error T0011: invalid system description type '%s'

Cause

This error occurs when an invalid system description is specified. TDL has a fixed set of system definition types like Events, Formulae, Form Keys, Menu Keys, TDL Names, UDF, and Variables. %s : System definition type

Solution

Correct the definition type to a valid type.

Example

[System: UDFs]

In the above code, a system definition called UDFs is specified which is not a valid system definition type. Hence the message error T0011: The system description type 'UDFs' is invalid. appears.

The code is corrected by changing the definition name to UDF.

[System: UDF]
