [{1,0},
                                    {2,0},
                                    {3,"4000M"},
                                    ...
                                    {114,4},  <--- btsRowStatus,
createAndGo(4), 3rd varbind
                                    {118,0},
                                    {123,0}],
                                   {btsTable,volatile}]


... and the log after "apply:"

The full logs, from agent/erlang and manager/perl are attached to this
mail.
If MIBs are required to look at I can send them after some slimming as
they are proprietary stuff :(

Could anybody help? I have no idea what to do next :(

BTW, I'm also curious what is the best way to tackle such sort of
problems...
(a big land of unknown code but you're determined to utilize it)
Debugging, tracing? I read about, but have never used.

Thanks,
WR.
