Data load in a process chain failing.

Hello All,

I receive a MESSAGE_TYPE_X runtime error for a data load in a process chain failing.

Among other information in the run time error long text is the following text which I have depicted in square brackets [The termination occurred in the ABAP program "SAPLRSPC_BACKEND" in "RSPC_PROCESS_FINISH". The main program was "SAPMSSY1 ". The termination occurred in line 71 of the source code of the (Include) program "LRSPC_BACKENDU05" of the source code of program "LRSPC_BACKENDU05" (when calling the editor 710).]

An additional message is [Process &1, variant &2 is not scheduled waiting for event &3 &4].

Please advise on what the problem is and how to solve it.

Thank you in advance.

Regards,

Keith Kibuuka
