Hi Drools, Requires clarity on referring data in Drools Decision table, Consider a IN case as like below, [cid:image001.png@01CF7E9C.169B05D0] Here the values for IN case are "F" and "M" are mapped from different sheet using the reference CONCATENATE("""", 'user-gender-datasheet'!C15, """, """, 'user-gender-datasheet'!C16, """"). When the values for IN grows, then Excel sheet references would be not maintainable. Is there another approach available to map the values from different sheet in drools decision table? -Shrinath [Aspire Systems] This e-mail message and any attachments are for the sole use of the intended recipient(s) and may contain proprietary, confidential, trade secret or privileged information.
