Basis SP 18 to 20, can not logon through SAPGUI - Syntax Error

Question

Hello Experts,
We had started ECC6.0 SP18 to SP20 patches and now we are getting Syntax error in program "CL_WB_CROSSREFERENCE==========CP ". for most of the transactions executed.
1. Job RDDIMPDP is also failing with message
Program RDDIMPDP is running in client 000                                    
Context TERNAL_INFOS does not contain any fields                     
Context TERNAL_INFOS contains errors and could therefore not be generated     
Context BANK_CTX_JC_REPORT modified                                           
Internal session terminated with a runtime error (refer to ST22)         
Job cancelled                                                   
2. Here are the details of this short dump, as soon as we get the short dump we get message in the status bar saying "Context BANK_CTX_JC_REPORT modified".

3. Tried to generate the program manually through SE38 -> CL_WB_CROSSREFERENCE==========CP  --> but it dumps with same message line 7:                                                                               
""PROGRAM-" expected, not "PROGNAME_"" 
Appreciate your inputs in resolving this issue.

Answer 1

Hello Experts,
Further investigation on system showed that we had implemented SNOTE 1374978 - which seems to be causing the problem.
Now as Support packages (SPAM) has locked SNOTE transactions also - is there any way that we can deimplement the above sap note from our system.
Thanks
