An Enhancement has been noticed to allow setting of print-parameter PRCMP to "Do not Append Jobs" so the checkbox is enabled. Currently none of the SAP AbapRun templates include this parameter.
Function Module BAPI_XBP_JOB_ADD_ABAP_STEP from SAP XBP interface is used to submit the ABAP program. It can only manage print parameters currently with BAPIPRIPAR structure. PRCMP however is not included in the structure. This has been confirmed as not a bug but a SAP limitation.
Allow and implement the parameter with extprintparameters
