Hi Daytrader, From previous threads, I know you are very dedicated to SAP. SAP columns: 1s (I should write 1) 2s ( 2) 3s (4) 4s + (4) Could you tell me where I can find SAP information, like: • If 1s is LC, which NOR system should I use? • If 1s is MC “ “ “ “ ? • If 2s is LC, etc. Something similar to that. As you know, sometimes, not sure which system to use, therefore, with SAP (additional information) can help us make a decision. Thanks.
