As the SAP connector creates SAP objects, such as, for example, function modules, into the SAP development system, these changes need to be transported into QA and production systems once the development is done. The SAP's change and transport system uses the SAP Transport Layer Name to identify the route a change has to take. A transport layer is assigned to each development class and thus to all objects in that class. The transport layer determines:
In which SAP System developments or changes to the repository objects are made
If objects are transported to other systems within the group when development work has been completed
A consolidation route is created from the development system to the quality assurance system through the transport layer Z<SID>
. It then becomes the standard transport layer for customer development and customizing.
A consolidation route is created from the development system to the quality assurance system through the transport layer SAP
for the transport of SAP Standard objects.
It is important to specify the correct transport layer name before running the RKM SAP ERP for the first time. Perform the following steps to identify the list of defined transport layers in your SAP landscape:
By default, the RKM option SAP_TRANSPORT_LAYER_NAME is set to SAP
. Ask your SAP basis admin which transport layer you should use. This transport layer name must be set on the SAP_TRANSPORT_LAYER_NAME RKM option. A wrong or invalid transport layer name will cause serious delays during the installation process.
