 Description   

Creation of an item prototype of type dependant item is not possible because LLD macros are not accepted in item Key.

Example:

Cannot update item prototype
Invalid key "K_ACK_report_2_{#PELENV}_

{#MATCH}_2" for item prototype "Kondor_ACK_report_{#PELENV}

_
{#MATCH}

2" on "TMPL_ITCBSOPS_KONDOR": incorrect syntax near "{#PELENV}

{#MATCH}

_2".

I forgot to mention: if I remove the LLD Macros from the Item Key, then of course Zabbix can't create the items and hows this :

Cannot create item: item with the same key "K_ACK_report_2" already exists.
Cannot create item: item with the same key "K_ACK_report_2" already exists.
Cannot create item: item with the same key "K_ACK_report_2" already exists.
Cannot create item: item with the same key "K_ACK_report_2" already exists.

I found the solution.
The Item Key of a dependant item in an item prototype must be with brackets '[]'.
I made it work as expected by changing the Item Key to :

KondorACKCount[{#PELENV},{#MATCH}]

This should be mentionned in the documentation.
I'm not sure what is the purpose of imposing the brackets...
