Dear All Tdl Experts, I have written one report for ledger approval. In All Ledger Master, there will be appear one logical field only in alteration mode. Only if the ledger having logical value "yes", that ledger should be approved one. In my report all the "No" values ledger will appear correctly. I put one button to change the value No to yes, without entering into the ledger Master. My report is working well, But the function is not working. In calculator Panel showing "Execution failed" Message. I tried in many ways, but it is not working. I have attached my code and sample company. please correct my code. Thanks in Advance Thanking You
