You are trying to update your SPAM version on your SAP system and process canceled with the error CHECK_REQUIREMENTS –> QUEUE_NOT_EMPTY.In this case, you can check the below steps to clarify and solve the issue…

Triying to import “SPAM/SAINT” and process cancel with “CHECK_REQUIREMENTS”  message ;

Queue log shows that reason of the error is “QUEUE_NOT_EMPTY”

Now we should check the buffer and if some entries are already listed here,then we need to clear before contiue the process.

Related “tp” command is ;

tp SHOWBUFFER <SID> -DSOURCESYSTEMS= TAG=SPAM PF=<TP_DOMAIN_<SID>.PFL

As you can see, in our situation we have more than one request already in the buffer queue like shown below ;

Regarding the situation we need to continue with clening this queue step by step with below “tp” command ;

tp DELFROMBUFFER <request or support package> <SID> PF=<TP_DOMAIN_<SID>.PFL

Check the buffer queue again with the related command.

tp SHOWBUFFER <SID> -DSOURCESYSTEMS= TAG=SPAM PF=<TP_DOMAIN_<SID>.PFL

If everything is clean, now we can continue the update process from SAPM/SAINT tcode

Should be completed with success…
