Dear Employer,
After read your requirements carefully, I finally understand it.
Most of the works are done by SQL script to calculate the FinishPartNum by CustPartNum or MFGPartNum.
Then write the result to excel file. This part will be done with c# code.
I'm confident that I can finish it before the deadline.
Please PM me over chat, then we can have a detail discussion!
Thank you for your opportunity.
