Recently we have been asked to design a message model which shows as a report like below. It was a nice report and they want the same intact.
Entry Per Post Date GL Account Description -------------------------------------------------------------- 16524 01 09/15/2018 123456 Test 16524 01 09/15/2018 123456 Test 16524 01 09/15/2018 123456 Test 16524 01 09/15/2018 123456 Test 16524 01 09/15/2018 123456 Test 16524 01 09/15/2018 123456 Test 16524 01 09/15/2018 123456 Test 16524 01 09/15/2018 123456 Test 16524 01 09/15/2018 123456 Test 16524 01 09/15/2018 123456 Test
After playing with DFDL Fixed Length format couple of times, we were able to achieve the desired format and it was really interesting when you know the power and simplicity of DFDL. The message model created is
