What is the meaning of this error ?.
I searched thru documents and all i can find was sms service, but without those error. Anyway, what does this stands for ?
Hi,
it is ADL_RET_ERR_PARAM according to ADL user guide… so parameter error…
So you missed the section at the end of the ADL User Guide titled “Error Codes”, then? 
The Error code values, names, and descriptions are listed there!
In fact, many ADL API calls can return -2 (ADL_RET_ERR_PARAM) - not just the SMS Service.
See the individual API Call descriptions for details…
I was searching in the ADL_development _Guide.
Sorry
