Need ability to load file with "complex" Master/Detail structure

[redflowIT]

I have a file with a structure like this: HEADER RECORD TYPE1 RECORD TYPE2 RECORD TYPE3 RECORD TYPE3 RECORD TYPE1 RECORD TYPE2 RECORD TYPE4 RECORD TYPE5 TAIL .... in which there are many groups that starts with HEADER and ends with TAIL This is an example Test.txt

and those are specs: CBI-RND-001 6_05_ENG.pdf

I could use the Read from stream With multiple fixed record types but when I get the list of RECORD TYPEx I don't know in which group the record was readed. Is it possible at least to have the line number of each records?

Thank you Regards
