Heyas, I came up with a problem and not sure its possible to overide

I'm making a dataport which has some fields I'd need to export but I also would need to combine a code type field and Option type field like:
Code | Option
12345 | 1
Exported:
Code+Option
123451
Is it possible to make? I'm not so familiar with Navisions datatype conversions
K.S.

If however they insisted on combined version then you can do it by defining a variable in dataport and setting it as dataitem's dataport field
then in that dataitem's OnBeforeExportRecord() you can set a value for your "virtual" field
I'm not sure how theyr program works, my boss just gave me the schema how'd they need the information for the export file and the last colum they have they'd need a line of code (numbers) which consist work 5 numbers that 12345 and add to that the type of payment like 1 means normal work and 2 for over work. ex. 123451 or 123452.
