How To Fix SPRX299 - SUPPRESS_DIALOG set for transportable package but no TRANSPORT_NUMBER

SAP Error Message - Details

• Message type: E = Error

• Message class: SPRX - Proxy Generation

• Message number: 299

• Message text: SUPPRESS_DIALOG set for transportable package but no TRANSPORT_NUMBER

What causes this issue?

Proxy background generation is called with parameter SUPPRESS_DIALOG for
transportable package &V1& but parameter TRANSPORT_NUMBER not specified.

System Response

So far, this is only a warning,
but may result in an follow-on error when during generation new objects
arise which needs to be assigned to a transport request.
With SUPPRESS_DIALOG = 'X' the popup to specify the transport request is
suppressed and consequently saving the proxy will result in an error.
For a scenario where the relevant objects
are not transport relevant
are already assigned to transport request or
nothing is saved/activated at all (check scenario)
no error will raise.

How to fix this error?

In context of mass generation specify TRANSPORT_NUMBER in selection
dialog.
For a programatic usage of background generation specify correct
parameter TRANSPORT_NUMBER or set SUPPRESS_DIALOG to SPACE.
