L-EVNT-DATA Array error (what table Cobol is referring?)

Hello - I got error while processing AM Calc GPPDPRUN - Array Error (refer below). Seems Array size increase can help but at this time can't make any changes in the cobol code. So need to know what table it is referring so that we can delete data to avoid this error. Appreciate a quick response.

Internal array overflow occurred for array %1 defined in copybook %2 with a max array count of %3

      %1--> L-EVNT-DATA                  

      %2--> GPCDPDM5                     

      %3-->        50           

Thanks
