Hi. I just read it all and there are still tings you failed to address, so, even though you wrote that if we have questions not to bid, here they are:
1) You did not note what the 'partial' output files naming convention would be(this is expected, if what you say about the 11000 rows is true, on each and every run, so it's important not to overwrite outputs)?
2) There's no mention if the "quantity and tax" columns in the output will be "static" or calculated in any way?
3) There's no mention where any of the "suppliername,ImageAll,proImg1,proImg2,proImg3,proImg4,prodImages" columns data for the output will come from.
Please elaborate further on these so the task ahead can be properly assessed.
Regards,
Dobri
