Need help with RecArrayPkg.MergeSimilarRecArrays()

Andy_Simon_and_Ratna_BPD_Team_(x-hpsgsales2user1_-

Hi,i am quite clueless after being hit with the error during runtime - "a wrong argument type was specified". i have attached the codes and i have found out the culprit is the variable "execResult". can anyone advise if a typecasting operation is required? i have seen codes that pass in a dynamic type variable when the function asks for RecArray, but still it works fine.thanks in advance,Simon
