Can FH change codes per logic

Can FH do this? If yes, how?
• Read site: .TXT file, example ‘DTNA_FORECAST_20160803AWsample.txt’, is attached.
• On the Write side same .TXT file but AL53 codes in the 2nd column should be changed per logic: If AL53 in the 2nd column AND (013 or 058 or 065) in the 3rd column THAN change AL53 to AL53X [or append X].
When designed correctly change from AL53 to AL53X should be done only in the top three rows of the sample file.
Thank you for assistance,
Andrew

Hi Andrew,

Of course, that´s the power of FlowHeater

I’ve made as short example for you, please have a look to the attachment.

Example description
First you need one String Append Heater to create the check condition for the IF-THEN-ELSE Heater . The String Append Heater combines the second and the third column with “#” as delimiter, for example “AL53#013”. The output can now be checked in the If-THEN-ELSE Heater . In your case you need three “or” conditions like the screenshot below.

Is this the cases (second input) you need one more String Append Heater to add the X at the end of the field content. Otherwise (else, third input) you have to put the second column directly without changes to the IF-THEN-ELSE Heater .

Very quick and comprehensive response. Thank you Robert.
