Variant which doesn't exist causes a error.(Workflow)

Hi,Experts!

I am facing the problem that a program variant which doesn't exist causes a error.

The program was executed in background job(SE37).

First, I did copy system data from SystemA to SystemB and the job was copied in the same way as other system data.

Then, I tried to execute the job in SystemB, but the error occurred.(Variant &0000000000000 is not exist.)This Variant is not exist both systemA and systemB.

The program is

RSWWCOND

RSWWCLEAR

RSWWDHEX

...

If anyone have some information, please help me to solve this problem.

Thanks.
