Issues when Generating

If the generation fails, the problem is reported to the user. If a problem occurs when generating the business object runtime, it can be one of the following types:

• Problems in the connection to the application server. In this case, check whether the JCA connectivity is set up correctly. See Generating the Runtime.
• Problems in processing the template. Such problems may be caused by in incorrect model. Check whether any problems are reported by the LN Studio and whether the constraints as specified in section Modeling the Business Interface Implementation are met.
• Problems in registering the business object in the application server, such as insufficient authorizations or an incorrect implementation identifier. Refer to section Generating the Runtime on prerequisites for the LN application server.
• Compilation errors in the generated libraries. These may be caused by errors in the hooks (see Using Hooks for LN), problems as reported by the LN Studio, or violation of constraints as specified in section Modeling the Business Interface Implementation.

Regarding compilation errors, to have a closer look you can use the Program Scripts / Libraries (ttadv2530m000) session in LN to analyze the problem by compiling or viewing the libraries. You can also view the generated source in the output folder of the LN Studio project.
