When designing a report, you encounter such a problem, dynamically generate reports, for example: Table A: A1 (CHAR3), A4 (CHAR3), A4 (CHAR3), A4 (CHAR3), A4 (CHAR3), A4 (CHAR3) , A5 (Char (28) Five fields, Table B: There are three fields of B1 (50), B2 (6), B3 (4), and now want to dynamically generate reports in the crystal report according to different tables. When you first select watch a in the interface, print the report of the expression A. When you choose B. Dynamic generate report B. Do you have a trick or good advice now. Now I am very urgent. Thank you !!!
